Transmission oil ?

[LeftTurn]

I have an old RZT50. It has ZT2200 transmissions.

Looking at the service manual (available on the Hydrogear web site) , you need to take the transmissions off of the mower and turn them upside down to change the oil via the filler. That seems to be a lot of work for a transmission oil change.

The service manual says that the units are factory sealed and do not need oil changes. I guess that's why there is no simple way to change oil or drain plug on the unit. Nice design...

I wonder about the risk of taking the units off, changing the oil, and putting them back on would risk more problems that it might avoid?

It seems like the low-end Cub mowers are pretty much disposable - use them for a few seasons and replace. You get what you pay for!

I mowed again and I still think I have a problem my expansion tank was alittle low but I don't think that was my problem my left side hydro feels loose compared to the right side and if I get the mower going straight ahead and let go of left handle tire locks up if I let go of right the right wheel slows down but keeps turning. mower mows ok turns fine left side seems jerky like i have to keep some pressure on handle or wheel locks up.

is there not an adjustment procedure in your owners manual for equalizing steering arms?

I did not get a owners manual. And the arms are the same as far as going its when i let go left one returns quick and wheel locks up right one comes back slow and wheel keeps turning if that makes any since. I did try lifting mower up and pulled hydro release then started mower left wheel turned right wheel did not so I think something has slipped out of adjustment.

The control arms have a gas dampening shock connected to them, maybe one of those are bad, When the control arm is centered i thought the wheel should lock, my 2 cents.

Hi guys I have tried searching but no luck can anyone tell me what type of oil goes in the hydrostat transmissions? I have zforce 48 inch zero turn. I have one lever that is acting weird compared to the other
The fluid is just barely at the bottom of the tank don't even cover bottom.

What does the operator's manual spec for oil?

Ain't no tinkertoy yer playing with. Best get that owners manual and burn some midnite oil. Find your FULL model # and serial # on the machine's ID plate; go to website PDF Manual Web Archive ; enter date and d/l free pdf copy of manual and p/l.
Hydro Oil specs s/b included. and don't run that machine w/o adequate oil in the hydros - a real quick way to trash them for good.

Guys I did find out what was wrong with my mower. There is a strong arm cylinder on each hydrosta motor the one on my left hydro had came off. I think they act as a buffer of some sort it feels normal now that I hooked it back up. Want to thank everyone that tried to help me.
