THE SHORT ANSWER

Is WM-8H worth a closer look?

The useful distinction is feed control: variable speed and powered reverse give the operator more control over incoming material than the fixed-feed WM-8M. Obtain operating weight before judging the rear load; the published 990 lb figure is shipping weight.

The seller confirms the exact setup, current price and delivery. No field test or manufacturer-confirmed pairing is claimed.

THE BUYING PERSPECTIVE

Know before you order.

  • Current page identifies 19 PTO hp minimum; a lower Specs bullet says 15 hp without basis. Retain 19 for screening and ask WoodMaxx to resolve the discrepancy.
  • Manufacturer introduction claims 4-inch hardwood or 6-inch softwood at 19 PTO hp and full 8-inch capacity at 50 PTO hp. These are manufacturer claims, not tests; 50 is not a published maximum tractor rating.
  • A finite maximum PTO horsepower was not found. Null maximum does not mean unlimited power is approved.
  • Use 540 rpm tractor PTO. The 1,120 rpm figure is flywheel speed.
  • The linked manual gives 6.5 gallons on assembly p20 and 7 gallons on maintenance p29. The page also pairs 38 L with 7 gallons inconsistently. Do not select a convenient value; obtain corrected fill instructions for the delivered machine.
  • No tractor pairing has been approved. Confirm hitch geometry, rear load, front ballast and shaft length.

Operating weight is unverified in the current official product page and linked manual. The page lists 990 lb SHIPPING weight; do not use it as operating weight. Confirm weight with PTO shaft and a filled hydraulic tank.
Hydraulics
Self-contained pump and dual feed motors; no tractor hydraulic connection required. The linked manual gives conflicting hydraulic fill quantities: 6.5 gallons in assembly and 7 in maintenance. Confirm the supplied revision and fill instructions with WoodMaxx. Tractor GPM/PSI requirements do not apply to this feed circuit.
Accessories & setup
Included PTO driveline with shear-bolt protection; confirm delivered shaft version and length. Category 2 needs Cat 1-to-2 bushings; Category 1 quick hitch needs suitable bushings, and named quick hitches may need a special top link. Category 2 quick hitch is excluded by the page.

Specifications are manufacturer-published, not measured by Acreage Equipment. A shipping weight is not treated as operating weight.
