Best PTO Wood Chipper for Compact Tractors in 2026

The best PTO wood chipper for a compact tractor is not necessarily the one with the biggest opening. It is the one your tractor can actually power and carry.

For most subcompact tractors with roughly 15–20 PTO horsepower, a 3.5- to 4-inch chipper such as the Wallenstein BX36S or Woodland Mills WC46 is the sensible starting point. Owners with more PTO power can move into 5-inch machines such as the WoodMaxx MX-8500G+ or Wallenstein BX52S.

A 5- or 6-inch opening is only the machine’s maximum capacity. It does not mean a 25 hp tractor can continuously process branches that size.

One other detail causes plenty of confusion: manufacturers do not all quote horsepower the same way. Wallenstein publishes engine horsepower for some models, while Woodland Mills and WoodMaxx publish PTO horsepower. Always compare those numbers with your tractor’s actual PTO output rather than relying only on the horsepower printed on the hood.

Quick recommendations

Tractor PTO hp	Good starting point
About 15–20 hp	3.5–4 in. chipper
About 20–30 hp	4–5 in. chipper
About 30–40+ hp	5–6 in. chipper if the manufacturer’s requirements fit

Your tractor also has to lift and carry the chipper. Three-point lift capacity is useful as an initial check, but it is not the whole story. Chipper weight, hitch geometry, ballast, axle limits and manufacturer guidance all matter.

Best PTO wood chippers for compact tractors

Model	Capacity	Published power range	Feed	Published weight
Wallenstein BX36S	3.5 in.	12–30 engine hp	Gravity	395 lb
Woodland Mills WC46	4 in.	15–30 PTO hp	Hydraulic	550 lb product weight
WoodMaxx MX-8500G+	5 in.	15+ PTO hp	Gravity	Net weight not clearly listed
Farmry WCAP5	5 in. fresh / 4 in. dry	15–45 hp, label unclear	Gravity	412 lb product weight
Wallenstein BX52S	5 in.	22–55 engine hp	Gravity	505 lb
Woodland Mills WC68	6 in.	20–50 PTO hp	Hydraulic	710 lb product weight
WoodMaxx MX-8600	6 in.	15+ PTO hp	Hydrostatic	550 lb

Shipping weight is not the same as implement weight. When checking whether your tractor can lift a chipper, use the actual machine weight rather than the crated freight number.

Wallenstein BX36S: a good fit for smaller tractors

The BX36S is the lightest machine in this comparison. Wallenstein lists a 3.5-inch capacity, Category I mounting, gravity feed and a 12–30 engine-horsepower range.

Its 395-pound published weight is one reason it makes sense for smaller tractors. The tradeoff is gravity feed. Straight branches are simple enough, but forked brush requires more operator involvement than a powered-feed machine.

Wallenstein publishes engine horsepower rather than PTO horsepower for this model. That does not make the specification wrong; it simply means you should also check your tractor’s actual PTO output before buying.

For a subcompact owner processing mostly branches under about 3 inches, the BX36S is one of the more sensible dealer-supported choices.

Woodland Mills WC46: strong choice if you want hydraulic feed

The WC46 is built specifically for smaller tractors. Woodland Mills lists a 4-inch capacity, 15–30 PTO horsepower and self-contained hydraulic infeed.

The manufacturer also gives buyers a useful reality check: full 4-inch material at full infeed speed requires more than 20 PTO horsepower.

That matters if you own something like a John Deere 1025R, which produces 18.2 PTO hp. The tractor falls inside the chipper’s published operating range, but you should not expect maximum-diameter performance at full feed speed.

The manual lists the chipper itself at 550 pounds. Current shipping figures are higher because they include packaging.

Hydraulic feed makes forked and irregular brush easier to process, but the powered roller also creates a serious pull-in hazard. Follow the manufacturer’s operating procedure and keep hands and body out of the hopper.

For owners who want powered feed without moving into a large 6-inch machine, the WC46 is one of the most interesting options here.

WoodMaxx MX-8500G+: a 5-inch opening with realistic power guidance

WoodMaxx deserves credit for explaining what its horsepower numbers actually mean.

The MX-8500G+ has a 5-inch opening and requires at least 15 PTO horsepower, but WoodMaxx says that at the minimum power level you should expect roughly 3-inch hardwood or 4-inch softwood. Full 5-inch capacity requires considerably more power.

That is how buyers should interpret chipper capacity.

An 18 PTO hp compact tractor may be able to operate the machine, but that does not turn it into a full-output 5-inch chipper.

The current product information lists shipping weight but does not clearly separate a net implement weight, so confirm the machine’s actual operating weight before using it to judge three-point compatibility.

This model makes sense for buyers who want a larger opening but understand that tractor power determines how much of that opening they can realistically use.

Farmry WCAP5: budget-focused 5-inch option

Farmry’s WCAP5 is another gravity-feed 5-inch chipper.

The current standalone product page lists:

• 5-inch capacity for fresh or wet wood
• 4-inch capacity for dry wood
• 15–45 hp
• 412 lb product weight
• 464 lb packed shipping weight

There is one reason to double-check before ordering: Farmry’s own pages do not always label the figures consistently. A bundle page lists 464 lb as a net weight, while the standalone page lists 412 lb as product weight and 464 lb as packed weight.

Use the standalone 412-pound figure as the current primary product specification, but confirm it with Farmry before making a final tractor-match decision.

The horsepower figure also deserves confirmation because the main specification table does not clearly state whether its 15–45 hp range means engine or PTO horsepower.

That does not make the WCAP5 a bad option. It simply means the buyer has a little more homework to do.

