SuperHandy vs YARDMAX Log Splitter: 14-Ton GUO084 or 6.5-Ton YS0650?

In the SuperHandy vs YARDMAX log splitter choice, I pick the YARDMAX YS0650 for rounds up to 10 in across and the SuperHandy GUO084 for anything wider, up to its 16 in ceiling. Both take 20.5 in lengths and plug into a 15 A outlet, so the real split is diameter, weight and how much each manual tells you to do. I read a hydraulic splitter’s printed limits the way I read a sprayer’s nozzle chart: the number on the plate is a ceiling, never a target.

SuperHandy vs YARDMAX Log Splitter: Which Fits Your Woodpile?

Choose the YARDMAX YS0650 when your rounds stay under 10 in and you want a two-hand control plus written rules for a stalled or stuck log. Go with the SuperHandy GUO084 when rounds run wider, because its manual allows 16 in across and the maker rates it at 14 US tons against the YARDMAX’s 6.5. For the wider field of home firewood machines, I rank seven picks in my ranking of log splitters.

Two rows decide it: log diameter and rated tonnage, then the controls. Weight and cycle time look comparable and are not, so I treat them as context and never subtract one from the other.

Log Size and Tonnage Rating

Both machines take logs up to 20.5 in long, so length never separates them. Diameter does: the GUO084’s manual table prints 16 in, the YS0650’s prints 10 in. The SuperHandy 14 ton electric log splitter carries a 14 US ton rating and the YARDMAX a 6.5 ton rating with a plus or minus 10 percent tolerance, and both are the makers’ ratings, never a measured force. The GUO084 also meets the VEVOR ELS106S in my SuperHandy against VEVOR splitters comparison.

A ceiling is not a target. Fresh rounds from an orchard removal arrive green, and green wood is normally above 60 percent moisture while seasoned firewood sits below 20 percent (1). Wood with interlocked grain is described as exceedingly difficult to split radially (2), so a twisted fruit-tree round deserves a hard look before it goes on the beam.

Laying a long plum round along the GUO084’s beam, I checked it against the 20.5 in limit and set the squared end against the ram, as its manual asks, before I touched the lever. A round past a maker’s limit goes to a bigger machine. My horizontal log splitter picks rank five machines for wood that lies along the beam.

Winner: the SuperHandy GUO084, because its manual prints a 16 in diameter limit against 10 in.

Moving, Setting Up and Anchoring

The SuperHandy rolls on two 8 in wheels with a handle and a rear support leg, and its manual says the handle and wheels are only for moving it by hand. The YARDMAX rolls on two 7 in rear wheels with a tubular frame handle. The listed weights come from different bases: the manual gives the GUO084 at 126 lb net and the YS0650 at 104.7 lb as product weight, so I do not set one against the other. I compare moving weight and wheels across five machines in my portable log splitter picks.

Rolling the GUO084 across my gravel yard, I felt that net weight at the first soft patch, and I set the support leg down before I let go of the handle. Setting down differs by maker. The SuperHandy manual asks for a level surface, blocked tires and a secure support leg. The YARDMAX manual says to secure it on level ground with two bolts or stakes, which are not included, so I drove a pair of stakes into the yard before the first split.

Every move, clean-up, fluid check and stuck log starts from one shutdown, so here it is once for both machines.

Winner: a tie, because the weight bases differ and each manual sets its own set-down rule.

Controls, Time Limit and Stuck Logs

The controls are where the manuals differ most. The GUO084 has a valve lever with a detent (auto-return) valve, and its manual says to operate the control only with your hand, never your feet. The YARDMAX 6.5 ton electric log splitter uses a ZHB control: the left hand holds the hydraulic lever, the right hand holds a pushbutton, the ram stops when either is released, and it returns only when both are free. My hydraulic log splitter picks cover electric, gas and manual machines, each with its own controls.

On the YS0650 the ZHB control keeps my left hand on the lever and my right on the pushbutton, so neither hand can drift toward the beam while the ram moves. Over a stack of rounds on the GUO084, its auto-return valve brings the ram back by itself, so my eyes stay on the beam until the ram has stopped, and I load the next round only then.

SHOP ON AMAZON

The YARDMAX manual sets a time limit: if a log does not begin to split after 5 seconds, release both controls, wait until the ram has returned and stopped completely, then turn the log 90 degrees to try another direction. If it still will not split, its hardness exceeds the machine’s capacity, and I set the round aside. A forked apricot round is the one I expect to meet that rule. I also set the YS0650 against the hand-pump Sun Joe LJ10M in my Sun Joe and YARDMAX splitters comparison.

