I just dropped my 2760 off at the shop for some much needed warranty repairs. To my chagrin, the problems were not fixed. The unit has 600 hrs. The left wheel is grabbing and is not as fast and powerful as the right. This makes for a very annoying situation while I'm trying to carry my stripes...not to mention the fact that it is dangerous while backing off the truck or trimming ditchhlines. The problems gets worse the more the system heats up. Dooley Tractor said that they suggest that my hydro filter be changed. IT was changed at 200 hrs; so I did not think that it was neccessary... but, I let them do that anyways. It did not fix the problem(for the second time). What is wrong with my hydraulic system? Also, my relays are shorting out every time it rains. I've already gone through 20 relays in the last year. I noticed that my hydro cooling fan is not working(relay?) since I got the mower back a couple of days ago. Is it okay to run the unit until I can get back up to Dooley(90 miles away)?
