WoodMaxx MX-8800 vs WM-8H: hydrostatic feed system or dual hydraulic rollers?
Both advertise an 8-inch capacity, variable feed and powered reverse without tractor remotes. MX-8800 changes the feed-system architecture and oil requirements: it uses a self-contained hydrostatic drive, while WM-8H uses dual hydraulic feed motors and a much larger hydraulic reservoir. The dated price gap is $1,795. Evaluate those equipment and service differences without assuming a higher field output.

WoodMaxx MX-8800: when to shortlist itConsider when the documented hydrostatic layout and conventional-motor-oil service system are useful to you, with at least 20 PTO hp and confirmed complete weight/geometry.
WoodMaxx WM-8H: when to shortlist itConsider when the dual hydraulic feed system meets the intended material needs and its lower observed price matters, after resolving the minimum-power and oil-fill discrepancies.

The differences that matter.
01
Feed architecture
MX-8800: hydrostatic variable-displacement feed drive and an 8-inch infeed roller. WM-8H: self-contained hydraulic pump with dual feed motors / counter-rotating rollers.
Both support operator speed control and reverse. The architecture difference is documented; relative pulling performance, efficiency and maintenance cost have not been tested.
MX-8800: conventional 10W-40 motor oil; nominal 2 quarts and 2–2.5-quart service guidance. WM-8H: hydraulic oil; manual assembly says 6.5 gallons and maintenance says 7.
These are different fluids and reservoir scales. Resolve the WM quantity conflict and MX shipped-fill wording; do not publish one guessed fill instruction.
MX-8800: 20 PTO hp minimum agrees across current page and manual. WM-8H: page headline 19 PTO hp; lower Specs bullet says 15 hp without basis.
At the low end, source precision matters. Do not use the WM 15 claim as a verified PTO minimum or infer a meaningful performance gain from the one-hp headline difference.
The dated observations differ by $1,795. Confirm that the feed-system and service layout differences matter to the work before paying more for the same maximum diameter label.

WM-8H power and hydraulic volume labels conflict; MX fill/downforce statements differ.
Both complete operating weights remain unverified; MX dry and WM shipping numbers are not interchangeable.
The MX product pages and current manufacturer-linked manuals were checked November 7, 2026. Other products retain the check dates shown with their sources and prices. Advice interprets published specifications; no physical comparison test or manufacturer-confirmed tractor pairing is claimed.
