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

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.

Exactly as expected. Perfect fit.

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.

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.

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

First off this is sold as a Omni gear gearbox, however when it arrives you will find its a autotech gearbox made in china. I went ahead and installed it because I waited 2 weeks for it to arrive and had fields that needed to be mowed. After 20 minutes of mowing the threads on the end of the blade carrier spline sheared off and the whole blade carrier fell off. After contacting the seller they stated it my mowers fault not being setup right taking zero responsibility for their product. This is the same setup as my old gearbox just falsely advertised and poorly made. Save your money and shop with a company that stands behind their product

It is a solidly built part that easily dropped onto my Bushhog rotary cutter. Had it installed in 30 minutes. Bravo!!!
