In the gardenbeaut vs efcut wood chipper comparison, I pick the EFCUT R30 for most buyers and the GARDENBEAUT S1 for one kind of owner: the one who wants the simpler blade job. Both are 7 HP gas machines that take solid wood up to 3 in through one opening, and both list 47 kg overall in their manuals. I run a 3.7-acre apricot and plum orchard, and the winter pruning pile along the rows is the job I held each machine against. Below I set them side by side on cutter, rotor access, blade care, weight and warranty.
GARDENBEAUT vs EFCUT Wood Chipper: My Verdict in Short
The EFCUT R30 is the better buy for most owners, because it gives the same 76 mm (3 in) limit, the same 7 HP engine and the same manual weight as the S1 and sits lower in the mid-range price tier. The GARDENBEAUT S1 7 HP Gas Wood Chipper earns its place at the upper end of that tier only for a buyer who wants a screen grille at the discharge, two named check windows and a blade guide with no gap to set. Every row in the table that does not name a difference is a tie. If neither machine fits, my roundup of the best wood chippers overall lists nine picks for branches and yard waste.
| Row | GARDENBEAUT S1 | EFCUT R30 |
|---|---|---|
| Machine type | Gas wood chipper, one feed hopper, screen grille at the discharge | Gas wood chipper, one feeding chute, adjustable discharge chute |
| Engine | 7 HP maximum, 212 cc, 4-stroke OHV, recoil start | 7 HP maximum, 212 cc, 4-stroke OHV, recoil start |
| Chipping capacity, maker’s words | Maximum diameter material: 76 mm (3 in), solid wood, through the feed hopper | Maximum diameter material: 76 mm (3 in), solid wood, through the feeding chute |
| Cutting system, manual’s parts list | Rotor with 2 blades and 6 shredding knives | Cutting roller with two L120 two-edge blades and one fixed blade |
| Feed | Gravity, pulls wood in on its own | Gravity, pulls wood in on its own |
| Collection | Discharge chute, no bag | Discharge chute, no bag |
| Weight, manual’s overall figure | 47 kg (about 104 lb), basis not stated | 47 kg / 103.62 lb, basis not stated |
| Wheels | Two wheels, pull handle, support frame | Two wheels, pull handle, support base |
| Bystander distance, manual | At least 10 m (about 33 ft); I keep to the 75 ft other makers print | At least 10 m (about 33 ft); I keep to the 75 ft other makers print |
| In the box | No bag, no push tool, no engine oil in the packing list | No bag, no push tool, no engine oil in the packing list |
| Warranty, manual | One year against construction faults, blades and consumables excluded | One year against construction faults, blades and consumables excluded |
| Reduction ratio, listing figure only | 20:1 on the listing, none in the manual | 15:1 on the listing, none in the manual |
Two rows decide the choice: the cutting system and the blade job. The R30 wins on cost tier, and the S1 wins on access to the rotor.
What Is Actually Different Between the S1 and the R30
On paper the two machines are close to twins, and the paperwork backs that up. Both manuals print the same maker’s contact block, Qingdao Zhonglang Machinery Technology, the GARDENBEAUT manual is hosted on EFCUT’s own manual page, and the safety text of the two manuals is word for word the same. A gardenbeaut wood chipper of this size is therefore easy to mistake for an EFCUT, and the engine, capacity, feed, bag and warranty rows will not tell you which to buy.
The model names need one line of care. The S1 manual is titled GB-S1.0 while the Amazon listing says GB-S1, which is the same model. The R30 manual is titled R30 (R0) and covers both codes, so I call it the EFCUT R30 throughout.
Cutting System: Rotor With Knives or Cutting Roller
The S1 manual’s chipping-system table lists a rotor with 2 blades and 6 shredding knives, and its parts list adds a screen grille at the discharge. The R30 manual’s parts list names a cutting roller with two L120 blades that have two cutting edges each, working against one fixed blade. Neither maker calls its cutter a drum or a disc, so I use the manual’s part names and nothing more. My comparison of the EFCUT C30 LITE and R30 explains the difference between flywheel knives and a cutting roller.
