Wood Chipper vs Chainsaw: Which Tool Handles Which Branch Job?

The wood chipper vs chainsaw choice comes down to the job: a chainsaw cuts wood into pieces, and a wood chipper turns branches into chips. Neither replaces the other, and most branch piles need a saw or loppers first and a chipper second. After dormant pruning in the orchard I end up with a pile of twigs and a few limbs far too thick for any hopper, and sorting that pile shows fast which tool does which work. Below I compare what each tool takes in, where its size limit sits, how the two share one pile and how each can hurt you.

Wood Chipper vs Chainsaw: The Short Answer

A chainsaw cuts across the grain and leaves you logs, limbs and firewood lengths. A chipper shredder pulls branches through a spinning rotor and leaves you chips for mulch. One makes pieces and the other makes chips, so you pick by what you want at the end of the job, and the machine that sounds bigger has no say in it.

• Choose the chainsaw when the goal is wood in manageable lengths: thick limbs, a fallen branch, firewood. For the log side of that job, my comparison of a log splitter and a chainsaw shows what each tool does and when you need both.
• Choose the chipper shredder when the goal is chips or shredded leaves from branches that fit its rated branch diameter, which means mostly the thin wood from pruning.
• Own both when your land grows trees: a chainsaw and a chipper together cover the whole pile, with the saw cutting limbs down to size and the chipper taking the thin wood. My roundup of the best chainsaws for homeowners covers saws with a chain brake for yard cleanup.
• Use neither on wood that hangs overhead, sits bent under tension after a storm or touches a power line.

I sort before I cut anything, and that one habit saves more wasted effort than any piece of equipment.

What Each Tool Does to a Branch

The two tools work on wood in opposite ways, and that explains their size limits, their hazards and what you carry away afterwards. The saw makes one controlled cut. The chipper reduces the whole branch.

Chainsaw for Cutting Branches and the Pieces It Leaves

A chainsaw runs a looped chain of cutters around a guide bar and slices across the wood. What comes out is pieces: shorter limbs, logs, firewood lengths. The size limit is the bar. Alabama Extension calls a bar of 8 to 15 inches right for small limbs and a bar of 16 to 20 inches right for frequent thick limbs and trunks, and it treats bars over 20 inches as professional grade and not recommended for homeowners. My guide to how a chainsaw works walks through the engine, clutch, chain and brake.

The number on the box is the called length, and the wood a saw can cut through in one pass is shorter. According to Makita, the UC4051A carries a 16 inch bar with a 14 inch cutting length. When I compare a limb against a saw, I count against the cutting length. My guide on what size chainsaw you need matches bar length to the jobs around a home.

Wood Chipper for Branches and the Chips It Makes

A chipper shredder puts a spinning rotor, flywheel or flail behind an inlet. Knives cut branches into chips, and the inlet decides what the machine accepts. Sun Joe lists the CJ603E with a cutting diameter of 1.73 inches at its one feeding funnel, which is a rated branch diameter and not the size of the funnel. According to Earthquake, its gas chipper shredder takes limbs up to approximately 3 inches in diameter in the chipper cone, and nothing over 1/2 inch in diameter belongs in its shredder hopper, which the manual lists as 1/2 inch by 18 inches long. For a closer look at the parts, my guide on how a wood chipper works follows the rotor, knives and feed.

An electric leaf mulcher is a third kind of machine. The WORX WG430, Sun Joe SDJ616 and Flowtron mulchers take leaves, grass clippings and similar soft material, and their makers say they cannot shred branches or sticks. Wood thicker than the rated branch diameter is cut up or left for a larger machine or a professional, never forced in. My comparison of a wood chipper and leaf mulcher shows what each machine handles.

The Two Tools Side by Side

The chainsaw vs wood chipper comparison below uses the points that decide a job. Each row compares like with like, and the size limits are the makers’ own figures for the opening they name.