Wallenstein BX52S: dealer-supported 5-inch machine

The BX52S steps up to a 5-inch capacity while keeping a relatively straightforward gravity-feed design.

Wallenstein lists:

• 22–55 engine hp
• 505 lb total weight
• Category I hitch
• 5 x 10-inch infeed opening

Again, the horsepower figure is engine horsepower. A compact tractor can fall inside that engine range while producing significantly less power at the PTO.

For owners who value dealer support and want a larger machine without moving to a heavy hydraulic 6-inch chipper, the BX52S is worth comparing.

Woodland Mills WC68: 6-inch hydraulic option for stronger compacts

The WC68 is a much more substantial machine than the WC46.

Woodland Mills lists:

• 6-inch capacity
• 20–50 PTO hp
• self-contained hydraulic feed
• 710 lb product weight

The important number is not just the 20 hp minimum. Woodland Mills says full 6-inch material at full infeed speed requires more than 40 PTO horsepower.

That tells you exactly how to shop it.

A tractor with 20 or 22 PTO horsepower may operate the WC68, but it should not be treated as a full-speed 6-inch setup.

A John Deere 1025R, at 18.2 PTO hp, falls below the manufacturer’s minimum and should not be paired with this chipper based on engine horsepower alone.

The WC68 is better suited to larger compact tractors whose PTO output and three-point capacity genuinely match the machine.

WoodMaxx MX-8600: large opening with low minimum PTO requirement

The MX-8600 combines a 6-inch opening with hydrostatic infeed.

WoodMaxx lists a 15+ PTO horsepower minimum and a 550-pound implement weight. The same manufacturer information explains that low-horsepower tractors will have reduced real-world hardwood capacity.

That distinction is important.

A small tractor may be capable of turning the chipper, but maximum opening size and practical working capacity are two different things.

For owners who want controlled powered feed and understand the limitations of running a big chipper on lower PTO horsepower, the MX-8600 is an interesting middle ground.

Which one should you buy?

There is no useful overall winner because these machines serve different tractors.

For a smaller subcompact, start with the Wallenstein BX36S or Woodland Mills WC46.

Choose the BX36S if lower weight and a simple gravity-feed design matter most.

Choose the WC46 if hydraulic feed matters more and your tractor can comfortably handle its additional weight.

For owners who want a 5-inch opening, the WoodMaxx MX-8500G+ has particularly useful manufacturer guidance showing how capacity changes with PTO horsepower.

The Wallenstein BX52S is worth considering if dealer support is important.

If you genuinely have enough PTO power and three-point capacity for a 6-inch machine, compare the Woodland Mills WC68 and WoodMaxx MX-8600.

Do not buy the largest opening your tractor can technically turn. Buy the smallest chipper that comfortably handles the branches you normally process.

How to match a chipper to your tractor

Start with four numbers.

1. Tractor PTO horsepower

Use PTO horsepower rather than engine horsepower whenever the chipper manufacturer specifies PTO requirements.

If the manufacturer uses engine horsepower, keep that specification as published and separately check your tractor’s PTO output.

2. Branch size you actually process

Most homestead cleanup is nowhere near six-inch hardwood.

If most of your pile consists of 1- to 3-inch limbs, a properly matched 4-inch chipper may work faster and more comfortably than an oversized machine that constantly loads the tractor.

3. Implement weight

Check the chipper’s actual product or implement weight.

Do not use the freight or crate weight simply because it is the easiest number to find.

Also remember that a lift-capacity figure higher than implement weight does not automatically mean the combination is approved. Hitch geometry, ballast and axle limits still matter.

4. Gravity or powered feed

Gravity feed is simpler and usually lighter.

Hydraulic or hydrostatic feed is useful for irregular and forked material because the machine pulls branches into the chipper. That convenience comes with additional cost, weight and a powerful pull-in hazard.

Choose the system that matches the material you normally handle.

A few expensive mistakes to avoid

Buying by maximum diameter alone

A 6-inch opening does not mean a small tractor will process 6-inch hardwood efficiently.

Confusing engine hp with PTO hp

A tractor advertised at 25 hp may deliver only around 18–21 hp at the PTO.

Using shipping weight to judge three-point capacity

The crate is coming off before the chipper goes on your tractor.

Ignoring replacement parts

Before buying, check the price and availability of knives, shear bolts, belts and hydraulic components.

Buying instead of renting

If you have one storm-damaged tree pile every few years, renting or hiring the job may cost far less than owning a PTO chipper.

New or used?

A used Wallenstein, Woodland Mills or WoodMaxx can be a smart purchase if you can inspect it in person.

Check:

• flywheel or disc condition
• bearings
• knives and knife bolts
• hopper damage
• PTO shaft
• hydraulic hoses and fittings on powered-feed models
• whether the PTO shaft was cut too short for your tractor

Parts availability matters almost as much as purchase price. A cheap machine that needs unavailable knives is not much of a bargain.

For roughly 15–20 PTO horsepower, start with the Wallenstein BX36S or Woodland Mills WC46.

For a larger compact where a 5-inch opening makes sense, compare the WoodMaxx MX-8500G+ and Wallenstein BX52S.

The Farmry WCAP5 may appeal to budget-focused buyers, but confirm its current weight and horsepower labeling before ordering.

Move into the Woodland Mills WC68 or WoodMaxx MX-8600 only when your tractor’s PTO output, hitch capacity and manufacturer guidance genuinely support a larger 6-inch machine.

The best PTO chipper is not the biggest one you can attach. It is the one your tractor can run comfortably while processing the wood you actually have.
