| Chipper | Published requirement | On 62 PTO / 70 engine hp | Result |
|---|---|---|---|
| Woodland Mills WC88 | 35 PTO hp minimum; full feed over 60 | Inside; full feed (+2) | Fits |
| WoodMaxx MX-8800 / MX-9900 / WM-8M / WM-8H | 19–25 PTO hp minimum; full capacity at 50+ | Inside; full capacity | Fits |
| Wallenstein BX72S | 50–85 engine hp | Inside (+20) | Fits |
| Wallenstein BX72RI | 45–85 engine hp (page); hydraulic feed; 7-in. | BX72RI inside | Fits on page and manual; hydraulic remote or power pack |
| Woodland Mills WC68 | 20–50 PTO hp | 12 over | Excluded |
| Wallenstein BX52S | 22–55 engine hp | 15 over | Excluded |
| Farmer-Helper FH-BX62S / FH-BX42; Farmry WCAP5 Pro | To 45 PTO hp | 17 over | Excluded |
WoodMaxx MX-8800 (8-inch, 20 PTO hp minimum) and Woodland Mills WC88 (8-inch, hydraulic feed, 35 minimum) are both full-capacity at 62 PTO hp. The comparison below sets them side by side.
Woodland Mills ties WC88’s full-diameter, full-feed capacity to over 60 PTO hp. The 70A clears it by 2; the 75A at 60 is exactly on it.
Case IH lists 2,701 lb at 24 inches behind the pin. WC88 at 900 lb is far under it.
WC68 stops at 50 PTO hp and the Farmer-Helper and Farmry chippers at 45; the 70A is well over all of them.
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 Case IH Farmall Utility 70A’s 70 engine hp is inside the BX72RI’s range on both the page and the manual. Its published lift at 24 inches, 2,701 lb, carries the 1,300-lb BX72RI with 1,401 lb to spare. Wallenstein lists no price; ask a dealer.
