I have had my Timecutter ZX stored for about 2 months now, and found a little plow in my backyard. I went to fire it up yesterday, and it ran but when i tried to drive it the right hydro wouldn't work I could not go straight or turn left. The temp has been in the low 30's. So, I was wondering what the problem could be. Could the right hydro be frozen? Or could it have just completely failed? It wasn't leaking or anything, and it is a sealed unit so you can't check the fluid or change it or anything.
