Woodland Mills WC68 vs WC88: six-inch or eight-inch hydraulic feed?
WC88 adds an eight-inch throat height and a belt-driven flywheel, while WC68 stays at six inches and direct drive. The step up raises the operating minimum from 20 to 35 PTO hp and the published product weight from 747 to 900 lb. Start with the diameter and shape of the wood you regularly handle. The larger opening has value only if the tractor and workload justify it; neither machine’s minimum power promises full-size logs at full feed speed.

WC68: when the six-inch opening meets the jobConsider when six-inch material capacity addresses the job, actual PTO output is within 20–50 hp, and tractor load/geometry checks pass.
WC88: when larger material justifies the step upConsider when the 8 x 8-inch throat has a regular use and the tractor can support the documented power and rear load.

The differences that matter.
01
Operating power
WC68: 20–50 PTO hp. WC88: 35–100+ PTO hp; no finite upper number given.
Compare actual PTO output; 100+ must not be turned into either a hard 100 limit or unlimited approval.
WC68: 6-inch diameter; 6 x 8-inch throat; over 40 PTO hp for full 6-inch logs at full feed. WC88: 8-inch diameter; 8 x 8-inch throat; over 60 PTO hp for full 8-inch logs at full feed.
A larger throat and maximum diameter do not promise that a tractor at minimum power will achieve full-size, full-speed feeding.
Consider when the 8 x 8-inch throat has a regular use and the tractor can support the documented power and rear load. Require over 60 PTO hp for the maker’s full-8-inch/full-feed claim; confirm higher-power use.
WC88’s page and current linked manual give different hopper-mouth heights. Both agree on the 8 × 8-inch cutting throat. Confirm external clearance dimensions.
35–100+ PTO hp is preserved as published. The plus sign is neither a hard 100 hp ceiling nor unrestricted high-power approval.
