Wallenstein BX72S vs Woodland WC88: seven-inch gravity feed or eight-inch hydraulic feed
The WC88 adds an 8-inch diameter rating and adjustable hydraulic feeding, but its 35-PTO-hp minimum is separate from the over 60-PTO-hp condition for full 8-inch logs at full feed speed. BX72S instead publishes 50–85 engine hp and a 7-inch diameter. Compare the tractor’s two power ratings, the actual material and the desired feed controls before treating either number as a buying shortcut.

Wallenstein BX72S: when to shortlist itConsider when 7-inch material and gravity feeding suit the job, the 50–85 engine band applies and the delivered hitch/load/shaft discrepancies are resolved.
Woodland Mills WC88: when to shortlist itConsider when 8-inch material or adjustable powered feed is the reason for buying and the tractor’s PTO output and complete-load limits support the selected operating conditions; check over 60 PTO hp if full-diameter/full-feed work is required.

The WC88 gains stated diameter, while BX72S has the longer second opening dimension. Discuss real branch shape with the maker; neither opening area nor its long side is an independent capacity rating.
BX72S: 50–85 engine hp; no full-capacity power threshold established. WC88: 35–100+ PTO hp; over 60 PTO hp for full 8-inch logs at full feed speed.
Compare engine and PTO ratings separately. The plus sign is not a finite 100-hp ceiling or unlimited approval, and the 35-PTO minimum does not deliver the full-feed 8-inch condition.
BX72S: gravity/manual feed; no hydraulic feed circuit specified. WC88: adjustable feed speed/direction with its own pump and reservoir.
WC88 documents powered control without tractor rear remotes. Plan for its onboard fluid and pump/belt service rather than selecting it solely because the tractor has hydraulic outlets.
BX72S: 540 or 1000 rpm PTO input with correct driveline. WC88: 540 rpm tractor input; page flywheel speed over 1100 rpm.
The WC88’s internal speed increase does not authorize a 1000-rpm tractor input. BX72S’s 1000 option also needs its correct shaft; neither speed difference proves higher output.
BX72S: page Cat I/II conflicts with manual Cat I; 19-inch PTO-height units also conflict. WC88: Cat I; page describes adjustable base height 15-5/8 to 21-5/8 inches.
A larger tractor’s hitch and shaft height deserve explicit review. The adjustable WC88 base is a documented setup feature; neither it nor the BX72S page categories approve actual geometry.
Consider when 7-inch material and gravity feeding suit the job, the 50–85 engine band applies and the delivered hitch/load/shaft discrepancies are resolved.
Consider when 8-inch material or adjustable powered feed is the reason for buying and the tractor’s PTO output and complete-load limits support the selected operating conditions; check over 60 PTO hp if full-diameter/full-feed work is required.
BX72S hitch, folded width, PTO-height units and discharge rotation need delivered confirmation.
WC88 page uses 23×27 and 24×28 hopper-mouth dimensions; manual specifies28-3/16×27 H×W. Do not substitute any for the consistent 8×8 cutting throat.
WC88 finite maximum is not established by 35–100+ wording.