The first thing I did with the gardenbeaut s1 wood chipper was trim a forked plum twig before it reached the hopper mouth, because its manual says badly twisted brash should be trimmed before chipping to avoid thrashing in the feed hopper. Both machines pull wood in on their own, and the manual warns that the wood is drawn into the cutting blade quite quickly. I let go of every branch the moment the machine took it, which is also what the manual’s line to release the material before it engages the rotor asks for.
The listings print 20:1 for the S1 and 15:1 for the R30, but neither manual prints a reduction ratio, so I do not rank the two on it. The R30’s cutting roller is the one real difference in how the wood is cut, and the maker makes no claim that it cuts better. Winner: a draw, because both manuals give the same 76 mm limit through one opening and the same gravity feed.
What Each Machine Takes and What It Does Not
Both manuals print the limit as maximum diameter material of 76 mm (3 in) and describe the machine as designed to chip solid wood, through the one opening each machine has. Neither manual describes a separate shredder opening, and neither mentions leaves, so a pile of leaves and green garden waste is the wrong job for both. The capacity is a ceiling, and a piece that is too tough or too large slows the engine down, which is the cue to let go and sort the wood again. My roundup of the best 3-inch wood chippers lists nine gas picks with the same limit.
On the R30 I sort first: plum limbs thicker than the 76 mm chute go to the firewood stack before the engine starts. The manuals ask for clean brushwood only and list muddy or dirty wood, roots, potted plants, bricks, stones and metal as things that never go in, and road sweepings dull the blade with grit. Some species of trees and bushes are poisonous, and the manuals tell you to check the material before you start and to avoid confined spaces. On the S1 I keep diseased plum wood in its own pile, apart from the clean brushwood, so I know what went into the machine.
What Not to Feed
Feed only clean wood and plant material that your manual allows, into the opening it names and within that opening’s limit; a leaf mulcher such as the WORX WG430, Sun Joe SDJ616 or Flowtron takes no branches, sticks or brush. Never put in roots, stones, soil, metal, nails, wire, glass, plastic, cans or bottles. Leave out pressure-treated wood, painted wood and lumber unless your manual allows them; several manuals ban treated and kiln-dried lumber outright.
Trees to cut down, limbs thicker than 76 mm and large brush piles are a job for a tree professional, and anything near a power line goes to the utility and its qualified line-clearance crews. Winner: a tie, because both stop at 76 mm of clean solid wood.
Safety Setup Before You Start Either Chipper
A chipper has a fast-spinning rotor behind the inlet, and the rotor keeps turning after the engine is off. Everything in this section applies to both machines, and where a manual adds a rule of its own I name it.
Only an adult who has read the manual and understands the controls operates either machine, never a child and never anyone tired or impaired by alcohol, drugs or medication. One person feeds and runs the controls, and a helper never touches the controls and stays outside the work area.
Hands Out
Never put your hands, feet or any part of your body into the hopper, the chute or the discharge while the machine is running or the rotor is still turning, and never reach past the rubber flap or the mouth of the chute. Push short pieces in only with the paddle or push tool your manual supplies, or with the next branch or a small stick as your manual describes, never with your hand or foot.
Neither box holds a push tool, so the next branch or a small stick is the only option. CDC reports that chipper operators can be caught in the feed mechanism and pulled into the rotating knives, and that the hood can strike a person who opens it while the knives still turn (1). A plastic-surgery report on yard shredder and chipper machines describes severe operator hand injuries that can need complex reconstruction (2).
Feeding Position
Stand to the side of the hopper or chute, never directly in front of it, and feed branches butt end first. Hold the branch near its outer end with an open hand, never wrap your fingers tightly around it, and let it go as soon as the machine draws it in; never follow a branch into the chute. Feed only the material and the branch size your manual allows, into the opening it names.
Both manuals say to stand to one side of the hopper, and the decal on the hopper front says standing in front adds noise, dust and ejected particles.
Clothing and Protection
Wear safety glasses or goggles with side shields marked ANSI Z87.1, and a full face shield where your manual asks for one; hearing protection; gloves only as your manual directs, and where it asks for gloves, snug ones without loose cuffs or drawstrings; long pants and sturdy non-slip boots; and respiratory protection as your manual requires (WEN: NIOSH-approved dust masks or other respiratory protection during operation and cleaning; Woodland Mills: a dust mask in dusty conditions). Never wear loose clothing, scarves, jewelry or dangling drawstrings, and tie up long hair: anything that catches on a branch can be pulled toward the inlet.
