Key takeaways
- Horizontal and vertical operation: Dual-position splitters let you stand and push a log up onto a beam, or split heavy rounds vertically without lifting them. The Champion 27-ton is described as a dual-position value.
- Log length capacity: Champion’s 37-ton lists logs up to 24 inches. Match it to the lengths you cut.
- Auto-return valve: Retracts the wedge automatically so you can keep your hands free to load the next piece. Champion’s 25-ton lists one.
- Towing: Larger models are built to be towed. The 40-ton PRO is described as tow-rated to 70 mph, which suits people who move between work sites. Check the maker’s towing instructions and local road rules before towing.
- Warranty and support: Champion lists a 2-year limited warranty and support on the 25-ton. One reviewer rates the NorthStar 37-ton and Champion 40-ton highly for warranty coverage.
- Wedge options and log cradles: Four-way wedges and log catchers can improve productivity.
For most homeowners splitting a few cords of mixed wood each year, a 25 to 27 ton gas log splitter such as the Champion 25-ton or 27-ton or the Troy-Bilt 27-ton is the practical middle choice, while serious firewood producers working with dense hardwood are pointed toward 35 to 40 ton machines such as the Champion 40-ton, Generac 35-ton or NorthStar 37-ton, and occasional users with softwood can manage with a compact 6.5 to 7 ton unit. Tonnage, engine size, cycle time and the maximum log length should line up with the wood you actually split.
Gas log splitters use a small engine to drive a hydraulic pump, which pushes a wedge through the log or pushes the log into a fixed wedge. They are the standard choice for people who split large volumes, work away from an electrical outlet or deal with hard, knotty wood. Roundups published in 2026 by outlets such as Peggy O’Mara, Wood Splitters Direct and Cut The Timber repeatedly feature Champion, and also name SuperHandy, Landworks, Troy-Bilt, Generac, Yardmax, NorthStar, Full Boar and WEN. Because many of those are affiliate-style roundups, this guide attributes specs to the makers or reviewers and avoids quoting prices.

How to Choose Tonnage
Tonnage describes the maximum force the cylinder can apply. Bigger numbers help with larger diameters, knots and dense species such as oak, hickory and maple. Reviewers commonly advise matching tonnage to wood species rather than buying the biggest unit. Softwoods such as pine and spruce split easily and can be handled by smaller machines. Seasoned, straight-grained hardwood is manageable with 20 to 27 tons. Green, knotty or large-diameter hardwood is where 35 to 40 tons is useful. Buying more than you need adds weight, noise and cost, while buying too little slows every round and can stall on tough pieces.
Engine Size and Cycle Time
Engine displacement affects how well the pump holds up under load. Larger engines such as the 338cc units in Champion’s 37-ton and 40-ton models give more reserve. Cycle time is how long the ram takes to move out and back. A slower cycle, such as the 16 seconds listed for the 37-ton, means more waiting if you process many logs, while the 40-ton PRO’s reported 11.3 seconds speeds production. For a few cords per year the difference is minor. For 20 cords or more, as one roundup suggests for the 40-ton, cycle time becomes a real productivity factor.

Safety and Care
- Read the owner’s manual completely before first use and follow all warnings.
- Wear eye protection, hearing protection, gloves and sturdy boots. Keep hands clear of the wedge and beam during operation.
- Operate only on level ground and outdoors; engines produce carbon monoxide, so never run one in a garage or enclosed space.
- Use the controls as intended and never bypass safety features or remove guards.
- Keep bystanders and pets away, since splitting can throw wood and splinters.
- Check hydraulic oil level, engine oil and fuel before each session, and store fuel according to the maker’s instructions and local rules.
- Follow the manual for transport and towing, and allow the engine to cool before storage.
Pick X If… Decision Table
| If you… | Pick |
|---|---|
| Split a couple of cords of softwood a year | WEN 6.5-ton or Champion 7-ton class |
| Want a general homeowner machine | Champion 25-ton or SuperHandy 25-ton |
| Need both horizontal and vertical use on mixed hardwood | Champion 27-ton or Troy-Bilt 27-ton |
| Process large volumes of dense hardwood | Champion 37-ton or 40-ton PRO, Generac 35-ton, NorthStar 37-ton |
| Want strong value across tonnage tiers | Yardmax 35-ton or Landworks 20-ton |
| Care most about warranty and engine brand | NorthStar 37-ton or Champion models |
Budget Tiers
Budget: The WEN 6.5-ton, Champion 7-ton, Landworks 20-ton and SuperHandy 20-ton keep the outlay lowest but trade capacity and sometimes support. Mid-range: Troy-Bilt 27-ton and Champion 25-ton and 27-ton cover the typical homeowner. Premium: Champion 37-ton and 40-ton PRO, Generac 35-ton and NorthStar 37-ton add reserve force and faster production but are heavier.
Alternatives to Consider
- Electric log splitters: Quieter and fine for small rounds, they need power access and typically lower force. They suit small yards.
- Kinetic splitters: Use a flywheel instead of hydraulics and are fast on straight-grained logs, though they have different safety considerations.
- Manual maul or hydraulic hand press: No fuel, but physically demanding for large quantities.
- Buying split wood: If you only need a small amount, delivered firewood may cost less than owning a machine.
- Rental: Renting a high-tonnage splitter for a weekend suits one-off projects.
Matching a Splitter to Your Wood Pile
Before buying, estimate how many cords you burn in a season, the diameter of your largest rounds, and the species you cut. A household burning two cords of seasoned oak differs greatly from one splitting a dozen cords of green maple. Measure your typical cut length against the maker’s log capacity, and think about where the machine will be stored, since larger models are heavy and need a flat, dry spot. Consider also how you will move it around the property: wheels, a tow hitch and tongue weight all matter. Finally, look at parts and service availability near you, because a splitter that cannot be repaired locally becomes a long-term burden.
Running Costs and Ownership
Beyond the purchase, a gas splitter needs fuel, engine oil, hydraulic fluid and occasional filter changes. Larger engines burn more fuel but finish sooner, so the difference is often small per cord. Winter storage matters: stabilize or drain fuel as the manual advises, keep the unit under cover, and protect the hydraulic hoses from cracking. Owners who split only a weekend each fall may find a rental or a smaller machine more sensible than a large unit that sits idle.
Frequently Asked Questions
How many tons do I need to split firewood?
For softwood and small rounds, around 6 to 20 tons may do. For mixed hardwood, 25 to 27 tons is a common middle ground. For large, green or knotty hardwood, many reviewers point to 35 tons or more.
Is a vertical or horizontal splitter better?
Horizontal operation is comfortable for smaller logs you can lift onto the beam. Vertical operation helps with heavy rounds you would rather roll into place. Dual-position models offer both.
Does engine size matter more than tonnage?
They work together. A larger engine drives the pump more strongly and holds up better under load. A big tonnage rating with a small engine can still feel sluggish, so compare both along with cycle time.
Can I use a gas log splitter in a garage?
No. Engines produce carbon monoxide and should only run outdoors with good ventilation. Follow the manual and keep the splitter away from buildings and flammable materials.
How often does a gas log splitter need maintenance?
Check engine oil, hydraulic fluid, fuel and fasteners before each use. Follow the maker’s schedule for oil changes, filter replacement and winter storage. Regular upkeep extends engine life and reduces breakdowns.
Are cheap log splitters worth it?
For occasional use on softwood they can be adequate. For regular hardwood splitting, a stronger engine, longer log capacity and better warranty usually pay off. Compare support and parts availability before choosing the lowest tier.
