Hydro Drive Issue

[Ohiofarmer]

I have a Great Dane Chariot. There's no specific area for Great Dane so I'm posting my problem here since Danes and Scags are similar. My problem is somewhere in my hydro drive system. On my left side I have power going forward, but almost none in reverse. There are no weird noises or leaking. The Dane has approx 825 hours on it and has been worked hard because most all of my 3 acre yard is on a steep hill. I don't like throwing parts at something with the hopes of fixing the problem. Do any of you have a idea as to whether my problem would be in my drive motor or hydraulic pump? Any help would be greatly appreciated.

reverse it up some ramps so you can get underneath ( not going to be easy )
I then lift the front about 2' on some truck axel stands.
If you want to check the movements of the wheel you will of course have to put the rear on axel stands as well.
If I have to fo that I run it up on the ramps first so I can get decient lifting purchase for the jack.
make sure it is very stable before getting under because they are one heavy mower to get crushed under.
have a close look at all the linkages from the motion control arms to the hydro motor.
Chances it has come loose or worn. Also good chance of debris in there stopping the valve from moving full travel
A lot easier to do without the deck on but that is one hell of a heavy deck to remove & replace.
