Self-powered gas-engine woodchippers — the default category for buyers without a tractor. Ranked from homeowner units up to commercial-grade 8-inch chippers.
Gas-standalone woodchippers have their own gasoline engine built in, so they work without a tractor PTO. That portability and independence is the reason to buy one — if you own a tractor with enough PTO HP, a PTO chipper will give you more capacity per dollar.
MechMaxx dominates this category with five dedicated gas chippers. Woodmaxx has just one (the DC-1260 chipper/shredder). Woodland Mills doesn’t make a gas-standalone unit.
Commercial-grade 7-inch gas chipper powered by a Honda GX engine — the most common serious-work gas chipper in the MechMaxx catalog.

MechMaxx's flagship commercial-grade 8-inch chipper with hydraulic feed and a tow-behind frame.
Entry-level 4-inch gas woodchipper aimed at homeowners clearing small branches and yard debris.
On gas chippers the engine is the dominant driver of service life. Honda GX-series engines are the benchmark — they’re widely serviceable, fuel-efficient, and routinely hit 10,000+ hours on commercial equipment. V-twins deliver more torque but are noisier and parts are less universally stocked. Generic or private-label engines can be fine, but check warranty length and parts availability before buying.
Gas chippers under $2,000 are usually manual-feed — you push branches through by hand. Once you cross the $2,500 mark, self-feeding infeed rollers become standard and are a major productivity upgrade. The MechMaxx DCH7 and up are all self-feeding. The GS650, B150, and DC-1260 are manual.