The GARDENBEAUT and EFCUT manuals ask for a safety helmet with a mesh visor and ear defenders, work gloves with an elasticated wrist, safety boots and close-fitting clothing, with a face mask where it is appropriate.
Neither manual prints a sound figure. On the S1 the noise at the hopper was louder than I expected, even with ear defenders on, and the hopper decal says as much. NIOSH recommends 85 dBA averaged over an eight-hour day and half the exposure time for every 3 dBA more (3), and a Cochrane review notes that poor fit may limit the protection of about 40 percent of earplug users (4). I wear the defenders the manual names, fitted properly, from the first pull of the cord.
For dust, an Italian survey of chipping operations found operators working in the open had about three times the wood dust exposure of operators in an enclosed cab (5), and volunteers who breathed wood chip mulch dust for a short time developed flu-like symptoms and lung inflammation in a small study (6). I wear a dust mask for dry wood.
Thrown Objects and Bystanders
The machine can throw chips, stones and metal out of the hopper and the discharge. Keep children, pets and other people out of the work area, at least the distance your manual prints (the Champion, MTD and Yardmax manuals ask for 75 feet), and stop the machine at once if anyone comes closer. No distance makes a work area safe on its own: keep watching it. Never point the discharge at people, animals, windows, cars or buildings, and never look into the hopper or chute while the machine runs.
GARDENBEAUT and EFCUT print a minimum of 10 metres (about 33 ft), and I keep to the 75 feet the other makers ask for.
Site and Weather
Set the machine on firm, level earth or grass, never on a slope, on pavement, concrete or gravel, or close to a wall or building, where chips and stones ricochet. Clear the area of stones, wire, rope and other loose objects first, and work in daylight. Never work on wet or slippery footing, where you could slip toward the inlet, never run an electric chipper in rain or in damp or wet conditions, and stop any chipper and seek shelter if you hear thunder or see lightning.
Both manuals say not to work on an incline, to keep the machine well supported so it cannot move, never to use it inside buildings and to run it only in a well-ventilated area, because the exhaust is dangerous.
Kickback
If a branch will not feed, kicks back or cannot be controlled, stop feeding and let go: never chase it into the chute or try to hold it back. Remove trapped material only after the full maintenance shutdown for your power type, with every extra step your manual adds. Keep the discharge area clear: chips that build up there can make new material kick back toward you.
The manuals tell you to watch the discharge at all times and to stop immediately if chips stop coming out while the machine is still taking wood in.
Pre-Start Check
Before every start, check that the guards, flaps, hoppers, discharge chute and any collection bag your manual requires are fitted and secured (Earthquake forbids running without its debris bag), and that knives, fasteners, the cord or the fuel system are undamaged. If the machine starts to vibrate abnormally, stop it at once, complete the full maintenance shutdown and have the cause fixed before you restart.
Both manuals forbid starting the chipper without the feed hopper and guards securely in place.
Fatigue
Feeding branches is heavy, repetitive work: take breaks, and stop when you are tired or your attention slips.
Starting the Engine
Pull the starter cord slowly until you feel resistance, then pull rapidly, and never start the engine with material in the hopper or chute.
Reaching the Rotor and Changing Blades
This is the section where the two machines differ most, and it is the one where a shortcut costs the most. Complete the full shutdown in the box below before you touch anything behind the hopper.
Full Shutdown Steps
Shutdown before you clear a clog, open a hopper, chute or panel, touch knives, hammers or the cutting line, empty a bag or bin, move, tilt, store or leave the machine. Never use your hand, foot or any body part to unclog it, even after shutdown, and clear a blockage only with the method and tool your manual names. Gas chipper: turn the engine off, wait until the rotor and every moving part have stopped completely, let the engine and muffler cool, remove the key where fitted, and pull every spark plug wire off and secure it away from its plug. Then add your manual’s own steps in its order: the S1 blade guide pulls the plug cap off the spark plug before blade work and then removes the bottom feed hopper, while the R30 guide prints no plug-cap step, so pull the spark plug wire off first as written here. Never open a hood or access panel before every moving part has stopped. Refit every guard, flap, hopper, discharge chute and any collection bag your manual requires before you restart.
