Having trouble with gravely ZT-50 (4-5 years old)had similar problems few years ago and brought to local dealer for repairs but it wouldnt move at all. This time its acting different, I can cut for about 30 minutes and when it gets ready to stop going, the right arm works fine and the left arm moves forward but make whining /straining sound and doesnt work at all; just goes in circles. I can let it cool down and it will work for a little while again.
Dealer claims over the phone that its a $700 part and two hours labor........
Just trying to see other options if someone else had same trouble before I bring into dealer again.
