| Chipper | Published requirement | On 77 PTO / 90 engine hp | Result |
|---|---|---|---|
| Wallenstein BX102S | 80–120 engine hp; Category II | Inside at 90 (10 over the minimum) | Fits |
| WoodMaxx MX-9900 / MX-8800 / WM-8M / WM-8H | 19–25 PTO hp minimum; 50+ for full capacity; no maximum; Category 1/2 | Inside; 27 over the 50+ line | Fits |
| Wallenstein BX102RI | 75–120 engine hp (page); hydraulic feed; 10-in. | BX102RI inside | Fits on page and manual; hydraulic remote or power pack |
| Wallenstein BX72S | 50–85 engine hp; Category I and II | 5 over on rated engine (PTO 8 under) | Excluded |
| Woodland Mills WC88 | 35 PTO hp minimum; Category 1 | Power inside; hitch mismatch | Excluded |

Wallenstein states BX72S’s range in engine horsepower. The MF 4709’s 90 rated hp is 5 over and its 95-hp maximum 10 over. Its 77 PTO hp would be inside, but this site screens a limit on the basis the maker states.
Wallenstein’s 10-inch BX102S runs 80–120 engine hp on a Category II hitch only, gravity-fed, at 1,143 lb. The MF 4709’s 90 rated hp and 95-hp maximum both sit inside it, so the 4709 trades BX72S for its larger sibling. Confirm the pins, the PTO shaft for 540 or 1,000 rpm, and front ballast for its weight.
WoodMaxx WM-8M (8-inch, mechanical feed) lists 19 PTO hp minimum and 50+ for full capacity, with no maximum. The comparison below sets it against BX72S, which fits the smaller MF 4707 and 4708.
WoodMaxx publishes minimums and a 50+ full-capacity line but no maximum, so this site does not exclude the 4709. Its 77 PTO hp is 27 over that line; ask which shear bolt or slip clutch the PTO shaft carries and whether it is rated for this tractor.
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.
Wallenstein’s current pages rate the 10-inch BX102RI (75–120 engine hp, Category II). Two hydraulic rollers pull material in at a set rate, and P3 PULSE reverses them when the rotor slows; they need 4–8 gpm from a rear remote or Wallenstein’s PTO-driven power pack. The Massey Ferguson MF 4709’s 90 engine hp is inside the BX102RI’s range on both the page and the manual. Its published lift at 24 inches, 4,850 lb, carries the 1,950-lb BX102RI with 2,900 lb to spare. Wallenstein lists no price; ask a dealer.