For blade work on the S1, complete the full shutdown in the box above, plug cap off included. The S1 guide then removes the bottom feed hopper and the front window cover plate, uses an Allen key and a 13 mm socket with new locknuts every time, and calls for riggers gloves.
The housing has a front and a back check window, which gives it two named ways in after the shutdown. The manual also says thin, ductile branches can burn onto the cavity cover, which is the one to watch on hedge stems. After the full shutdown, the cover comes off to clean it.
On the R30, every blade change is a gap job. You need 16 mm and 13 mm spanners, a thickness gauge and the safety screw that holds the roller, and the gap between the fixed blade and the cutting roller has to land between 1.0 and 1.5 mm. The manual ends the guide with the line that this is important for safety.
I read the gap steps through twice before touching a spanner, because a gap set by eye is a gap set wrong. Both makers say to re-sharpen after about 3 hours of fresh wood or about 1 hour of dry wood.
A slow feed is the sign of dull blades.
Never use your hand, foot or any body part to unclog the machine, even after it is shut down. The manuals’ own clog text sends a gloved hand into the rotor housing, and the maker’s own warning box beside it says not to reach into the housing with unprotected hands, so I do not follow those steps. Neither manual names a clearing tool.
Complete the full shutdown in the box above, open only the check window or panel the manual names, and if the blockage will not come out without a body part, stop and contact the maker’s support listed in the manual. Continuing to feed a blocked machine only compacts the chips in the rotor housing, which the manual says makes the clog hard and slow to clear.
Winner: the S1, because its blade job has no gap to set and its housing has two named check windows.
Fuel, Oil and Storage
Both machines use the same engine on paper, so the fuel and oil rules are shared. The manual specifies 87 or higher unleaded gasoline with a maximum of 10 percent ethanol, a 2.8 litre tank and SAE 15W-40 oil, and the packing lists hold no engine oil, so you buy it separately. The S1 takes 0.5 litres and the R30 0.55 litres of oil. Fill the tank no higher than the maximum fill indicator and keep a fire extinguisher on site, as the manuals say. My roundup of the best gas wood chippers covers the engine side across nine picks.
Gas Chipper Fuel and Fire
Refuel a gas chipper outdoors with the engine off and cooled for at least two minutes, as the Champion and MTD manuals say, with no smoking, flames or sparks nearby; open the cap slowly, wipe spills and never start the engine where fuel spilled. Never run a gas chipper indoors or in a garage or shed, even with the doors open: the exhaust contains carbon monoxide, which you cannot see or smell. Before you start, with the engine off and cool, clear chips and dry leaves from the engine and muffler; if debris builds up during work, complete the full gas maintenance shutdown, spark plug wire off included, before you clean it away, and keep every cooling and combustible-material clearance your manual gives (Champion: 3 feet around the machine for cooling and 5 feet from combustible materials and dry vegetation; SuperHandy GUO148: 2 m, 6.5 ft, from flammable materials).
The GARDENBEAUT and EFCUT decal says to let the engine cool for 1 minute, and I wait the longer two minutes. Their refuelling distance is more than 10 metres from where you work, which is a refuelling rule only and never a bystander distance.
For storage, the manual says to turn the fuel valve off, keep the engine upright and make sure no debris or water is trapped in the rotor housing, so complete the full shutdown in the box above first. Store it dry and out of children’s reach, and never with fuel in a building near a furnace, water heater, dryer or other flame or spark source. After storage, drain the carburetor completely, replace the storage fluids and run the engine 15 minutes at half throttle before any cutting, then bring it to full throttle for a further 5 minutes.
Weight, Wheels and Moving It
Both manuals print an overall weight of 47 kg, which is about 104 lb, with no basis stated, and I compare no other figure against it. The Amazon listings print 119 lb for the S1 and about 122 lb for the R30 on bases they do not state, so I use the manual figure for both. Each machine rolls on two wheels with a pull handle, and neither manual gives the wheel size.
Before you move, tilt or lift either machine, complete the full shutdown in the box above, since the manuals ask for the engine stopped first. Two people lift a heavy unit, as the Earthquake and Champion manuals say, and never use the hopper handles to strap it down for a journey. Winner: a tie, because the manuals give the same weight and the same two wheels.
