TYM T25 · PTO WOOD CHIPPERS
At the T25’s documented 18.3 PTO hp, the first useful comparison is a lighter gravity-feed chipper against a heavier chipper with its own controlled hydraulic feed. The tractor’s listed standard remote does not power WC46’s onboard system, and it cannot help a machine whose minimum is 19 or 20 PTO hp.

BEST MATCHES FOR THE T25
7 of 19 pto wood chippers we track pass the published power, hitch and speed screen. Each still has a detail to confirm with the seller.

THE DECISION IN NUMBERS
Aug 2025 North American T25 scope. Product, dry and shipping weights are different bases; the table does not establish permissible operating load. TFG55’s two manual minimums remain a source conflict even though 18.3 exceeds both.
Scroll the table sideways on smaller screens.
| Chipper | Published power requirement | At 18.3 PTO hp | Feed and mass evidence |
|---|---|---|---|
| TFG55 PTO | 12–30 in table; 15–30 in manual hitch text | Inside both ranges; revision still needs reconciliation | Gravity feed; 346 lb product |
| WC46 | 15–30 PTO hp; over 20 for full 4 in/full feed | Inside range; full-diameter/full-feed condition not met | Onboard hydraulic feed; 587 lb product |
| WM-8H | 19 PTO hp minimum; finite maximum unstated | 0.7 below selected minimum | Hydraulic feed; operating weight unverified |
| MX-8800 | 20 PTO hp minimum; finite maximum unstated | 1.7 below minimum | Hydrostatic feed; 772 lb approximate dry, not operating |
TFG55 uses gravity feeding, while WC46 offers hydraulic infeed with its own pump and reservoir. Their retained manuals list product weights of 346 and 587 lb respectively, a 241 lb difference on those product labels. That comparison is useful for identifying which assembly needs closer load review; it is not a measurement of the complete installed load or a promise that the lighter machine suits every branch.
TYM lists one standard remote valve and separates optional front third-function hardware from that specification. WC46 does not need a tractor rear hydraulic supply for its feed system. The same distinction applies to the self-contained WM-8H and MX-8800 feed systems, but the T25 still falls below their selected 19 and 20 PTO-hp minimums. A spare valve, larger hydraulic total or more engine horsepower does not change those PTO results.
WC46’s manufacturer separates its 15–30 operating range from the requirement for over 20 PTO hp for full four-inch logs at full feed speed. The T25 is below that full-feed condition. TFG55’s five-inch description and 5 × 5-inch opening likewise do not establish output on this particular tractor, species or branch shape. Ask for the manufacturer’s material and feed limits at the verified 18.3 PTO hp before choosing on advertised diameter.
The current brochure’s 1,551.2 lb figure is at the end ball joint; its explicit 24-inch value is 1,229.7 lb. The older manual’s 1,102 lb HITCH row has no stated distance and must not be substituted as though it were directly comparable. Obtain the applicable tractor instructions, each assembled chipper’s shaft-and-fluid weight and its center of gravity, then verify front ballast, axle loading and hitch clearance. MX-8800’s 772 lb dry figure is not a complete operating mass.
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.
