Massey Ferguson MF 4707 · PTO WOOD CHIPPERS
Wallenstein lists BX72S for 50–85 engine hp and Category I and II, and the Massey Ferguson MF 4707’s 70 hp and Category II hitch sit inside both. WoodMaxx’s four chippers fit too; the Category 1-only chippers do not.

THE DECISION IN NUMBERS
Tractor reference: MF 4707 platform (cab 57 PTO hp), October 2025 AGCO sheet; the page and 2024 brochure list 60 PTO hp. Category II; 4,850 lb at 24 in.

| Chipper | Published requirement | On 58 PTO / 70 engine hp | Result |
|---|---|---|---|
| WoodMaxx MX-9900 / MX-8800 / WM-8M / WM-8H | 19–25 PTO hp minimum; 50+ for full capacity; no maximum; Category 1/2 | Inside; 8 over the 50+ line | Fits |
| Wallenstein BX72S | 50–85 engine hp; Category I and II | Inside (15 under; 10 under on the 75 maximum) | Fits |
| Woodland Mills WC88 | 35 PTO hp minimum; Category 1 | Power inside; hitch mismatch | Excluded |
| Wallenstein BX72RI | 45–85 engine hp (page); hydraulic feed; 7-in. | BX72RI inside | Fits on page and manual; hydraulic remote or power pack |
| Farmry WCAP5 | 15–45 engine hp; Category 1/2 | Over | Excluded |
| All other chippers here | To 55 hp or less; Category 1 | Over and hitch mismatch | Excluded |
Wallenstein BX72S (7-inch) lists Category I and II and a published 85-hp ceiling. WoodMaxx MX-9900 (9-inch, hydrostatic feed) lists Category 1/2 and publishes minimums and a 50+ full-capacity line but no maximum. The MF 4707 clears both; the comparison below sets them side by side.
AGCO’s October 2025 sheet gives 58 PTO hp for the platform tractor and 57 for the cab, at the 2,200-rpm rated speed; the current page and 2024 brochure give 60 at 2,000 rpm. No chipper limit here falls between 57 and 60, so the result is the same on all three.
AGCO lists the MF 4700’s rear linkage as ASAE Category II with telescopic ball ends and a Category 2 drawbar clevis. Category 1-only attachments such as Woodland Mills WC88 and Land Pride FM2560 would need bushings or a quick hitch approved in writing; this site screens them out.
AGCO’s October 2025 sheet lists 4,850 lb 24 inches behind the lift point; the 2024 brochure’s 5,291 lb is recorded as a conflict. Every chipper and mower here weighs a fraction of either figure, so power and hitch decide the fit, not lift.
Wallenstein’s current pages rate 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 Massey Ferguson MF 4707’s 70 engine hp is inside the BX72RI’s range on both the page and the manual. Its published lift at 24 inches, 4,850 lb, carries the 1,300-lb BX72RI with 3,550 lb to spare. Wallenstein lists no price; ask a dealer.