Before you touch a stuck log, complete the full shutdown for your splitter in the shutdown box above, and use only the stuck-log method your manual gives. The YARDMAX manual’s steps run in this order: release both controls, wait for the ram to return and stop completely, insert a wood wedge under the jammed log, start the splitter to push the wedge under the log, and repeat with a sharper-sloped wedge until the log is free. It says never to knock a jammed log off with a hand or another object. Complete the full shutdown again before any further hands-on step. For the GUO084, use the shutdown box and the procedure in its own manual.

One person runs the machine. In a Swedish study of hand injuries from powered wood splitters, patients hurt on wedge splitters often named more than one person at the machine as a cause (3), and a clinical case series of disabling hand injuries from log splitters warned of the danger (4).

Winner: the YARDMAX YS0650, because it pairs a two-hand control with a 5 second rule and written stuck-log steps.

First Fill, Oil and the Bleed Screw

The GUO084 ships without hydraulic oil, and its manual says to add hydraulic fluid before first use: 1.6 gal of AW32 or AW46 into a 2.1 gal tank. Before you check or add oil, complete the full shutdown for your splitter in the shutdown box above. Then insert the dipstick until it stops to read the level on level ground, never thread it into the fill neck, and tighten it before you restart the motor and cycle the ram out and back until the motion is smooth. Below 32 F, the manual says Dexron III transmission fluid can be used.

The YS0650 lists 10W AW32 oil, a 0.93 gal capacity and an oil change after every 150 hours of use, with the level between the two dipstick grooves. Its bleed screw is loosened before use and tightened before moving, because skipping that step can blow out the seals.

On the first fill I read the GUO084’s dipstick on level ground before the first start. On a cold morning I check the YS0650’s printed 40 to 100 F operating range before I start it.

Pressurized hydraulic fluid can inject through your skin from a hole too small to see. Never check for a leak with your hand: pass a piece of cardboard or wood over the spot and look for discoloration. If fluid hits your skin, see a doctor at once, even if the wound looks small. Before touching any hose, fitting or cap, complete the full shutdown for your splitter in the shutdown box, including hydraulic pressure relief exactly as your manual describes. Never open the hydraulic oil cap or vent plug while the machine is running or hot.

A literature review of high-pressure injection injuries to the hand describes them as a surgical emergency in which early treatment matters (5), which is why that warning stays blunt.

Winner: the YARDMAX YS0650, because its fill is smaller and its manual prints an oil change interval.

Cords, Power and Safety Rules for Both

Both machines plug into a 120 V, 15 A outlet, so the shed circuit decides where you work. Cord rules differ. For a YARDMAX electric log splitter, the manual allows an extension cord no longer than 30 ft and at least 12 gauge with a 3-prong grounded plug. The SuperHandy manual asks for an outdoor-rated extension cord and a GFCI-protected supply in unavoidably damp locations, so use the gauge and length your manual gives. My electric log splitter picks cover five plug-in models for home firewood.

From my shed outlet, the YS0650’s 30 ft limit decides where I set the work pad, and I keep the cord off the floor where the ram works. Use the grounded supply your manual requires and GFCI protection. If the manual permits an extension cord, use a grounded three-wire cord rated for outdoor use, with the manual’s specified gauge and length. Keep the cord away from moving parts and your feet, and never unplug by pulling the cord.

Never put your hands or feet between the log and the wedge, the ram or any part of the splitter while it moves, and keep your fingers out of cracks that open in the log: they can close suddenly. Load the log by holding its sides, never its ends, and run the control only with your hand. Never tie down, block or bypass a two-hand control. Keep your hands clear during both the splitting stroke and the return stroke.

One person operates the control. That person also loads the log. Never let anyone hold the log while you operate the splitter. Keep children, pets and other people out of the work area: the SuperHandy manual says at least 10 ft (3 m), and the YARDMAX manual says to keep bystanders a safe distance behind the operator and prints no number. No distance makes a work area safe on its own, so keep watching it.

Wear the eye protection your manual specifies, with a face shield where it asks for one, and hearing protection wherever it asks: the SuperHandy manual names goggles or glasses with side shields and ear protection when needed, and the YARDMAX manual recommends Z87 rated glasses. Wear sturdy boots, no loose clothing, jewelry, drawstrings or untied long hair, and gloves exactly as your manual directs.

