| Woodland Mills WC68 | 20–50 PTO hp; over 40 for full feed | Inside; 0.5 short of full feed | Inside; 3.6 short |

| Wallenstein BX52RI / BX72RI | 30–55 / 45–85 engine hp (page); hydraulic feed; 5-in. / 7-in. | BX52RI inside, BX72RI inside the page’s 45, under the manual’s 50 (on 46 engine hp) | BX52RI inside, BX72RI inside the page’s 45, under the manual’s 50 (on 46 engine hp) |
| Farmry WCAP5 | 15–45 engine hp | 1 over (46): excluded | 1 over (46): excluded |
Farmry WCAP5 Pro (5-inch, PTO-rated) and Woodland Mills WC68 (6-inch, self-contained hydraulic feed) both fit the YT347. The comparison below sets them side by side.
Yanmar rates the YT347 at 39.5 PTO hp at working speed and 36.4 with the tractor stopped. A chipper runs with the tractor parked; WC88’s 35 minimum is still met on the lower figure.
Yanmar lists 2,756 lb at 24 inches. WC88 at 900 lb is well under it.
The YM347 has the same 46 gross hp but 35.5 PTO hp, which puts WC88 at its minimum.
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 Yanmar YT347’s 46 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, 2,756 lb, carries the 1,300-lb BX72RI with 1,456 lb to spare. Wallenstein lists no price; ask a dealer.
