Gas Engine vs PTO Power
Power Source
MechMaxx offers two distinct power systems. The 6-inch model uses a ZONSEN 420cc gas engine with electric start. It includes a 12V battery for easy ignition. You do not need another machine to run it. The 4-inch model is a PTO attachment. It connects to a tractor’s three-point hitch. It draws power directly from the tractor’s engine. This requires a tractor with 18 to 45 horsepower. If you already have a suitable tractor, the PTO option saves the cost of a separate engine. If you lack a tractor, the gas model is your only choice.
Cutting Capacity
The maximum branch diameter each machine handles differs significantly. The 6-inch gas chipper processes wood up to 6 inches in diameter. This allows you to clear larger limbs and small trees without pre-cutting. The 4-inch PTO chipper handles branches up to 4 inches thick. It is better suited for smaller twigs and shrubbery. If your yard has large branches from mature trees, the 6-inch model handles them in one pass. The 4-inch model may require you to cut branches down first. For heavy-duty clearing, the larger capacity is more efficient.
Horsepower
Engine power impacts how smoothly the chipper handles thick wood. The 6-inch model features a 15-horsepower ZONSEN engine. This dedicated power source drives the cutting rotor independently. The 4-inch PTO model does not list a specific horsepower rating. It relies on the tractor’s output, recommended between 18 and 45 HP. While the tractor provides ample power, the gas model’s 15 HP is consistent. You get predictable performance regardless of the tractor’s current load. The dedicated engine ensures the chipper runs at optimal speed for wood processing.
Blade System
Both machines use multiple blades for efficient chipping. The 6-inch gas model uses two double-edge blades and one anvil. The blades are made of A8 alloy steel for wear resistance. It achieves a 20:1 reduction ratio, creating smaller chips. The 4-inch PTO model uses four hardened tooling steel blades on a 26-inch rotor. It cuts wood about nine times per second. The counter knife setting produces shredded material between 3/4 inch and 1.5 inches. The PTO model may produce finer shreds, while the gas model offers a high reduction ratio.
Mobility
Moving the chipper to different areas depends on its design. The 6-inch gas model has a tow bar and three wheels. It weighs 441 pounds. You can tow it behind a vehicle or push it manually with the wheels. The 4-inch PTO model attaches directly to a tractor. It weighs less and has dimensions of 60 inches long by 58 inches wide. It moves only when the tractor moves. If you need to move the chipper without a tractor, the gas model’s wheels are essential. The PTO model stays with the tractor.
Discharge Control
Both chippers offer precise debris placement. The 6-inch gas model includes a 360-degree rotary discharge chute with an adjustable deflector. You can direct chips in any direction. The 4-inch PTO model also features a 360-degree rotary chute and adjustable deflector. Both allow you to load trailers or piles accurately. The PTO model uses rotor winglets to create air suction, throwing material out efficiently. The gas model relies on its dedicated engine for consistent airflow. Both provide similar control over where the wood chips land.