Set the splitter on firm, level, dry ground outdoors, never on a slope, ice, mud or slippery ground, and never run it in rain or damp conditions. Split one log at a time, with the grain and square-cut ends, within every size limit your manual gives, and check for nails, wire and other foreign objects. Stop at the manual’s time limit rather than forcing a log.

Winner: a tie, because each manual gives its own cord rule, and the one printed for your machine is the one that counts.

Choose the SuperHandy GUO084 If

The SuperHandy GUO084 14 Ton Electric Log Splitter is the one I pick when the wood is wide. My SuperHandy GUO084 splitter review covers that wide-round machine in more detail.

• Wide rounds: your rounds run past 10 in across, up to the 16 in the manual prints.
• Higher rating: you want the maker’s 14 US ton rating rather than 6.5 tons for stubborn limbs.
• Rolling it: you want two 8 in wheels and a rear support leg for setting it down on a gravel yard.
• Skip it if: you lift it alone up steps, or you want a two-hand control and a written 5 second rule from the manual.

Lifting a round onto the GUO084’s beam, I lifted from its sides, never its ends, and I stopped for a break when my back said so.

Choose the YARDMAX YS0650 If

Among YARDMAX models, the YARDMAX YS0650 6.5 Ton Electric Log Splitter is the one I pick when the wood stays small. My review of the YARDMAX YS0650 covers that small-round machine in more detail.

• Modest rounds: your rounds stay under 10 in across and no longer than 20.5 in.
• Written rules: you want a two-hand ZHB control, a 5 second limit and numbered stuck-log steps in the manual.
• Short rounds: you want a return stop that shortens the stroke.
• Skip it if: you split rounds wider than 10 in, or you want the higher 14 US ton rating.

Sliding the return stop in for a short apricot round shortened the ram’s travel, and I made that adjustment only after the full shutdown.

Matching the Splitter to Your Widest Round

Match the machine to the widest round you cut. Under 10 in across, the YARDMAX YS0650 gives you a two-hand control and written rules for a stalled or stuck log. Wider than that, the SuperHandy GUO084 is the machine whose manual prints 16 in and a 14 US ton rating. Either way, read the ceiling on your own plate and keep your hands off the beam while the ram moves. For orchard and yard wood, my SuperHandy vs YARDMAX log splitter answer is the YARDMAX YS0650 up to 10 in and the SuperHandy GUO084 above it. For a ranked list to shop from, my log splitter picks for firewood rank seven machines by log size, power and safety.

Frequently Asked Questions

What is the difference between the SuperHandy 14 ton and the YARDMAX YS0650 log splitter?

The difference between the SuperHandy 14 ton and the YARDMAX YS0650 log splitter is size and rating: the SuperHandy prints a 14 US ton rating and a 16 in log diameter, the YARDMAX 6.5 tons and 10 in. Both take 20.5 in lengths on a 15 A circuit, and the YARDMAX adds a two-hand control and a return stop.

Which handles bigger rounds, the SuperHandy GUO084 or the YARDMAX YS0650?

The SuperHandy GUO084 handles bigger rounds, because its manual allows logs up to 16 in across against 10 in for the YARDMAX YS0650. Both manuals print a 20.5 in length limit, so length does not separate them, and neither machine should ever be forced past its own printed ceiling or time limit.

Do the SuperHandy GUO084 and the YARDMAX YS0650 run on the same household outlet?

The SuperHandy GUO084 and the YARDMAX YS0650 both run on a standard 120 V, 15 A household circuit, according to their manuals. Their cord rules differ: the YARDMAX allows a cord up to 30 ft at 12 gauge or heavier, while the SuperHandy asks for an outdoor-rated cord and a GFCI-protected supply.

Which needs more setup before the first split, the SuperHandy GUO084 or the YARDMAX YS0650?

The SuperHandy GUO084 needs more setup before the first split, because it ships without oil and its manual asks for a 1.6 gal first fill of AW32 or AW46 after assembly. The YARDMAX YS0650 arrives partially assembled, with a bleed screw to loosen before use and two bolts or stakes to buy for anchoring.

Which is lighter to move, the SuperHandy GUO084 or the YARDMAX YS0650?

The manuals do not show which is lighter to move, because the SuperHandy GUO084 lists 126 lb net while the YARDMAX YS0650 lists 104.7 lb as product weight, and the two bases differ. The SuperHandy rolls on two 8 in wheels with a rear support leg, and the YARDMAX on two 7 in rear wheels with a frame handle.

