THE BUYING PERSPECTIVE
Know before you order.
- 19 PTO hp is an operating minimum. Manufacturer introduction claims 4-inch hardwood or 6-inch softwood at that power; full 8-inch material is associated with 50+ PTO hp.
- The manufacturer FAQ narrows the full-capacity statement to 8-inch softwood at 50+ PTO hp. Ask about your species and material condition.
- No finite maximum tractor PTO hp is stated in the reviewed sources. Do not turn the 50+ capacity threshold into a hard maximum or unlimited-power approval.
- Fixed 58 ft/min feed with stop; do not describe this as hydraulic, variable-speed or powered-reverse feed.
- Use 540 rpm at tractor PTO; 1,120 rpm describes the flywheel.
- Some sections use copied WM-8H or hydraulic-control wording. Use WM-8M-specific mechanical-feed instructions and obtain the manual for the supplied serial revision.