Two rows settle most piles: the size limit and what comes out. If the wood is within the rated branch diameter and you want chips, the chipper wins. If it does not fit, or you want logs, the saw wins.

Wood Chipper vs Chainsaw for Each Kind of Job

I sort my own jobs by what the wood is and where it hangs. These four cover most of what comes up around an orchard and a house lot.

Orchard Prunings and Small Branches

Dormant pruning takes 20 to 25 percent of the canopy volume out of my apricot and plum trees every winter, and nearly all of it is twigs and small branches. Live fruit wood is a job for loppers and a hand saw, and a power saw is for the rare limb too thick for them. The chipper deals with the pile afterwards. My comparison of a wood chipper and garden shredder looks at the same pruning job.

Chips from that pile go on the tree-row strips as mulch, a tidy end for thin wood. I keep them off the drip lines and leave a gap at every trunk. University of Illinois Extension asks for mulch at least 4 inches from the trunk, and University of Georgia Extension asks for 3 or 4 inches.

Thick Limbs and Firewood

A limb thicker than the chipper’s rated branch diameter is a saw job. The sawn lengths go wherever you use wood, and a chipper adds nothing to that work. Before I feed anything, I move the thick limbs to one side, because a branch past the manual’s stated size does not belong in a small unit. The mistake I watch for is a thick limb pushed at a hopper that was never built for it. My guide to 3-inch versus 4-inch wood chippers shows which size fits a brush pile.

Storm Limbs and Trees That Have to Come Down

A limb that hangs, tangles in other branches or bends under tension is neither a chipper job nor a job for a homeowner saw. Alabama Extension warns that bent wood can lash out with extreme force when it is cut, and it tells owners to hire professionals when the bend sits over their shoulders. A tree that has to come down is a job for a professional.

Leaves and Garden Waste

Leaves belong to the chipper shredder’s hopper or to a leaf mulcher, and the chainsaw has no part in them. In late October shredded leaves stay a light layer on the ground where whole leaves mat. Wet leaves pack many hoppers, so I wait for a dry day, feed leaves in small handfuls and keep the machine level. My roundup of the best wood chippers for leaves ranks seven machines for leaf cleanup.

How the Two Work Together on One Pile

On a mixed pile the saw and the chipper share the work, and the order matters. The chipper’s rated branch diameter sets every decision, so read it in the manual of the exact model before you start.

1. Sort the pile into thin wood, wood close to the opening and thick limbs.
2. Set the thick limbs aside for firewood, a larger rental machine with its own manual, or a professional. Never force them in. If those limbs are thick enough to become logs, my comparison of a log splitter and wood chipper shows which machine fits which job.
3. Cut long limbs down to lengths you can feed, with loppers or a hand saw where they are enough. Use the chainsaw only on wood lying on the ground, never on wood that hangs or sits under tension.
4. Stop the saw with the full stopping order in the safety section below and put it down, then walk to the chipper.
5. Feed what fits, butt end first, from the side, as the feeding position rule below describes.
6. Keep the chips off the drip lines and away from trunks when you spread them.

Here is a sample pile, sorted against the openings the makers print.

The 4 inch limb ends as firewood in both columns, and the 2.5 inch limb changes sides only because the two makers rate different branch diameters. The rating in your own manual decides, not these two examples.

Safety for Two Machines That Hurt in Different Ways

The CDC reports that wood chipper operators can be caught in the feed mechanism and pulled into the rotating knives, or struck by the hood when it is opened with the knives still turning (1). A review of fatal incidents among tree care workers lists being caught or dragged into woodchippers next to falls from trees, being struck by branches and electrocution (2).

A plastic surgery report describes severe hand injuries to the operators of yard shredder/chipper machines, mostly in fall and spring (3). Those cases come from workplaces and clinics, so they say nothing about your odds. They show what an inlet does to a hand, and the saw has its own ways of hurting you.

