Best PTO Wood Chippers (2026)

This BILT HARD is built for tractors of 40 to 80 horsepower with a Category 1 three-point hitch. A 30 inch rotor and four blades, each with two usable edges, process branches and wood up to 6 inches in diameter.

The tradeoff is that this is a heavy machine, so check your tractor's lift capacity and rear stability before you buy. A 30 inch rotor stores real inertia, which keeps the knives moving through dense limbs, but it also demands a tractor of enough horsepower to spin it up. Compared with the 4 inch MIVA it handles two inches more, but needs a larger tractor.

Blades with two usable edges mean you can flip them before sharpening. Grease the bearings, check the shaft guard and torque the blade bolts regularly. Before you buy, measure your tractor's lift capacity at the hitch points, because a machine this size can make a smaller tractor light on the front axle; add front ballast if the steering feels vague. Always keep bystanders well back, since a rotor this size can throw chips and splinters a long way.

The Titan attachment is a three-point PTO chipper with a 30 inch oversized rotor, 6 inch timber capacity and compatibility with tractors up to 70 horsepower. A self-feeding chute and an adjustable discharge round out the design.

The tradeoff is that gravity-fed hoppers rely on the operator and the branch weight, so very light or thin material can bounce. It is a more established attachments brand than some newer rivals, which means easier parts and support. Compared with the BILT HARD 6 inch it targets a slightly lower tractor range.

Check shear bolts or slip clutch condition, grease the bearings and inspect the knives before each session. Park on level ground, chock the tractor wheels and set the parking brake before you engage the PTO. It is a sound choice for an owner who wants a name with a dealer behind it, because parts such as knives and shear bolts are easier to source.

The WC68H is a three-point PTO chipper with a hydraulic infeed system and a robust direct-drive design, rated for tractors from 20 to 50 horsepower. It is aimed at landowners, farmers and property managers who want reliable chipping up to 6 inches.

The tradeoff is that hydraulic feed rollers need hydraulic flow from your tractor, so check your remote valve and hose connections. Rollers pull material in at a set rate and can reverse on a stall, which cuts jams and kickback risk compared with gravity feed. Compared with the BILT HARD, it pairs a lower tractor range with a more elaborate feed.

Check hydraulic hoses and fittings for leaks, grease the bearings and keep knives sharp. Confirm that your tractor's remote outlet gives enough flow for the feed rollers, because low flow leads to slow feeding and frustration. When the rollers stall, reverse them, clear the jam with the PTO off and the engine stopped, then restart.

This BILT HARD is a 5 inch PTO chipper for tractors of 15 to 50 horsepower with a Category 1 three-point hitch and a standard 1-3/8 inch, 6-spline, 540 RPM PTO shaft. It processes branches and wood up to 5 inches.

The tradeoff is the 15 horsepower lower end of the range: a tractor at the bottom of the range will bog on dense limbs, so treat 20 to 25 horsepower as a more comfortable minimum for hardwood. Compared with the MIVA 4 inch it adds an inch of capacity at the same tractor class.

Grease the shaft joints, check the guard and torque the blade bolts regularly. On a 20 to 25 horsepower tractor, feed hardwood slowly and let the PTO recover between limbs. Remember that the horsepower range is a guide, and that your tractor's PTO horsepower is lower than its engine rating, often by 15 to 20 percent.

The MIVA processes branches and brush up to 4 inches with a high-inertia rotor and a 4+1 blade system, and it is designed for tractors of 18 to 50 horsepower at 540 RPM. The infeed chute measures 19.7 by 19.7 inches and is gravity-fed.

The tradeoff is capacity: 4 inches covers most orchard and hedge work, but it is not a log processor. It is the smallest machine here, which makes it more suitable for a compact tractor and easier on the lift arms. Compared with the 5 inch BILT HARD it is a step down in capacity for a similar tractor range.

Inspect the shaft guard, grease the joints and sharpen the knives as needed. The compact size also makes it easier to store, and a smaller unit puts less stress on a small tractor's lift arms and rear axle. Keep your feed steady and avoid dropping heavy limbs into the throat all at once.

The SinolinK is a 4 inch PTO chipper for Category 1 three-point tractors from 16 to 45 horsepower with a standard 540 RPM PTO. Its rotor carries four reversible hardened steel knives, and a 20 by 20 inch oversized hopper uses gravity to feed.

The tradeoff is similar to the MIVA: 4 inches is a modest ceiling. Reversible knives give you two edges per knife, which doubles the time between sharpening. A lower 16 horsepower bottom end makes it one of the few options for very small tractors, though such a tractor will struggle with dense limbs.

As with all PTO machines, check the shaft guard and grease the joints. The reversible knives are easy to flip when one edge dulls, which keeps the machine productive between full sharpenings. Keep a spare set of shear bolts in the toolbox.
