Here the comparison reverses. Farmry’s only gas chipper above 2 inches is the CG84: 4 inches, a 13.5 HP DUCAR DH420 with electric start, $1,999. MechMaxx sells five gas models from the 4-inch GS650 at $1,299 up to the 8-inch CROBA TX1000, including two 7-inch hydraulic-feed machines.
Engine brand is the decisive factor on a gas chipper, because the engine is the part most likely to need service and the hardest to substitute. The MechMaxx DCH7 runs a genuine 22 HP Honda GX — serviceable at any Honda small-engine dealer in the country, with parts off the shelf. The CG84’s DUCAR is a Chinese engine whose parts route back through Farmry or generic import channels.
MechMaxx also offers longer coverage at this tier: 2 years on the DCH7, PowerDCH7, and CROBA TX1000, against Farmry’s flat 12 months on everything. Be aware that MechMaxx’s own consumer models drop to 1 year, so the warranty advantage only applies above the GS650 and B150.
Where the CG84 does answer back is equipment detail: a four-way discharge chute (0/90/180/270°) against the MechMaxx chutes’ more limited rotation, an emergency stop at the feed hopper, and an axle adjustable between 38 and 46 inches. It is the better-appointed machine; the DCH7 is the better-engined one.