Warranty, Maker and Manual
Both manuals print a one year warranty against machine construction, with blades and other consumables excluded, and ask you to register at efcut.com. That makes the efcut wood chipper warranty the same for both, whichever brand name is on the hopper. The engine’s own care sits in a separate generic engine manual that the maker links, so keep it beside the chipper, and neither manual prints a noise figure, an engine make or a push tool. Winner: a tie.
Choose the GARDENBEAUT S1 If
The S1 suits an owner who values the easier blade job and the access to the rotor over the lowest price in the mid-range tier. It is a plain machine with one hopper, gravity feed and no bag, so the choice rests on the details below. I describe it in full in my GARDENBEAUT S1 chipper review.
- You change blades yourself: the guide has no gap to set, and it names a plug-cap step.
- You want two windows: the housing has a front and a back check window.
- You want a screen grille at the discharge: it is on the S1 parts list and on no R30 parts list.
- You skip it if the pile is mostly leaves, since the manual describes no shredder opening and the machine takes no leaves. My roundup of the best wood chippers for leaves ranks seven machines for leaf cleanup.
For a pile of clean brushwood up to 3 in, I still pick the cheaper R30 unless the blade job matters to you.
Choose the EFCUT R30 If
The R30 suits an owner who wants the same class of machine at a lower position in the mid-range tier and will do the blade job properly. The efcut r30 wood chipper takes the same 76 mm of clean solid wood as the S1 through one chute, so the saving costs you nothing in capacity. I describe it in full in my EFCUT R30 chipper review.
- You want the lower price: same engine, same capacity and same warranty as the S1.
- You can set a blade gap: you own a thickness gauge and will read the steps before you start.
- You like an adjustable chute: the discharge chute aims chips away from people and walls.
- You skip it if you dislike precise blade work, because every blade change ends in a gap check.
The adjustable chute is the feature I use most on a pile near the trees: Before adjusting the discharge, complete the full shutdown for the machine in the shutdown box above. I turn it away from the tree row so the chips never pile against a trunk, and I leave a small gap between the chip layer and the bark. That habit costs nothing and keeps the chips off the drip lines.
My Pick for a Winter Pruning Pile
Neither machine is the one for leaves, green waste or limbs over 76 mm, and both ask for the same care with the rotor, the discharge and the fuel. Choose the S1 if the blade job and the access to the rotor matter to you, and skip both if you want a bag or a separate shredder opening. For most owners with a pile of clean brushwood up to 3 in, the gardenbeaut vs efcut wood chipper decision ends with the R30 and a steady hand on the blade gap. For branches and leaves, I compare nine machines in my roundup of the best wood chipper shredders.
Frequently Asked Questions
Is GARDENBEAUT the same company as EFCUT?
GARDENBEAUT and EFCUT point to the same maker in their manuals, which print the same contact block for Qingdao Zhonglang Machinery Technology in Qingdao, China. The GARDENBEAUT manual is also hosted on EFCUT’s own manual page, so the two brands share their paperwork, but neither manual says how the brands are owned.
Which is heavier, the GARDENBEAUT S1 or the EFCUT R30?
Neither is heavier on the makers’ paper, because the manuals of the GARDENBEAUT S1 and the EFCUT R30 both list an overall weight of 47 kg with no basis stated. The Amazon listings print other weights on unstated bases, so compare the manual figure and plan on two people to lift either one.
Does the GARDENBEAUT S1 or the EFCUT R30 come with a bag?
Neither the GARDENBEAUT S1 nor the EFCUT R30 comes with a bag, since both manuals list a discharge chute and both packing lists hold no bag. Chips land where the chute points, so aim the discharge away from people, windows, walls and the base of trees, and keep it clear.
What is the difference between the GARDENBEAUT S1 and the EFCUT R30?
The difference between the GARDENBEAUT S1 and the EFCUT R30 is the cutter and the blade job: the S1 has a rotor with 2 blades and 6 shredding knives plus two check windows, while the R30 has a cutting roller needing a 1.0 to 1.5 mm gap. Engine, capacity, feed and warranty match.
Do the GARDENBEAUT S1 and the EFCUT R30 chip the same size of branch?
