Kubota L3770 Deluxe · PTO WOOD CHIPPERS
At 28 PTO hp and 37 gross hp, the L3770 Deluxe is inside the ranges of the small and mid-size chippers here, and outside the large ones. Woodland Mills WC46 and TFG55 stop at 30 PTO hp, 2 above it. Farmry’s engine-rated WCAP5 stops at 45. WC88’s 35-hp minimum and BX72S’s 50 are out of reach.

THE DECISION IN NUMBERS
Tractor reference: Kubota L3770 Deluxe, 28 PTO hp at 2,600 engine rpm (540 PTO at 2,491) and 37 gross hp (SAE J1995); SAE Category 1; 2,646 lb at 24 in. Capacity conditions are manufacturer statements, not throughput tests.

| Chipper | Published requirement | Result on the L3770 | Capacity note |
|---|---|---|---|
| Woodland Mills WC46 | 15–30 PTO hp; over 20 for full 4-inch at full feed | Inside; 2 under maximum | Clears the full-feed condition by 8 |
| Woodland Mills TFG55 | Up to 30 PTO hp | Inside; 2 under maximum | Gravity feed |
| Farmry WCAP5 | 15–45 engine hp | Inside; 8 under maximum | 5 in. fresh, 4 in. dry |
| Woodland Mills WC68 | 20–50 PTO hp; over 40 for full 6-inch at full feed | Inside (+8) | 12 short of the full-feed condition |
| Farmer-Helper FH-BX42 / FH-BX62S | 15–45 / 25–45 PTO hp | Inside | BX62S 3 above minimum |
| WoodMaxx WM-8M / MX-9900 | 19 / 25 PTO hp minimum | Inside | Full 8-inch stated at 50+ |
| Wallenstein BX36S / BX52S | Up to 30 / 22–55 engine hp | BX36S 7 over: excluded; BX52S inside | — |
| Woodland Mills WC88 / Wallenstein BX72S | 35 PTO / 50 engine hp minimum | 7 / 13 short: excluded | — |
Woodland Mills rates WC46 at 15–30 PTO hp and TFG55 up to 30. The L3770’s 28 is 2 under both. Kubota states that 28 hp at 2,600 engine rpm, where the PTO turns about 4 percent above 540, so the power at 540 is not published. For a maximum, a lower figure at 540 only adds margin. The L3970 Premium, at 30.9 PTO hp, is 0.9 over the same ceilings.
Farmry rates WCAP5 at 15–45 engine hp; the L3770’s 37 gross hp is 8 under. Woodland Mills rates WC46 in PTO hp. Both include the L3770, but on different figures. WC46 adds a hydraulic infeed and Woodland Mills’ full-feed condition; WCAP5 is gravity-fed and lighter. The comparison below sets the two side by side.
WC68 (20–50 PTO hp) includes the L3770 with 8 hp to spare above the minimum, but Woodland Mills ties full 6-inch logs at full feed to over 40 PTO hp, 12 above the L3770. It can be slowed through its hydraulic feed. WC88 (35 minimum) is out of range, as is Wallenstein’s engine-rated BX72S.
At 2,646 lb at 24 inches, the L3770 carries any retained chipper here: WC46 is 587 lb, WCAP5 412 lb with shaft, WC68 747 lb. Front ballast and the complete operating weight with shaft still need checking against the operator manual.
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 Kubota L3770 Deluxe’s 37 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, 2,646 lb, carries the 845-lb BX52RI with 1,801 lb to spare. Wallenstein lists no price; ask a dealer.
