Help with 129 hydro!
Hello all! First off I want to thank you all for the knowledge you have shared. So far I have been able to search and solve all kinds of things on my new to me 129. However, I have a new issue and even after searching I can't seem to come up with what is going on.
I was backing the tractor out of the shed and the ramps I was using broke and it dropped down a foot or so and got hung up on the deck. I had to use a floor jack to raise the back end enough to get it back onto a new board and was able to use the hydro lever to back it the rest of the way out.
When I went to move forward there was a loud grinding sound (which I have never heard before). Afterwards the lever went completely loose and had no resistance when trying to move forward or reverse and it would no longer move. I also have hyrdo lift which is now no longer operating either.
The pin where the shaft meets the pump doesn't appear to be sheared. I pulled the seat/body off and when I spin the shaft by hand it is also turning on the rear of the pump.
I am new to hydros and what I do know I have learned from here. When I move the hydro lever on the steering wheel the linkage all moves and moves the shaft on the side of the hydraulic pump, but it is all completely loose and offers no resistance.
When I push the lever to the forward drive position all the way it will just start to creep forward, nothing in reverse.
I knew my check valves were sticking. I thought maybe when it slammed down it caused them to stick down so I pulled them, soaked them in PB blast and they seem to work pretty well. One is still a little sticky, but I'm not sure how else to free it up.
What else could it be?! We are supposed to get our first snow next week and I'd really like to get the plow hooked up and working before I need it this winter.
