New Holland WORKMASTER 25S · PTO WOOD CHIPPERS
At 17.2 PTO hp, the 25S can clear a 15-PTO-hp chipper minimum while remaining below a 19-PTO-hp minimum. Its separate 24.7 gross engine hp also falls inside two Wallenstein engine-based bands. That opens different feed and storage choices without establishing maximum-diameter performance or an approved rear load.

BEST MATCHES FOR THE WORKMASTER 25S
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
Engine-based rows use 24.7 gross hp; PTO-based rows use 17.2. Nominal diameter is a separate specification. Wallenstein full operating masses and minimum-power full-capacity results are unverified.
Scroll the table sideways on smaller screens.
| Chipper | Published tractor-power band | 25S numeric check | Practical distinction |
|---|---|---|---|
| BX36S | 12–30 engine hp | 24.7 inside | 3.5-inch nominal diameter; fixed gravity-feed hopper |
| BX52S | 22–55 engine hp | 24.7 inside | 5-inch nominal diameter; folding hopper, dimensions need review |
| WC46 | 15–30 PTO hp | 17.2 inside; below over-20 full-feed threshold | 4-inch nominal diameter; self-contained hydraulic feed |
| WM-8H | 19 PTO hp minimum | 17.2 is 1.8 below minimum | Larger 8-inch nominal opening does not remove the power limit |
The BX36S and BX52S pages explicitly state engine horsepower, so 24.7 is the relevant tractor figure. Their minimums do not promise full 3.5- or 5-inch processing with this tractor. By contrast, the WM-8H’s retained explicit 19-PTO-hp minimum exceeds the 25S output. Do not substitute the larger gross-engine number to clear a PTO requirement.
WC46 carries its own feed pump and reservoir. It therefore does not need the 25S rear-remote kit that the manual restricts on backhoe-capable configurations. The 17.2 PTO rating is inside WC46’s operating band but below its over-20 threshold for full 4-inch logs at full feed speed. Feed control remains useful, but the published diameter is not a throughput forecast.
BX36S has a fixed hopper; BX52S folds, with conflicting published open and folded dimensions that need measurement. Their listed 395 and 505 lb total weights do not confirm complete operating assemblies. WC46’s retained 587 lb product weight also needs the supplied shaft and filled-system basis confirmed. Compare those actual loads with the 25S lift geometry and axle limits rather than subtracting them from 728 lb.
Manual 92157405 covers stationary rear operation on page 6-17 and distinguishes rear PTO from the mid PTO, which requires an occupied seat. Have the applicable manual and delivered controls demonstrated, including parking, neutral positions and wheel blocking; do not bypass the interlock. Rear 540 rpm is specified at 2,933 engine rpm, and a Wallenstein order needs the correct 540-rpm driveline configuration.
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.

Is the WC46’s adjustable hydraulic feed and folding chute worth considering over the BX36S fixed gravity hopper?
