Articulate 4 wheel drive cub

[builder]

I’m building an articulate Cub Cadet using parts obtained from salvaged equipment. I need to change rotation on the input shaft of the hydrostatic. Units (2) I know I need to go inside the pump just not sure what to change. I had an expert that was going to help me and a very good friend but I lost him last week after a heart attach. I would like to get this thing done in his honor.

All you have to do for the reversal of the pump is unbolt the charge pump and "flip it over". Pull the two bolts, rotate it, and bolt it back on. Honestly, you should change the seal and o-ring.

Now, with the pump being turned the opposite direction, you may have to "swap sides" on the ring gear so it still goes the right direction.

what about attaching to the back of the front hydro unit to drive the rear unit? This might simplify setting up the controls. My dad bought one that a guy had worked most of it out. The trick is in syncing the two rearends. And plan on a push-pull cable to link the two trunions together.

Thanks for the info i have not been able to get back (work). Never thought about the ring gear. Can this physically be done. In my simple mind i thought that the ring and pinion would be fixed position (only one way to fit)

Yes it can be done. I wouldn't have mentioned it if it was impossible.

Now, I don't know how you are mounting your trans, or what you are doing. It may not need flipped. You will have to figure that out.
