The differences that matter.

01

15–45 against 19+ PTO hp

FH-BX42: 15–45 PTO hp. WM-8M: 19 PTO hp minimum, no published maximum.

Under 19 PTO hp only FH-BX42; over 45 only WM-8M.

02

Gravity against mechanical feed

FH-BX42 uses gravity / pinch-and-pull feed. WM-8M drives its feed roller through a gearbox at a fixed 58 ft/min with a stop control.

WM-8M pulls material in at a set rate.

03

4 × 10-inch against 8-inch

FH-BX42: 4 × 10-inch feed capacity. WM-8M: 8 inches (softwood at 50+ PTO hp).

WM-8M takes much larger wood on a larger tractor.

04

About 430 lb against 775 lb

FH-BX42’s manual gives about 430 lb net; WoodMaxx lists 775 lb hitch weight for WM-8M.

WM-8M needs more lift at 24 inches.

Keep these source limits with the decision.

FH-BX42: the current manual gives 15–45 PTO hp; the product page says 16–50 HP without a basis, and the older product-linked manual adds 26 PTO hp for maximum capacity.

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.
