| Woodland Mills WC68 | 20–50 PTO hp; over 40 for full feed | Inside (3 under max); line met | 747 lb |
| Wallenstein BX72S | 50–85 engine hp | Inside (+8.9) | 7-inch |
| WoodMaxx MX-9900 / MX-8800 / WM-8M | 19–25 PTO hp minimum; full capacity at 50+ | Inside; 3 short of 50 | — |
| Wallenstein BX72RI | 45–85 engine hp (page); hydraulic feed; 7-in. | BX72RI inside | Hydraulic feed: 3–6 gpm remote or power pack |
| Farmer-Helper FH-BX62S / FH-BX42; Farmry WCAP5 Pro | To 45 PTO hp | 2 over: excluded | — |
| Wallenstein BX52S | 22–55 engine hp | 3.9 over: excluded | — |

Woodland Mills’ WC88 (from 35 PTO hp) fits with 12 hp of margin. Farmer-Helper’s FH-BX62S stops at 45, 2 under the YM359. The comparison below sets them side by side.
Wallenstein labels BX52S’s 22–55 and BX72S’s 50–85 as engine horsepower. At 58.9 hp the YM359 is past BX52S and inside BX72S.
Yanmar’s YM3 brochure rates the YM359 at 47.0 PTO hp; the current page leaves the PTO cell blank. Confirm with the dealer.
Yanmar lists 2,750 lb at 24 inches. Every chipper here is well under it.
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 Yanmar YM359’s 58.9 engine hp is inside the BX72RI’s range on both the page and the manual. Its published lift at 24 inches, 2,750 lb, carries the 1,300-lb BX72RI with 1,450 lb to spare. Wallenstein lists no price; ask a dealer.
