JD Hydro - ramps into pickup

[jenkinsph]

My guess is that the speed is also faster forward than reverse and this would explain the power difference.

There is a ramp inside that is in a port after the pump and if the ramp is installed backwards it changes the fwd & rev direction of the motor.I guess this allows it to be used in different applications. Since the gears are straight cut and not ring and pinion design they are just as strong going in either direction.I have gleened this info from a couple of repair threads at MTF.

I have built a awd tractor and the Hydrogear transaxles are identical units. The front one however is turned around so the input belt would clear the case. This led to it operating in reverse so all I had to do was just make the linkage put the front transaxle in reverse to go forward and vice versa for reverse. This was done under the approval of the tech department and this is exactly how Ventrac manufactures the 3000 series, my axles are identical to what they use.

JENKINSPH I think I am correct on this one ,BUT I have been wrong before reading posts and interpreting them. sorry

I haven't taken mine apart yet but will do this soon as it is about to fail. One would think that if it is setup for lower speed in reverse that it would in turn have a higher torque but it is much weaker. The engine doesn't load down more when backing up so I suspect the fluid is bypassing. I have often thought it is a pedal linkage problem too. Don't know for sure.

My x749 with twin pedals doesn't have any problems and is also faster in forward than in reverse. Power in reverse is the same as forward.

"if" you do succeed in getting the mower up in the truck in revers,
make sure you tie the hood down!!!!!!

LOL.. That sounds like words of experience speaking, maybe?

yea, but thankfully not my own!
