The differences that matter.
01
Engine ceiling against PTO floor
Farmry’s WCAP5 manual specifies 15–45 engine hp. Woodland Mills lists WC88 at 35–100+ PTO hp and ties full 8-inch logs at full feed to over 60 PTO hp.
A tractor over 45 engine hp is outside WCAP5 whatever its PTO figure. A tractor under 35 PTO hp is outside WC88 whatever its engine figure. A 45-engine-hp tractor with 37.6 PTO hp is at WCAP5’s ceiling and inside WC88.

02
5 inches against 8
WCAP5 has a 5 × 9-inch opening; Farmry’s page gives 5 inches for fresh wood and 4 for dry. WC88 lists an 8-inch maximum with an 8 × 8-inch throat.
WC88 takes much larger material, but near 35–38 PTO hp it is far below its 60-hp full-capacity condition.

03
Gravity feed against hydraulic feed
WCAP5 feeds by gravity with no hydraulic system. WC88 has a self-contained hydraulic infeed that needs no tractor hydraulics.
WC88’s feed can be slowed to suit a tractor near its minimum. WCAP5 has fewer parts to service.
04
412 lb with shaft against 900 lb
WCAP5’s manual lists 412 lb net with the PTO shaft. WC88’s manual lists 900 lb product weight without saying whether the shaft or oil is included.
WC88 more than doubles the rear load. Both are under a 3,177-lb lift at 24 inches; plan ballast on WC88’s complete weight.
05
Category I/II against Category 1
WCAP5’s manual lists Category I/II mounting with Category I quick-hitch mounting. WC88 is Category 1.
On a Category 1 tractor both mount; on a Category 2 tractor only WCAP5 lists the option.
