Woodland Mills WC46 vs WoodMaxx WM-8H: a light 4-inch chipper or an 8-inch one at its 19-hp floor
WC46 and WM-8H both feed hydraulically without tractor remotes, but they are built for different tractors. A KIOTI CS2530H, at 19.3 PTO hp with a 700-lb lift, shows the trade: it is inside WC46’s 15–30 PTO hp with 113 lb of lift to spare, and 0.3 over WM-8H’s 19-hp minimum with no published WM-8H operating weight to check against the lift.

The differences that matter.
01
15–30 against 19 and up
Woodland Mills lists WC46 at 15–30 PTO hp and ties full 4-inch logs at full feed to over 20. WoodMaxx lists WM-8H from 19 PTO hp (a lower Specs bullet says 15 without a basis), with 4-inch hardwood or 6-inch softwood at 19 and full 8-inch capacity at 50.
At 19 PTO hp, WC46 is near its full-feed line and WM-8H is at its minimum, chipping well under its rated size.
WC46’s manual lists 587 lb product weight. WoodMaxx publishes only a 990-lb shipping weight for WM-8H; its mechanical-feed WM-8M is 775 lb on the hitch.
On a 700-lb lift, WC46 has room; WM-8H needs a confirmed operating weight before it can be screened.
WC46 has a self-contained tank and belt-driven pump; WM-8H has a self-contained pump with dual feed motors. WoodMaxx’s manual gives two different fill quantities (6.5 and 7 gallons).
Both let the operator slow the feed on a small tractor; confirm WM-8H’s fill instructions on delivery.
Shortlist WM-8H when the tractor clears 19 PTO hp, WoodMaxx confirms an operating weight the lift can carry, and you expect to move to a larger tractor later.
WM-8H’s page leads with a 19-PTO-hp minimum and has a lower 15-hp bullet without a basis; its manual gives 6.5 and 7 gallons of hydraulic fill.
WC46’s current page lists 648 lb shipping weight and the 2024 manual 693 lb; neither replaces the 587-lb product weight.
