LS MT225S · PTO WOOD CHIPPERS
The MT225S has 19.3 PTO hp: just above the retained 19-hp minimum of the WM-8H and WM-8M, but below the 20-hp minimum of WC68 and MX-8800. This makes feed control and complete operating load more useful comparisons than the largest advertised chip diameter.

THE DECISION IN NUMBERS
Numeric checks use 19.3 PTO hp. No finite maximum was found for the WM-8 models or MX-8800; that does not mean unlimited input is approved. Clearing a minimum does not establish full-diameter output or a tractor pairing.
Scroll the table sideways on smaller screens.
| Chipper | Published PTO requirement | MT225S result | Feed or capacity distinction |
|---|---|---|---|
| WM-8H | 19 hp minimum | 0.3 above minimum | Variable hydraulic feed with reverse; operating mass unknown |
| WM-8M | 19 hp minimum | 0.3 above minimum | Fixed 58 ft/min mechanical feed with stop; no powered reverse |
| WC46 | 15–30 hp | Inside band; below over-20 threshold | Hydraulic feed; full 4-inch/full-feed condition not met |
| WC68 / MX-8800 | 20 hp minimum | 0.7 below both minimums | Larger nominal openings do not remove the minimum |
WM-8H provides variable hydraulic feed and powered reverse from its own system. WM-8M uses fixed mechanical feed with stop, so its controls do not offer the same response to difficult material. Both clear 19 by only 0.3 PTO hp on paper. The maker associates full 8-inch capability with much higher output and material conditions; the MT225S minimum check is not an eight-inch production claim.
WC46 is inside its 15–30 PTO-hp band here, but 19.3 remains below the over-20 condition for full 4-inch logs at full feed speed. WC68 and MX-8800 do not clear their 20-hp minimums at all. Those distinctions should remain visible even though these tractors are marketed in a similar engine-horsepower class. Compare the actual branch material and feed needs with the maker.
The manual’s 1,323 lb rating is at 24 inches behind the lift point. WM-8M lists 775 lb on the hitch with inclusions unresolved; WM-8H’s 990 lb shipping figure is not an operating load. Obtain shaft-inclusive, filled-system mass and center of gravity before checking lift and ballast. The tractor manual also sets 3,086 lb total permissible mass and separate axle limits; these need actual equipped weights.
The compared hydraulic-feed machines carry their own feed systems, while WM-8M is mechanical. They do not depend on the disputed rear-remote option in the LS documents. The tractor’s independent rear PTO still needs the applicable stationary-use procedure and a correctly sized shaft. Manual p 6-3 specifies rear 540 rpm at 2,580 engine rpm, separate from the 2,800-rpm rated engine speed.
THE SCREEN, WITH ITS LIMITS VISIBLE
No pairing below is manufacturer-confirmed. “Preliminary” still requires implement limits, load center, ballast, hitch geometry and shaft checks.
