I use 61" scag tiger cat. After about 20 minutes the mower will lose power from the left lever. Meaning if you need more push from the left lever on a hill or slope the mower will not climb. The mower still runs and cuts fine going straight. The hydrolic pump was just changed and still did not fix the problem. No shops seem to know the answer. I can't be the only one with this issue. The mower climbed these same slopes the first 3 years. Any ideas are much appreciated.
I'm having the same problem. Dealership doesn't have answers and spent $400 already. Installed new dampeners, belt and changed location of spring. Dealer came out and cut grass long enough to see what it was doing. FRUSTRATING Any Luck?
