The MechMaxx 6'' E-Start Wood Chipper is a heavy-duty machine designed for homeowners, farmers, and landscaping professionals who need to process large volumes of branches and yard waste. Powered by a ZONSEN 420cc 15hp engine, it can handle wood up to 6 inches in diameter, making it suitable for forestry, orchards, parks, and large residential properties.
Standout features include the upgraded electric start system, which uses a 12V20Ah lead-acid battery to eliminate the hassle of pull cords. The 4-wheel setup with 19-inch rear wheels and foldable 13-inch front wheels, combined with a trailer bar, allows easy towing behind a vehicle. The 360-degree rotating discharge chute and adjustable deflector give you precise control over where the mulch lands.
Build quality is robust, with double-edged A8 steel blades that stay sharp longer and Kevlar belts that resist wear. Safety is prioritized with an emergency stop switch, a limit switch that shuts the engine when chutes are open, and tail lights that sync with your vehicle's brake and turn signals for safe road transport.
A notable drawback is that the advertised 6-inch capacity is based on softwood branches. When chipping dry hardwood, the actual chip size may be up to 20% smaller. The machine is also heavy (639 pounds), so a capable tow vehicle is necessary. The lead-acid battery may require occasional charging if the chipper sits unused.
Overall, the MechMaxx 6'' E-Start Wood Chipper delivers reliable power and convenience for serious yard work. With a 2-year warranty on both machine and engine, it is a solid investment for those who regularly need to reduce large branches into manageable mulch or compost.
Pros
- Powerful 420cc engine chews through branches up to 6 inches with minimal bogging
- Electric start and battery make startup quick and simple
- Four-wheel frame with trailer bar offers stable towing and easy maneuvering
- Double-edge A8 steel blades and Kevlar belts deliver durability and low maintenance
- Multiple safety mechanisms protect the operator during use and maintenance
Cons
- Assembly is required and the unit is very heavy, so plan on having a helper and some mechanical aptitude
- The included documentation lacks a wiring diagram, which can make electrical hookup challenging; contact support if needed
- Performance is optimized for softwood and green branches; dry hardwood may produce larger pieces than advertised
The MechMaxx 6 inch electric start wood chipper is a heavy-duty yard tool built for homeowners, farmers, and horticultural workers who need to process large amounts of branches and brush. Powered by a ZONSEN 420cc 15hp OHV engine, this machine easily chips material up to 6 inches in diameter, making it a strong choice for clearing property or maintaining orchards and parks.
Real-world performance is impressive. One reviewer ran it almost continuously for six hours clearing pine trees and reported that it chewed through everything quickly without losing power. The electric start works reliably, and the 12V battery ensures you are not fighting with a pull cord. The towable design with four wheels and a trailer bar lets you move the chipper easily behind a mower or ATV, and the 360 degree discharge chute gives you precise control over where the mulch lands.
Build quality is a highlight. The double-edge A8 steel blades stay sharp and resist corrosion, while Kevlar belts reduce wear and maintenance. The machine is well engineered with a 48 inch wheelbase for stable towing, foldable front wheels for compact storage, and several safety features including an emergency stop, a limit switch that shuts down the engine when chutes are open, and synchronized tail lights for road use.
There are some drawbacks to consider. The chipper arrives on a pallet and needs assembly, and at nearly 640 pounds it is not a one-person job. A few buyers noted that the manual lacks a wiring diagram, which can complicate hookup, though MechMaxx customer service has been responsive in replacing damaged parts. Also, performance is best on soft or green wood; dry hardwood branches may not be processed down to the same size.
Overall, the MechMaxx B150 is a powerful, well-built chipper that delivers excellent value for large-scale yard work. If you have substantial tree and brush cleanup ahead and want a machine that can handle hours of continuous use, this is a solid investment for both residential and light commercial applications.

Buying Guide: What to Look for in a Hydraulic Feed PTO Wood Chipper
Tractor Compatibility and PTO Horsepower
Not every chipper works with every tractor. The MechMaxx WC68H is designed for 20–50 HP tractors, making it a versatile choice for compact and utility tractors. If your tractor falls outside that range, you may need to adjust your search. Always check your tractor’s PTO output and the chipper’s required input. A mismatch can lead to poor performance or damage. For more on matching equipment to your tractor, see our Property Equipment guide.
Hydraulic Infeed vs. Gravity Feed
Hydraulic infeed systems pull branches in automatically, reducing operator effort and improving safety. The WC68H features a robust hydraulic infeed paired with a direct-drive design that channels PTO power into maximum torque. This means you can feed material continuously without stopping to push. Gravity-fed chippers require manual feeding and can be slower. For large volumes, hydraulic feed is a game changer. If you also use a zero-turn mower, you might appreciate our comparison of mower decks for similar efficiency insights.
Chipping Capacity and Blade Quality
All three MechMaxx models handle up to 6-inch diameter wood. That covers most branches and small trees you’ll encounter on a typical property. Blade material matters: the WC68H uses durable components, while the two E-Start models feature double-edge blades made from A8 steel for corrosion resistance and long life. Kevlar belts on the E-Start models reduce maintenance frequency. For larger properties, a chipper that processes 6-inch material saves time. Our guide on choosing a zero-turn mower also discusses matching equipment to property size.
Portability and Safety Features
If you need to move the chipper around your property, consider wheeled models. The two E-Start chippers come with four wheels, a trailer bar, and a 48-inch wheelbase for stable towing. They also have emergency stop switches, limit switches on the chute, and synchronized tail lights for road safety. The WC68H is a three-point hitch model, so it stays attached to the tractor. Think about how often you’ll relocate the machine. For more on deck size considerations, see our 48 vs 54 inch zero-turn mower article.
Final Thoughts
Choosing the best hydraulic feed PTO wood chipper comes down to your tractor’s horsepower and how you plan to use the machine. For landowners with a 20–50 HP tractor who want a dedicated, heavy-duty attachment, the MechMaxx 6″ 3 Point Hydraulic Feeding PTO Wood is our top pick: its hydraulic infeed and direct-drive design make chipping large volumes effortless. If you prefer a standalone unit that you can tow behind a vehicle or move around independently, the MechMaxx 6” E-Start Wood Chipper with 4-Wheels offers electric start, portability, and the same 6-inch capacity, making it ideal for properties without a tractor or for those who need flexibility. Both models deliver professional-grade results, and with proper maintenance, they’ll serve you for years.
Frequently Asked Questions
What size tractor do I need for a hydraulic feed PTO wood chipper?
For the MechMaxx WC68H, you need a tractor with 20–50 HP and a standard PTO. Smaller tractors may lack the torque to run the chipper efficiently, while larger ones can handle it easily. Always consult the manufacturer’s specifications before purchasing.
Can I use a hydraulic feed chipper with a compact utility tractor?
Yes, many compact tractors fall within the 20–50 HP range. The WC68H is specifically designed for this class. If your tractor is on the lower end, make sure the chipper’s PTO speed matches your tractor’s output (usually 540 RPM).
How does hydraulic infeed compare to manual feeding?
Hydraulic infeed pulls branches in automatically, reducing physical effort and the risk of kickback. It also allows continuous feeding, which speeds up the job. Manual feeding requires you to push each branch, which can be tiring and slower, especially with heavy or tangled material.
Are the MechMaxx E-Start models suitable for commercial landscaping?
Yes, they are built with a 15 HP ZONSEN engine and can handle 6-inch material continuously. The electric start and towable design make them convenient for commercial use. However, for very high-volume processing, the PTO-driven WC68H may offer better longevity since it uses the tractor’s engine. For more on equipment comparisons, see our zero-turn mower buying guide.