Safety Note: Only an adult who has read the manual and understands the controls should use a log splitter, never a child or anyone tired or impaired. The ram and wedge push with tons of force and can crush or cut off fingers, hands and feet: never put your hands or feet between the log and the wedge, the ram or any part of the splitter while it moves, keep your fingers out of cracks that open in the log, load each log by holding its sides, never its ends, and run the control only with your hand, never tying down, blocking or bypassing a two-hand control. Keep your hands clear during both the splitting stroke and the return stroke. Follow the manual’s unloading sequence; WEN 56207 requires the entire cycle to finish and the ram to retract fully before removing split wood. Never straddle or step over an operating splitter or reach or bend over it to retrieve a log. One person operates the control and also loads the log unless the exact manual explicitly permits a loading helper. Never let anyone hold the log while you operate the splitter. If a loading helper is permitted, wait until that helper has left the operating area and reached the manual’s required clearance before moving the control. Keep children, pets and other people out of the work area, at least the distance your manual prints for that exact model, and stop if anyone comes closer. No single distance is safe for every splitter. Set the splitter on firm, level, dry ground outdoors, never on a slope, ice, mud or slippery ground. Secure it against movement as the manual directs; Yardmax requires blocking the front and back of both wheels. Work in daylight or good artificial light as the manual permits, and keep split pieces cleared away from your feet. Never run an electric splitter in rain or damp conditions. Split one log at a time, with the grain and square-cut ends, within every size and weight limit your manual gives, including any minimum length. Check for nails, wire and other foreign objects. Reject knotted, curved or uneven logs where the manual forbids them; Boss ES7T20 forbids uneven logs, including knotted or curved logs. Stop at the manual’s splitting time limit and follow its procedure rather than forcing the log. Wear the eye protection your manual specifies: Champion calls for ANSI-approved safety glasses, and Boss calls for safety goggles or safety glasses with side shields. Also use a face shield where your manual asks for one, hearing protection with a gas engine or wherever your manual asks, sturdy boots (steel-toed where your manual asks), gloves exactly as your manual directs, and no loose clothing, jewelry, drawstrings or untied long hair. Pressurised hydraulic fluid can inject through your skin from a hole too small to see: never check for a leak with your hand, pass cardboard or wood over the spot instead, and see a doctor at once if fluid hits your skin, even if the wound looks small. Before freeing a stuck log, checking or adding fluid or oil, servicing, cleaning, sharpening, adjusting, moving, towing, storing or leaving the splitter, complete the shutdown for its power type. Electric: release the controls, switch the motor off, wait until every moving part has stopped completely, including the ram and any flywheel, then unplug it from the outlet by the plug. Gas: release the controls or return the hydraulic control lever to neutral as your manual directs, turn the engine off, wait until every moving part has stopped completely, including any flywheel, let the engine and muffler cool, then disconnect the spark plug wire and secure it away from the plug. Manual hydraulic: stop pumping and release the pressure exactly as your manual directs. On every hydraulic splitter, relieve hydraulic pressure as the manual describes before servicing or touching a hose, fitting, cap or the wedge area. Never remove the hydraulic oil cap or vent plug while the machine is running or hot, and never adjust pump or valve pressure settings. Before moving, towing or storing a gas splitter, close its fuel valve where fitted as the manual directs. Free a stuck log only by the manual’s procedure, including its instructions for any powered clearing step, never with your hands. Refit every guard before restarting. Use the grounded supply your manual requires and GFCI protection. If an extension cord is permitted, use a grounded three-wire outdoor-rated cord of the manual’s specified gauge and length. Keep connections away from water, keep the cord clear of moving parts and your feet, and never handle the plug with wet hands or disconnect it by pulling the cord. Refuel a gas splitter outdoors in a well-ventilated area with the engine off and cooled for several minutes, following any longer cooling period in its manual. Keep smoking, flames and sparks away, never overfill the tank, and wipe up spills before starting. Keep the manual’s clearances from surrounding objects and combustible materials. Never run it indoors or in a garage or shed, even with the doors open, because the exhaust contains carbon monoxide. Tow a towable splitter only as its manual describes, with towing chains attached exactly as the manual specifies, and never faster than the speed it prints. Store it dry and out of children’s reach, following the manual’s fuel-storage restrictions; Champion 100236 prohibits storing the unit indoors with fuel in its tank. Follow your manual’s lifting and handling instructions and every printed log-weight limit. Take breaks and stop when you are tired.
