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.

02

20 against 19 PTO hp minimum

WoodMaxx’s MX-8800 manual requires at least 20 PTO hp; the WM-8M page lists 19.

Tractors at 19–20 PTO hp fit only WM-8M.

03

Weight

WoodMaxx lists 775 lb hitch weight for WM-8M; no MX-8800 operating weight is retained.

Ask WoodMaxx for the MX-8800’s complete weight with shaft and oil.

04

$5,890 against $3,690

Observed November 7, 2026. MX-8800 includes a 32-inch Premium shaft.

MX-8800 costs $2,200 more.

Keep these source limits with the decision.

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.

This comparison reuses the manufacturer evidence retained in the product records reviewed November 7, 2026; product pages were not re-fetched on November 9. Document conflicts are kept visible. No field test or manufacturer-approved tractor pairing is claimed.
