WoodMaxx MX-8800 vs WM-8M: hydrostatic or mechanical feed at 8 inches
Both are 8-inch WoodMaxx chippers on Category 1/2 hitches, with full capacity tied to 50+ hp. The MX-8800 adds adjustable hydrostatic feed and reverse for $2,200 more. A Kubota L2502 gear (19.8 PTO hp) fits WM-8M only; above 20 PTO hp both fit.

The differences that matter.
01
Hydrostatic against mechanical feed
MX-8800’s self-contained hydrostatic feed has operator-adjustable speed and reverse. WM-8M drives its feed roller mechanically through a gearbox at a fixed 58 ft/min, with a stop control.
MX-8800 adjusts to the material; WM-8M feeds at one speed.
MX-8800: WoodMaxx ties full 8-inch capacity to “50+ HP” without repeating whether that is PTO power; the 20-PTO-hp minimum is explicit.
WM-8M: WoodMaxx’s FAQ narrows the full 8-inch claim at 50+ PTO hp to softwood; page sections disagree on whether the standard or Premium shaft ships.
