On WC46’s ceiling

Woodland Mills lists WC46 at 15–30 PTO hp. The mechanical 1M.40 is exactly at 30; the HST is 2.1 under. WC68 (20–50, 6-inch) leaves room on both. The comparison below sets WC46 against WC68.

WoodMaxx and Farmer-Helper

WoodMaxx’s chippers start at 19–25 PTO hp and Farmer-Helper’s FH-BX62S at 25; both 1M.40 versions are inside with full capacity tied to 50+ hp for WoodMaxx.

Engine-rated chippers

The 39.4-hp engine is inside Farmry WCAP5 (to 45) and Wallenstein BX52S (22–55), and 9.4 over Wallenstein BX36S’s 30.

Lift

Massey Ferguson lists 2,535 lb at 24 inches. WC68 at 747 lb is well under it.

Wallenstein hydraulic-feed BXR chippers

Wallenstein’s current pages rate the 5-inch BX52RI (30–55 engine hp, Category I). 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 Massey Ferguson MF 1M.40’s 39.4 engine hp is inside the BX52RI page’s 30–55 but under the 40 that the manual’s table gives for the BX52R, so ask Wallenstein which floor applies to the serial on offer. Its published lift at 24 inches, 2,535 lb, carries the 845-lb BX52RI with 1,690 lb to spare. Wallenstein lists no price; ask a dealer.
