How to Choose the Best 3 Point Hitch Wood Chipper
1. Tractor Compatibility: HP and Hitch Class
Your tractor’s available horsepower and hitch category are the first filters. A chipper rated for 40-100 HP will not work safely with a 20 HP compact tractor, and a small 4-inch chipper may lack the strength to handle heavy wood behind a 80 HP machine. Always match the chipper’s required PTO horsepower (not engine horsepower) to your tractor’s PTO rating. Most 3 point chippers need at least 15-20 PTO HP for 4-inch models and 30-40 PTO HP for 6-inch models. Check if your tractor uses a Category 1 or 2 hitch; some models like the BILT HARD 6 Inch 3 Point PTO Powered Wood Chipper accept both categories for flexibility.
The PTO shaft speed must be 540 RPM on every model we reviewed. If your tractor has a 1000 RPM PTO, you will need a speed converter. Always confirm your tractor’s PTO output before purchasing.
2. Chipping Capacity and Blade Quality
Capacity is measured by the maximum branch diameter the chipper can handle. A 4-inch chipper suits smaller yards and occasional use, while a 6-inch model handles heavy clearing and storm cleanup. Beyond diameter, look at blade configuration. Hardened steel blades with reversible edges double their life before sharpening. The BILT HARD 6 Inch features a 30-inch rotor with four double-edged blades and a twig breaker bar that prevents long fibers from jamming the intake. Similarly, the MechMaxx 6″ 3 Point Hydraulic Feeding PTO Wood uses a direct-drive design that transfers maximum torque to the cutting drum.
Some chippers include a shredding function with swinging hammers. The Mighty Mac TPH123 uses 24 free-swinging hammers that are reversible four times, allowing you to process leaves and small twigs alongside branches. If you want both chipping and shredding in one attachment, this is a solid choice.
3. Feeding Mechanism: Gravity vs. Hydraulic
Gravity-fed chippers rely on the weight of the branch to pull it into the rotor. They are simpler, lighter, and usually more affordable. A large hopper with a self-feeding design reduces effort. The 4-Inch PTO 3-Point Wood Chipper Attachment features a 20-inch self-feed hopper that uses gravity assist, so you rarely have to push material manually.
Hydraulic infeed systems add a powered roller that grabs branches and pulls them in at a consistent speed. This eliminates the risk of kickback and allows you to feed larger, more awkward pieces without strain. The MechMaxx 6″ includes a hydraulic infeed that works seamlessly with tractors in the 20-50 HP range. If you process a lot of wood or value hands-free operation, hydraulic feed is worth the premium.
4. Safety and Transport Features
Safety should never be overlooked. Look for a transparent debris curtain over the feed hopper to block flying chips and a remote emergency stop button near the operator. The MechMaxx 4” Wood Chipper with Tow Bar has an emergency stop right by the feed port, giving you instant control. For transport, models with a tow bar and wheels (like the MechMaxx 4-inch) can be moved easily around the property without the tractor. Others rely entirely on the 3 point hitch for lifting.
Another convenience is a 360-degree rotating discharge chute. This lets you direct chips into a wagon, truck bed, or pile without moving the whole chipper. Both the 4-Inch Attachment and the MechMaxx 4-inch offer this feature.
Final Thoughts
After evaluating all five models, we find that the BILT HARD 6 Inch 3 Point PTO Powered Wood Chipper stands out for its broad tractor compatibility (40-100 HP) and heavy-duty 6-inch capacity with reversible blades and twig breaker bar, making it ideal for serious land clearing and professional use. For mid-sized tractors and those who value effortless feeding, the MechMaxx 6″ 3 Point Hydraulic Feeding PTO Wood delivers a hydraulic infeed system that handles branches smoothly while producing uniform chips, and it comes with a one-year warranty for added peace of mind. Both chippers offer excellent value for their respective niches, and your choice depends on your tractor’s power and how much wood you process regularly.
Frequently Asked Questions
What HP tractor do I need for a 3 point hitch wood chipper?
For a 4-inch capacity chipper, a tractor with 15-25 PTO HP is sufficient. For 6-inch models, you generally need 30-40 PTO HP or more. Always check the manufacturer’s minimum PTO horsepower requirement, which is different from engine horsepower. The BILT HARD 6 Inch recommends 40-100 HP, while the MechMaxx 6″ works with 20-50 HP.
Can a 3 point wood chipper handle wet branches?
Yes, but wet wood is heavier and may clog gravity-fed chippers more easily. Hydraulic feed systems manage wet branches better because the powered roller maintains consistent intake. For best results, let green wood dry for a few days if possible. The Mighty Mac TPH123 with its shredding hammers can also handle damp leaves and small branches.
How do you maintain a PTO wood chipper?
After each use, clean out any wood debris from the rotor housing and check the blades for dullness or damage. Reversible blades can be flipped, and sharpening should be done with a bench grinder. Lubricate the PTO shaft and bearings per the manual. Store the chipper in a dry shed or cover it to prevent rust. Most models come with a 1-2 year warranty, so register your purchase promptly.
Is a hydraulic feed worth the extra cost?
If you chip frequently or handle large volumes of wood, the hydraulic infeed saves time and reduces operator fatigue. It prevents kickback and allows you to feed branches of varying sizes without stopping. For the occasional user, a well-designed gravity feed with a large hopper works well and costs less. Evaluate your workload to decide.