The Chainsaw Side

A chainsaw hurts through kickback, slips and contact with the chain. I keep this part to the rules the comparison needs, and the saw’s own manual and hands-on training come first. A beginner starts with small, simple cuts of wood lying on the ground. Oregon State’s warning is plain: never work alone with a chain saw, so keep another adult within earshot and outside the cutting area. Laboratory kickback tests show that the risk depends on the wood being cut and on where the bar tip touches it (4).

The Chipper Side

A chipper draws the material in by itself, so the danger sits at the inlet. Researchers who reviewed worker deaths on mobile hand-fed chippers found that the feed controls on those large machines do not let a trapped worker rescue themselves (5). Homeowner shredders are smaller and have no feed rollers, and their manuals still use words such as amputate. The rules below apply to every model, and the exact manual wins wherever it is stricter.

Stopping Each Machine

Every handover between the saw and the chipper, every clog and every cleaning starts with the full stopping order for the machine in your hands. Here are the orders in full, one for each power type this article covers.

• Chainsaw, stopping: release the trigger, engage the chain brake (on a battery or corded saw, if it has a brake lever), switch the engine or motor off and wait until the chain has stopped.
• Electric chipper, stopping: switch it off and wait until the blades or cutting line have stopped completely (they keep turning for a few seconds after the switch is off, as the Sun Joe and WEN manuals say); for any access, also unplug it and never open or clear it until it is unplugged and all motion has stopped.
• Electric chipper, maintenance and clearing (a clog, a jam, opening the hopper, the discharge or the access panel, cleaning, changing, sharpening or adjusting knives, hammers or the cutting line, emptying a bag or bin): stop as above, then pull the plug from the outlet by the plug, not the cord. The Sun Joe, PS10 and WEN hopper chippers: off, unplug, wait for the blades. The WORX WG430 and Flowtron leaf mulchers: off, wait for all motion to stop, unplug. Follow the exact manual and never open or clear it before it is unplugged and all motion has stopped. Never use a hand, foot or any body part to unclog the machine, even after shutdown: remove the blockage only by the method and with the tool the manual names. Gloves for knives and hammers as the manual specifies. Refit every guard, flap, hopper, discharge chute and any collection bag the manual requires before power goes back on.
• Gas chipper, stopping: turn the engine off and wait until the rotor and every moving part have stopped completely.
• Gas chipper, maintenance and clearing (the same jobs): stop as above, let the engine and muffler cool, remove the key where fitted, and pull the spark plug wire off and secure it away from the plug (or ground it against the engine where the manual says so). Never open a hood or access panel until every moving part has stopped (NIOSH). Never use a hand, foot or any body part to unclog the machine, even after shutdown: remove the blockage only by the method and with the tool the manual names. Gloves for knives and hammers as the manual specifies. Refit every guard, flap, hopper, discharge chute and any collection bag the manual requires before power goes back on.

Makers print no coast-down time in seconds for gas machines, so there is no number to trust: wait until nothing moves, and add the extra steps your manual prints. Champion prints this sequence: close the fuel valve and run the engine until fuel starvation stops it before clearing a clog, and for a serious clog let the unit cool and drain the fuel before you open the access panel. MTD prints this step: ground the disconnected spark plug wire against the engine.

Toro prints these steps: shut the engine off, wait five minutes for the flywheel and all parts to stop and cool, remove the key and disconnect every spark plug wire. Yardmax, Boss and SuperHandy GUO148 print the five-minute wait too. Feeding branches is heavy, repetitive work, so take breaks, and stop when you are tired or your attention slips.

Cost, Power Source and Noise

Both tools come in budget, mid-range and premium tiers, so the cost comparison between a chainsaw and a chipper depends on the tier you pick and on whether the job needs one machine or two. A saw plus loppers handles all the cutting. A chipper adds a second machine to plug in or fuel, store and maintain. My roundup of the best small-yard wood chippers compares light electric and gas picks.

Power source changes where each tool works. An electric chipper shredder needs an outlet or a heavy extension cord, so it works near the shed and not out in the rows. A gas model moves with the work. Next to a gas model I tried, the electric unit was quieter but tied me to a cord. My guide to electric versus gas wood chippers goes deeper on what each can chip.

