John Deere 3046R · PTO WOOD CHIPPERS
The WC88 decision changes with the Deere source: 34.1 PTO hp in the current U.S. book is below its 35-hp minimum, while the linked brochure’s 36.6 is above it. Resolve the actual tractor rating before treating WC88 as a candidate. WC68 and MX9900 clear their minimums under either reference, but their diameter labels still do not predict output.

BEST MATCHES FOR THE 3046R
12 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 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 chipperWoodMaxx
9″ maximum chip diameter, inches · 25 PTO hp minimum; maximum not stated
Confirm the complete operating weight; a shipping weight cannot establish the attachment load.
PTO chipperWallenstein
5″ max. chip diameter · 30–55 engine hp · current U.S. page (manual table: 40–55 hp for the BX52R)
Confirm the correct attachment and driveline configuration for the tractor’s PTO speed; listed speed options are discrete settings.
PTO chipperWallenstein
7″ max. chip diameter · 45–85 engine hp · current U.S. page (manual table: 50–85 hp for the BX72R)
Confirm the correct attachment and driveline configuration for the tractor’s PTO speed; listed speed options are discrete settings.
PTO chipperFarmer-Helper
4″ published feed-capacity short side, inches · 15–45 PTO hp in current index-linked manual; older/page conflicts retained
Confirm the complete operating weight; a shipping weight cannot establish the attachment load.
PTO chipperFarmry
5″ max. chip diameter · 15–45 engine hp
Confirm the conflicting tractor specifications in your serial-specific manual; official source values differ.

THE DECISION IN NUMBERS
The book reference is selected for this guide; the conflicting brochure/manual value remains visible because it changes the 35-hp decision. No serial transition or test result is inferred.
Scroll the table sideways on smaller screens.
| Chipper | Published PTO requirement | At book 34.1 / brochure 36.6 | Buyer consequence |
|---|---|---|---|
| WC88 · 8-inch capacity label | Minimum 35; over 60 for full 8-inch logs at full feed | 0.9 below / 1.6 above minimum | Hold until PIN-specific power is resolved; neither meets the over-60 condition. |
| WC68 · 6-inch capacity label | 20–50; over 40 for full 6-inch logs at full feed | Inside range under both; neither exceeds 40 | Candidate for material-specific discussion, not full-diameter/full-feed assumptions. |
| MX9900 · 9-inch capacity label | Minimum 25 | 9.1 / 11.6 above minimum | Capacity label is not equivalent to WC88’s power or production condition. |
| WC46 · 4-inch capacity label | 15–30 | 4.1 / 6.6 above maximum | Outside the stated range under either source. |
The May 2026 U.S. 0291LV book explicitly labels 34.1 as HST PTO hp. The current-linked 3 Series brochure and older North American manual give 36.6. Neither the rounded 45-hp engine label nor the 3046R badge resolves that difference. Ask Deere to identify the applicable rating and manual for the full PIN and transmission. Until that is settled, the selected 34.1 book reference does not clear WC88’s 35 minimum. A larger lift rating or a nearby rounded horsepower number cannot fill the gap.
Even if Deere confirms 36.6 PTO hp, that only changes WC88’s minimum-power screen. Woodland Mills separately requires over 60 PTO hp for full 8-inch logs at full feed speed. WC68 has an over-40 condition for its corresponding 6-inch claim, also beyond both Deere references. MX9900’s 25-hp minimum and 9-inch opening come from another design and do not establish a common throughput test. Compare the actual species, moisture, diameter distribution and workload with each maker’s supportable claim.
WC68, WC88 and MX9900 have their own feed-hydraulic systems. Deere’s standard-seat versus air-ride rear-valve packages therefore do not decide feed compatibility. The tractor still has to meet the chipper’s rear-PTO and hitch requirements, but advertised total hydraulic flow is not additional chipper power. Ask for the exact delivered feed-system equipment and manual revision without treating a tractor rear-remote upgrade as a way to overcome the PTO limit.
The current-linked brochure gives the same 2,200-lb lift reference at 24 inches for the selected 3R models. Retained manual product weights are 747 lb for WC68 and 900 lb for WC88; MX9900’s approximately 816-lb dry reference has a different basis. None is automatically the complete load at the actual center of gravity. Confirm fluids, shaft, hitch accessories and clearance. The older Deere implement-code guidance does not assign these third-party chippers a ballast code or permissible payload.
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 3046R’s 45 engine hp is inside the BX52RI’s range on both the page and the manual. It is inside the BX72RI page’s 45–85 but under the 50 that the manual’s table gives for the BX72R, so ask Wallenstein which floor applies to the serial on offer. Its published lift at 24 inches, 2,200 lb, carries the 1,300-lb BX72RI with 900 lb to spare. Wallenstein lists no price; ask a dealer.
