Description

When you’re clearing pastures or maintaining fence rows, the last thing you need is a gearbox that can’t handle the power your tractor puts out. A worn or undersized gearbox will either fail under load or bog down when you hit thick brush and weeds. This 40 horsepower gearbox is built to transfer all that power smoothly from your PTO to the blade spindle, so you can tackle tough cutting jobs without hesitation.

What You’re Getting

1 to 1.47 gear ratio that maintains good cutting speed while providing the torque needed for heavy vegetation
Smooth 1-3/8 inch input shaft works with standard PTO connections on most utility and mid-size tractors
Bevel gear design handles side loads and shock better than straight-cut gears
12-spline output shaft provides secure connection to blade assemblies without slippage
Standard mounting pattern with four 5/8 inch holes on a 6-1/2 inch circle fits most cutter decks

Built for Real Farm Work

This gearbox is designed for 540 RPM operation on rotary cutters and brush hogs used for pasture maintenance, roadside mowing, and brush clearing. Whether you’re running a 5-foot finishing mower or a heavy-duty brush hog, this unit handles the demanding work of cutting through everything from tall grass to saplings and brambles.

Made to Last

The bevel gear design spreads loads more evenly than cheaper alternatives, and the housing is built to handle the vibration and shock that comes with hitting rocks, stumps, and uneven ground. Quality seals keep dirt and moisture out while keeping lubricant in, so it keeps running season after season.

Good to Know

This is a direct replacement unit that bolts right in place of your old gearbox. Make sure to check your blade hub and castle nut when installing—this gearbox uses hub 89754 and castle nut 102241. If you’re replacing a failed gearbox, it’s worth checking the blade balance and spindle condition while everything’s apart.
