Omni Gear Rotary Cutter 40 hp Gear Box 1 3/8" X 6 Spline Input Shaft

Replaced the gearbox for a wolverine brush cutter. Pretty much a straight swap, input shaft is about a quarter inch longer than original. Just had to drill new holes in the mower. Runs much better than the original. Put typhoon tape on the oil plug! Lost mine within minutes! Just a standard 1/2” pipe male cap

Put this on my Wolverine Bush Skid Bush Hog. Few adjustments to get it to work properly. 1. The drive spline needs cut shorter. I cut it right where the notch in the spline is. That worked good. 2. Gear box is like 1/16- 1/8 lower than the motor. Added washers under the gear box for each bolt and that lined it up perfect. 3. The motor and gear box gears touched upon install. You need about 3/8 space between the gears for the linkage chain to seat properly. I just shimmer the motor back with some washers. Better solution would be to cut out and 1/4 spacer plate to sit between motor and mount or move motor mount back. The factory gear box holes lined up exactly. The blade arm also mounted with no problems. The only thing I might do also is drill a hole in the blade spline for a pin. It comes with a castle nut but isn't drilled to allow a Cotter pin.

It is very well built

Bought as a replacement on a 72” Wolverine auction bought brush cutter for skid steer. Two issues, input shaft had to be cut approx 2 1/2” and had to shim hydraulic pump back 3/8” . All together now and seams to work fine.

Worked perfectly for replacing gearbox on a 5ft modern ag bush hog. Will update further once we put it to use.

Rebuild a brush cutter. The gearbox has been holding up great.

Exactly as expected. Perfect fit.

This gear box is superior to the original that came with the John Deere mower when it was new.
