Kubota BX2680 · PTO WOOD CHIPPERS
The BX2680 reaches the published 19-PTO-hp minimum of the WM-8H and WM-8M under either retained Kubota rating, but the rear-load question is unusually important. WM-8M’s listed 775 lb on the hitch exceeds the BX2680’s 680 lb reference at 24 inches; WM-8H’s complete operating mass remains unknown. Clearing the power minimum does not settle either installation.

THE DECISION IN NUMBERS
BX2680 two-range HST, 4WD and ROPS. Current 19.2 PTO hp and older linked 19.5 are both shown; no verified serial cutoff exists. Implement and tractor weights below have different measurement bases. They do not produce a payload allowance or a confirmed pairing.
Scroll the table sideways on smaller screens.
| Chipper | Power screen at 19.2 / 19.5 PTO hp | Published load evidence | Next decision |
|---|---|---|---|
| WM-8M | Both exceed 19 minimum by 0.2 / 0.5 hp | 775 lb on three-point hitch; operating inclusions unspecified | 95 lb above the 680 lb at-24-in tractor reference; obtain an actual load-center and manual-limit assessment |
| WM-8H | Both exceed explicit 19 minimum; lower generic 15-hp page bullet conflicts | 990 lb shipping; complete operating mass unknown | Shipping mass cannot answer the carrying question |
| WC46 | Both inside 15–30 band | 587 lb product weight in retained Rev C manual | Different load and controlled feed; full 4-in/full-feed condition over 20 PTO hp is not met |
| WC68 | Both below 20 minimum by 0.8 / 0.5 hp | 747 lb product weight in retained Rev C manual | Power mismatch remains before any load or geometry assessment |
The 775-versus-680 comparison is a reason to stop and obtain better carrying information, not a calculation of how much the tractor can safely transport. The chipper’s actual center of gravity, hitch position and operating equipment must be evaluated against the BX2680 manual. A quick hitch changes both load position and shaft geometry. WM-8H cannot be treated as the lighter alternative simply because its operating-weight field is unknown; the 990 lb shipping figure includes a different package.
Current BX material gives 23.3 gross engine hp and 19.2 PTO hp; the older linked sheet gives 24.8 and 19.5. Both PTO ratings clear 19 and fail 20. The WM-8H page also contains a generic 15-hp bullet that conflicts with its explicit 19-PTO-hp minimum. Request the actual machine requirements and tractor manual together. Neither a favorable older figure nor a lower unqualified bullet establishes approval for this subcompact.
WM-8M has fixed mechanical feed at a published 58 ft/min with a stop control. WM-8H offers variable hydraulic feed and reverse from its onboard system. Those are different controls, not proof that either will process eight-inch material on a BX2680. The maker associates full WM-8 capacity with much higher PTO power. Ask which branch sizes and feed practices are supported near the minimum, after the load issue is resolved; do not equate the fixed feed-rate figure with measured output.
WC46 offers adjustable hydraulic feed without needing a tractor rear-remote supply. Its 15–30 PTO-hp operating band includes both BX2680 figures, while the over-20 condition for full four-inch logs at full feed speed includes neither. Its 587 lb product figure is also not a complete fit assessment. Compare the delivered assembly, ground clearance and shaft travel with the actual tractor, and keep the 680 lb at-24-inch basis visible throughout the seller inquiry.
