| Wallenstein BX52S | 22–55 engine hp | 10.4 over: excluded | — |

Woodland Mills rates WC68 at 20–50 PTO hp. The M4D-061’s 52, in both the catalog and the M4 sheet, puts it 2 over. WC88 starts at 35 PTO hp and is the Woodland Mills choice here.
WC88 takes 8-inch material and ties full 8-inch logs at full feed to over 60 PTO hp; at 52, slow the feed on the largest logs. BX72S is a 7-inch gravity chipper rated 50–85 engine hp, inside on the M4D-061’s 65.4. The comparison below sets them side by side.
WoodMaxx ties full 8-inch capacity on WM-8M and WM-8H to 50+ PTO hp and on MX-8800/MX-9900 to “50+ HP”. The M4D-061 meets those lines by 2 on PTO power.
The M4’s lower links are listed as Category I/II with telescopic ends. Most chippers here are Category 1 or 1/2; confirm the pins, bushings and stabilizers before mounting.
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 Kubota M4D-061’s 65.4 engine hp is inside the BX72RI’s range on both the page and the manual. Its published lift at 24 inches, 3,307 lb, carries the 1,300-lb BX72RI with 2,007 lb to spare. Wallenstein lists no price; ask a dealer.
