The differences that matter.

01

Engine 22–55 against PTO 19+

BX52S: 22–55 engine hp. WM-8M: 19 PTO hp minimum, no published maximum.

Sub-compacts under 19 PTO hp fit only BX52S; tractors over 55 engine hp only WM-8M.

02

Gravity against mechanical feed

BX52S is gravity-fed. WM-8M’s feed roller is driven through a gearbox at a fixed 58 ft/min, with a stop control.

WM-8M pulls material in at one set speed.

03

5-inch against 8-inch

BX52S: 5 inches with a 5 × 10-inch opening. WM-8M: 8 inches, full capacity in softwood at 50+ PTO hp.

WM-8M takes larger material on a larger tractor.

04

505 lb against 775 lb

Wallenstein lists 505 lb total; WoodMaxx lists 775 lb hitch weight.

WM-8M needs more lift at 24 inches.
