John Deere 4052M · PTO WOOD CHIPPERS
The WC68 minimum is not the disputed point: both 41.2 brochure hydro PTO hp and the unqualified 39.9 book/manual figure are inside its 20–50 band. Their difference matters to Woodland’s separate over-40-PTO-hp statement for full 6-inch logs at full infeed speed. The 4052M also places both BX52S and BX72S inside their engine-power bands, creating a distinct gravity-feed choice.

THE DECISION IN NUMBERS
Brochure-defined hydro reference: 41.2 PTO hp. Alternative 39.9 is unqualified. Engine comparisons use the current U.S. 51-hp label; older manual says 50.8 gross. No diameter or throughput result is guaranteed.
Scroll the table sideways on smaller screens.
| Product / configuration | Published power requirement | Qualified tractor comparison | Decision still needed |
|---|---|---|---|
| WC68 · self-contained hydraulic feed | 20–50 PTO hp | 41.2 and 39.9 are both inside; 41.2 is 8.8 below maximum | 41.2 is above 40; 39.9 is below. Resolve the actual rating before relying on the full-6-inch/full-infeed statement. |
| WC88 · self-contained hydraulic feed | 35 PTO hp minimum | 41.2 is 6.2 above minimum; 39.9 is 4.9 above | Both are below the maker’s over-60-PTO-hp statement for full 8-inch logs at full infeed speed. |
| BX52S · gravity feed, 5-inch rating | 22–55 engine hp | Current 51 engine label is 4 below maximum; manual 50.8 also inside | Compare its 5-inch rating and gravity-feed format with the larger alternatives; do not use PTO hp against this engine band. |
| BX72S · gravity feed, 7-inch rating | 50–85 engine hp | Current 51 is 1 above minimum; manual 50.8 is 0.8 above | The lower-bound margin does not establish full-diameter performance. Confirm material conditions and delivered hitch hardware. |
The WC68 manual specifies 20–50 PTO hp. Both Deere references remain inside that range, so their disagreement does not change the basic power-band result. Woodland’s page adds a separate requirement: over 40 PTO hp for full 6-inch logs at full infeed speed. The brochure’s explicit 41.2 hydro value is 1.2 above 40; the unqualified 39.9 is 0.1 below. Do not round either to the model’s nominal horsepower or declare full capacity from the favorable source alone. A Deere rating matched to the full PIN and a Woodland assessment of the intended wood are needed.
BX52S’s 22–55 and BX72S’s 50–85 ranges are explicitly engine hp on Wallenstein’s U.S. pages. The current 51-hp engine label lies in both; the older manual’s 50.8 gross reference does too. That makes the 4052M a useful point of comparison between their 5- and 7-inch ratings rather than an automatic reason to choose the larger unit. The BX72S sits near the lower engine-power boundary. Its 7×12-inch housing opening does not mean 12-inch round material, and the listed capacity does not supply a tractor-specific species, moisture or feed-rate guarantee.
Both PTO references clear WC88’s 35 minimum, but neither approaches its over-60-PTO-hp condition for full 8-inch logs at full infeed speed. The tractor’s engine label cannot fill that PTO gap. Compare the actual branch sizes and feed-system preference before paying for a larger opening. WC68 and WC88 have their own hydraulic feed systems, so the tractor’s available rear remotes do not determine their feed suitability. BX52S and BX72S use gravity/manual feed. These are equipment differences, not evidence of higher output or easier handling on this tractor.
WC68’s manual lists 747 lb product weight and 842 lb shipping; WC88 lists 900 and 1,054 lb respectively. Those distinct labels should not be mixed with Wallenstein’s 505-lb BX52S and 728-lb BX72S references, whose complete shaft-inclusive operating scope is unconfirmed. Obtain assembled loads and centers of gravity before using Deere’s 2,500-lb lift reference at 24 inches. Confirm the standard 4M’s actual Category 1 geometry and the older limited-hitch wording. BX72S’s current page adds Category II while its manual says Category I; that does not give this tractor a Category II hitch or settle shaft clearance.
Wallenstein’s current pages rate the 5-inch BX52RI (30–55 engine hp, Category I) and the 7-inch BX72RI (45–85 engine hp, Category I and II). 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 4052M’s 51 engine hp is inside the BX52RI’s range on both the page and the manual. It is inside the BX72RI’s range on both the page and the manual. Its published lift at 24 inches, 2,500 lb, carries the 1,300-lb BX72RI with 1,200 lb to spare. Wallenstein lists no price; ask a dealer.
