I removed the two wheel drive axle from the deere with the intention of using the Jacobson 4wd axle. After a lot of studying the hydraulic diagrams I decided it wasn't possible to drive the 4wd from the deere hydraulics. The Jacobson energizes a solenoid on a main control valve that sends hydraulic fluid at 250 psi to the 4wd valve. Another solenoid on the 4wd valve energizes to allow 4wd in reverse. The Jacobson has a 4 port pump and the Deere only have three. That fourth pump feeds the control valve. I could have put in a rotary flow splitter to feed the control valve and made it work. It woudl have been a mess of hydraulic hoses, I aslo never ran the wheel motors, so I don't know if the leak. I also have wheels for the Deere axle, I;d have to buy new ones for the Jacobson. I decided to go the simplified approach and install the Deere axle bushings in the Jacobson shaft.

The shafts of the axle are the same diameter but the hubs attach with a pin on the Jacobson and a snap ring on the Deere. I decided to cut the bushings off and weld the deere axle ends to the Jacobson axle. There was some geometry to work out but I made it work.

Here is the rear of the loader (got ahead of myself)

Original Deere Axle, straight shaft. This axle had a 15/16" pin. The Jacobson had a 1-7/16" pin and had the mount made on the frame.



I don't have a pic of the Jacobson axle, the mounts were at different angles, I had to match the angle of the Deere to the Jacobson. I think I got it all lined up pretty good.
