THE DECISION IN NUMBERS
Tractor reference: John Deere 4066R eHydro, open station; Category 1; 2,500 lb at 24 in.
Scroll the table sideways on smaller screens.
| Chipper | Published requirement | On 57 / 52 PTO, 65.9 engine hp | Result |
|---|---|---|---|
| Woodland Mills WC88 | 35 PTO hp minimum; over 60 for full 8-inch feed | Inside; 3 / 8 short of the full-feed line | Fits |
| Wallenstein BX72S | 50–85 engine hp | Inside at 65.9 | Fits |
| WoodMaxx WM-8H / WM-8M / MX-8800 / MX-9900 | 19–25 PTO hp minimum; 50+ for full capacity | Inside; past the 50+ line | 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 | 7 / 2 over | Excluded |
| Farmry WCAP5 / Pro; Farmer-Helper FH-BX; Wallenstein BX52S | To 45 hp or 55 engine hp | Over | Excluded |
Wallenstein BX72S (7-inch) runs 50–85 engine hp; Woodland Mills WC88 (8-inch, hydraulic infeed) starts at 35 PTO hp with no maximum. The 4066R fits both. The comparison below sets them side by side.
Deere’s 4 Series brochure and its May 2026 order book give different PTO ratings for the same tractor; ask which applies to the one on offer. At 57 the 4066R is 7 over WC68’s 50-PTO-hp maximum, and even at 52 it is 2 over, so WC68 is out on both. Neither figure reaches WC88’s over-60 full-feed line.
Deere’s 4 Series brochure lists the 4R with a Category 1 hitch and 2,500 lb 24 inches behind the link arms (3,130 lb at the ends). The heaviest attachment here, WoodMaxx FM-78H at 968 lb, is well under it; check the quoted weight with the shaft and the front ballast the dealer recommends.
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 John Deere 4066R’s 65.9 engine hp 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.