The GARDENBEAUT S1 and the EFCUT R30 chip the same size of branch on paper, since both manuals print a maximum diameter of 76 mm (3 in) of solid wood through one opening. Anything thicker is a job for a larger machine or a tree professional, never for forcing it in.

Safety Note: Only an adult who has read the manual and understands the controls should use a wood chipper or shredder, never a child or anyone tired or impaired. The rotor, knives, hammers or cutting line behind the inlet can draw in a hand, a sleeve or a glove faster than you can let go, and they keep turning after you switch the machine off. Never put your hands, feet or any part of your body into the hopper, the chute or the discharge while the machine runs or the rotor still turns, never reach past the rubber flap or the mouth of the chute, and push short pieces in only with the paddle or push tool your manual supplies, or with the next branch or a small stick as your manual describes. Stand to the side of the hopper, never in front of it, feed branches butt end first with an open hand near the outer end, and let go as soon as the machine draws the branch in; if a branch kicks back or will not feed, stop feeding and let go, never chase it into the chute. Feed only the clean material your manual allows, into the opening it names and within that opening’s limit (a chipper chute and a shredder hopper have different limits, and a leaf mulcher takes no branches, sticks or brush), and never stones, soil, metal, nails, wire, glass or plastic. The machine can throw chips, stones and metal: keep children, pets and other people out of the work area, at least the distance your manual prints (the Champion, MTD and Yardmax manuals ask for 75 feet), stop at once if anyone comes closer, and never point the discharge at people, animals, windows, cars or buildings. Set the machine on firm, level earth or grass, never on a slope, on pavement, concrete or gravel, or close to a wall, work in daylight, never work on wet or slippery footing where you could slip toward the inlet, never run an electric chipper in rain or in damp or wet conditions, and stop and seek shelter for thunder or lightning. Wear safety glasses or goggles with side shields marked ANSI Z87.1, a face shield where your manual asks for one, hearing protection, gloves only as your manual directs (snug ones without loose cuffs or drawstrings where it asks for them), long pants and sturdy non-slip boots, and respiratory protection as your manual requires (WEN asks for NIOSH-approved dust masks or other respiratory protection during operation and cleaning); never wear loose clothing, scarves, jewelry or dangling drawstrings, and tie up long hair. Before every start, check that the guards, flaps, hoppers, discharge chute and any collection bag your manual requires are fitted and secured, and stop at once if the machine starts to vibrate abnormally, complete the full shutdown below and have the cause fixed before you restart. Never use your hand, foot or any body part to unclog the machine, even after it is shut down. Before you clear a clog, open the hopper or a panel, touch the knives, empty the bag, move or tilt the machine or leave it: on an electric hopper chipper, switch it off, unplug it from the outlet by the plug and wait until the blades have stopped completely, and on a leaf mulcher switch it off, wait until all motion has stopped and unplug it by the plug, never opening any electric machine before it is unplugged and still; on a gas chipper, follow your manual’s own shutdown sequence and every wait it prints: the engine off, the rotor and every moving part stopped completely, the engine and muffler cooled, the key removed where fitted, and every spark plug wire pulled off and secured away from its plug or grounded where your manual says so; on a PTO chipper, throttle to idle, disengage the PTO, turn the tractor off, remove the key, set the parking brake, wait until all motion has stopped and disconnect the PTO shaft before any service. Complete every model-specific step and minimum wait in the order your manual prescribes before any access, clear the blockage only with the method and tool it names, and refit every guard and any required bag before you restart. Use an electric chipper only with an outdoor-rated extension cord of the gauge and length your manual gives, plugged into GFCI-protected power, and never touch it or the plug with wet hands. Refuel a gas chipper outdoors with the engine off and cooled for at least the time your manual gives (Champion and MTD: two minutes), open the cap slowly, keep smoking, flames and sparks away, wipe up spills and never start it where fuel spilled; clear chips and leaves from the engine and muffler only after the full shutdown, spark plug wire off included, keep every cooling and combustible-material clearance your manual gives (Champion: 3 feet around the machine for cooling, 5 feet from combustible materials and dry vegetation), and never run it indoors or in a garage or shed, even with the doors open, because the exhaust contains carbon monoxide. Take breaks and stop when you are tired.
