Farmry WCAP5 vs WoodMaxx WM-8M: a 45-engine-hp ceiling or a 19-PTO-hp floor
WCAP5 and WM-8M overlap for most compact tractors, but they are rated on different figures and differ in size and feed. A KIOTI NS4710, at 44.9 gross engine hp and 36.3–36.6 PTO hp, is 0.1 under WCAP5’s engine ceiling and well above WM-8M’s 19-PTO-hp minimum. WM-8M takes 8-inch material with a fixed mechanical feed; WCAP5 is a lighter 5-inch gravity-feed chipper.

Consider WCAP5 for small material on tractors up to 45 engine hpShortlist WCAP5 when the tractor is inside 15–45 engine hp (with Farmry’s confirmation near 45) and branches are mostly under 5 inches fresh.
Consider WM-8M for larger material without hydraulicsShortlist WM-8M when the tractor has at least 19 PTO hp, branches regularly exceed 5 inches and a fixed-rate mechanical feed suits the work.

The differences that matter.
01
Engine ceiling against PTO floor
Farmry’s WCAP5 manual specifies 15–45 engine hp. WoodMaxx lists WM-8M from 19 PTO hp with no stated maximum, and ties full 8-inch softwood to 50+ PTO hp.
A tractor over 45 engine hp is outside WCAP5. WM-8M has no ceiling, but below 50 PTO hp it is short of its full-capacity statement.
WCAP5’s manual lists 412 lb net with the PTO shaft. WoodMaxx lists WM-8M at 775 lb total on the three-point hitch, without stating shaft or fluid inclusion.
WM-8M is nearly twice the rear load; both are well under a 2,493-lb lift at 24 inches.
WCAP5’s capacity is 5 inches fresh and 4 inches dry on the product page; the manual gives a single 5 × 9-inch opening.
Some WM-8M manual sections use copied WM-8H hydraulic-control wording, and its shipping weights conflict (950 against 990 lb).
This comparison reuses the manufacturer evidence retained in the product records reviewed November 7, 2026; product pages were not re-fetched on November 9. WCAP5 uses the Rev 1.5 manual and current product page; WM-8M uses the current product page, its linked manual and WoodMaxx’s FAQ.
