On the line

Several small chippers start at 15 PTO hp. The MT122 is exactly 15.0, so there is no margin for wear or a heavy feed. TFG55 (12 PTO hp on its page) and BX36S (12 engine hp) give real room. The comparison below sets them side by side.

Lift

LS lists 728 lb at 24 inches. WC46 at 587 lb leaves 141 lb; the others are lighter. Add front ballast on a 1,433-lb tractor.

WC46’s 20-hp condition

Woodland Mills ties WC46’s full 4-inch capacity to over 20 PTO hp. At 15, expect to feed slowly.

When the MT125 makes sense

The MT125 (17.2 PTO hp, 24.7 gross) shares the 728-lb lift and clears BX52S on engine power.

THE SCREEN, WITH ITS LIMITS VISIBLE

Compare each configuration.

No pairing below is manufacturer-confirmed. “Preliminary” still requires implement limits, load center, ballast, hitch geometry and shaft checks.

Initial specification screen only. Scroll the table on small screens. Read the product page for every remaining check.
