John Deere 4044M · PTO WOOD CHIPPERS
The current U.S. page’s rounded engine label is 43 hp; the linked brochure’s hydro row is 33.6 PTO hp, with an unqualified 32.5 elsewhere still unresolved. Wallenstein BX52S uses an engine-hp band, while Woodland Mills WC68 uses PTO hp. Comparing those requirements on their stated bases leaves a useful gravity-feed versus self-contained hydraulic-feed choice.

BEST MATCHES FOR THE 4044M
11 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.
PTO chipperWallenstein
5″ max. chip diameter · 22–55 engine hp · official U.S. page
Confirm the correct attachment and driveline configuration for the tractor’s PTO speed; listed speed options are discrete settings.
PTO chipperWoodland Mills
6″ max. chip diameter · 20–50 PTO hp
Confirm the conflicting tractor specifications in your serial-specific manual; official source values differ.
PTO chipperWallenstein

THE DECISION IN NUMBERS
Engine and PTO ratings are not interchangeable. The 33.6-PTO-hp figure is the labeled brochure hydro reference; 32.5 remains an unresolved, transmission-unspecified source value.
Scroll the table sideways on smaller screens.
| Chipper / feed system | Maker’s horsepower basis | Document-defined comparison | Next decision |
|---|---|---|---|
| BX52S · gravity/manual feed | 22–55 engine hp | 43 engine label lies inside | Confirm the 5-inch model’s workload, exact shaft and complete load. |
| BX72S · gravity/manual feed | 50–85 engine hp | 43 engine label is 7 hp below minimum | Outside the range; do not use 3,130-lb link-end lift to override power. |
| WC68 · self-contained hydraulic feed | 20–50 PTO hp; over 40 for full 6-inch logs at full feed | 33.6 brochure HST is inside, but below the over-40 condition | Discuss actual material and feed preference; no full-diameter output promise. |
| WC88 · self-contained hydraulic feed | 35 PTO hp minimum | 33.6 brochure HST is 1.4 below; unqualified 32.5 also below | Outside the selected reference’s minimum; resolve actual tractor rating before any different claim. |
| WC46 · self-contained hydraulic feed | 15–30 PTO hp | 33.6 is 3.6 above maximum; unqualified 32.5 also above | Outside the stated range under both published references. |
BX52S’s official U.S. page explicitly says 22–55 engine hp. Compare that with the Deere engine label, not its lower PTO number. BX72S starts at 50 engine hp, above the selected 43-hp label despite the 4044M’s larger hitch-lift figures. WC68 and WC88 instead specify PTO horsepower. Keeping these bases visible prevents the engine badge from making WC88 appear to clear its 35-PTO-hp requirement or the PTO rating from misrepresenting the Wallenstein band.
BX52S is a gravity/manual-feed, direct-PTO design; WC68 has its own hydraulic-feed pump and reservoir. Neither requires tractor rear remotes to provide the documented feed function. That leaves a buyer question about branch form, workload and preferred feeding system, rather than whether a 4M rear-valve retrofit is already installed. BX52S’s 5-inch and WC68’s 6-inch labels are maximum capacity references. WC68 specifically requires over 40 PTO hp for full 6-inch logs at full feed, beyond both of the Deere PTO figures under discussion.
Wallenstein lists 505 lb total weight for BX52S without clearly establishing shaft-inclusive operating mass. The retained WC68 manual gives 747 lb product weight. Their 242-lb numerical difference is not a complete operating-load comparison. Ask for each exact configuration’s assembled mass and center of gravity. The tractor’s 2,500-lb reference is at 24 inches; 3,130 lb is at the link ends. Neither automatically rates the chipper load, and the older manual’s whole-machine ballasted-weight limit is not a spare-payload budget.
The Deere brochure identifies independent rear 540 rpm and no economy PTO. Wallenstein’s 540–1,000-rpm product label does not prove this tractor has 1,000-rpm output or that every listed accessory shaft is supplied. Specify the appropriate documented 540-rpm arrangement and ask the seller to verify the delivered shaft. The brochure’s Category 1 label also conflicts with older Deere Limited Category 1 wording. Resolve lift height, pin/top-link dimensions, iMatch or other quick-hitch clearance and shaft geometry for the actual machine before relying on a compatibility label.
Wallenstein’s current pages rate the 5-inch BX52RI (30–55 engine hp, Category I). Two hydraulic rollers pull material in at a set rate, and P3 PULSE reverses them when the rotor slows; they need 3–6 gpm from a rear remote or Wallenstein’s PTO-driven power pack. The John Deere 4044M’s 43 engine hp is inside the BX52RI’s range on both the page and the manual. Its published lift at 24 inches, 2,500 lb, carries the 845-lb BX52RI with 1,655 lb to spare. Wallenstein lists no price; ask a dealer.

Does a 6-inch diameter requirement or adjustable feed justify moving from BX52S to WC68?
