No I don't have any experience with this type of tyranny work If you start your rebuild before I do, start a thread on the rebuild and that way maybe we can help one another and if end up starting mine first I'll do the same. I've attached the manuals I have found so far. Plus partstree.com has a good breakdown as well. ... RZT Service manual.pdf Thank you so much, I really appreciate the manual!

Cub cadet RZT 50 hydrostatic transmission - TractorByNet
September 4, 2008 - I just had this same problem with my Z-Force 50 so I pulled the transmissions and changed the oil and so far it seems to have fix it. But I don't know if it was the oil change or just cleaning all the junk off them. The transmission that was acting up had a lot of stuff packed in around the relief lever.

May 2, 2022 - If it was a Sundstrand hydro from ANY IH hydrostatic Cub Cadet built since 1966, they ALL interchange. ... Thanks for the replies guys. I pulled it out yesterday and I'm going to take it to a place tomorrow to see if they have a match. It will be a used one. That's going to be my first try. If no luck there then I'll probably try to find one like Dr. Evil said. Or try to do a rebuild if I can get the parts.

I’ve got one of my transmissions that will stop working after about 15 minutes of driving it, when it cools off it’ll drive again until it hot. Any suggestions on where to start ? Maybe a seal kit ?

I don’t see a filter on it, I’ll start with pumping out the old fluid and putting in fresh fluid. I figured it’s probably on its way out, buying a used or new one is so dang expensive

r/lawnmowers on Reddit: Picked up a Zero Turn - Cub Cadet 50''. What should I do on this for Maintenance / Worry about?
July 18, 2024 -
Attached a picture to the post. Got this from a friend who was moving. It definitely works as he was using it yesterday morning. 427 hours.
Model is 17AH3AGP709
The deck needs one of the casters welded back on. We had to take the deck off to get it on the trailer. So seems like a good time to sharpen the blades, weld the caster on, check bearings and replace the belt.
I know the hydrostatic transmissions can be a problem. The owners manual says the transmission isn't serviceable. However, it does appear to have a filter on each transmission and the expansion tank. I should be able to pull the filters to drain, replace them and refill via expansion tank with the vents pulled.
Anyone know what I should use for the hydraulic filters?
It does start hard cold and needs to run with choke for a while. The carb is a chinese amazon one and the original is long gone. I might see if the choke lever is bent, probably do a valve adjustment (unless it has hydraulic lash adjusters) and some plugs to try to get it to start better.

Congrats. I prefer to use the oem filters on hydros but I'm sure that it isn't necessary as long as it is a quality can. 15 or 20w 50 if think. The oems have good info on their website for changing the oil and purging,Also filter kits with oil etc. I guess try cleaning the carb you have. What could go wrong?

Transmissions can be serviced but typically need to be taken off machine to change fluid. Buy a tune up kit for engine , and remove plastic cover to clean out grass and leaves to prevent overheating