Noise is the shared problem. The Sun Joe manual rates the CJ603E at 94 dB, and NIOSH recommends limiting exposure to 85 dBA averaged over an eight-hour workday (6). In a NIOSH sampling of landscaping workers, fuel-powered leaf blowers, string trimmers and chainsaws gave significantly more noise and carbon monoxide exposure than battery versions (7). That finding covers the group of tools, not chainsaws alone, but it points the same way for the saw: hearing protection every time, and gas exhaust outdoors only.

Do You Need a Chipper If You Already Have a Chainsaw?

The answer follows what you want from the wood. If you want firewood, or you only need limbs cut down to a size you can carry, the saw and a pair of loppers are enough. A chipper earns its place when you want chips for mulch, shredded leaves, or a pile of thin prunings reduced to something you can spread. My roundup of the best wood chippers for branches ranks nine picks by branch capacity and budget.

Chips can pay off in a planting. In a five-year blackberry trial, wood chip mulch raised annual yield by 15 percent and cut weeds (8). That was one crop in one trial, so it is no promise for apricots or plums, and where my chips go I keep the gaps at the trunks and the drip lines.

A Wood Chipper Alternative for Thick Limbs

For a limb past your machine’s opening, the best wood chipper alternative is the saw itself: cut it into lengths and use the wood. The other routes are a larger rental machine with its own manual, or a professional. A chipper works on the thin wood and the leaves, and the saw handles the rest. For firewood lengths, my roundup of the best chainsaws for firewood lists seven saws for bucking logs.

What to Remember Before You Buy Either One

Three checks settle the purchase. First, look at your last pruning pile: if most of it is thicker than the rated branch diameter of the chipper you are considering, a saw and loppers will do more for you. Second, decide what you want at the end of the job: logs and firewood call for the saw, chips and shredded leaves call for the chipper. Third, read the exact manual of any model before the first cut, shutdown order included. My own habit is to sort the pile before either machine starts. Before you buy, lay that pile out by thickness and compare it with the rating in the manual, and the wood chipper vs chainsaw question will have a clear answer for your yard. When you are ready to buy, my roundup of the best wood chippers overall lists nine picks for branches and yard waste.

Frequently Asked Questions

What to do with tree branches after cutting?

After cutting, tree branches go one of two ways: thick wood is sawn into lengths for firewood, and thin wood within your chipper’s rated branch diameter is chipped into mulch. Wood thicker than that opening goes to a larger machine or a professional, never into a small chipper by force. Keep chips away from trunks and drip lines when you spread them.

How to chip branches without a chipper?

You cannot chip branches without a chipper, because a saw, loppers or a pruner cut wood into pieces and do not turn it into chips. What those tools can do is cut the branches to shorter lengths, so thick wood becomes firewood and thin wood is easier to carry. For real chips, use a chipper that suits the branch size, or a larger rental machine with its own manual.

What should you not cut with a chainsaw?

Do not cut anything at or above shoulder height, anything from a ladder or a roof, or any tree or limb that touches or sits near a power line. Do not cut wood that hangs, tangles in other branches or bends under tension, because it can lash out with extreme force. Those jobs go to a professional, or to the utility when a power line is involved.

Are wood chippers safe to use?

Wood chippers are safe to use only when you follow the exact manual and keep your hands, feet and clothing out of the inlet. The machine can draw in a hand or a sleeve faster than anyone can let go, so you stand to the side, feed butt end first and wear eye, ear and hand protection as the manual directs. Never use your hand, foot or any body part to unclog the machine, even after it is shut down.

What is a good wood chipper alternative for tree branches?

A good wood chipper alternative for tree branches is cutting them to size with loppers, a hand saw or a chainsaw and using the wood. Thick limbs become firewood that way, though thin branches stay as brush and give you no chips. Match the tool to the branch and read its manual first.

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.
