Not to long ago I posted a question about a John Deere 48" Hydro Walk Behind (HD75). I was having problems with the mower getting power to the wheels initially. It began with good power and after an hour or so deteriorated to the point where the right rear wheel had no power at all.
We had the drive belt replaced (turned out the former owner had the wrong one installed). We also had the mower looked over at a dealer, who didn't think the hydro pumps seemed bad, but he didn't actually test them either.
Well today, after mowing the same two yards as before I got 2/3rds done with the second yard and the symptoms returned. As before the right wheel wasn't getting power (but the belt is new and still turning). When I increase the speed at this point, I get the smell of rubber. This is why I was wondering about a pulley possibly being bad. A
Also when I looked at the traction adjustment bolt for the belt it was bouncing around as if it were too loose. I tightened it enough to get it back on the trailer, but was afraid to continue mowing for fear of breaking the belt.
What might cause the loss of power? Is the belt heating up because of the right hydro being bad, or is there another culprit like a stuck pulley?
The dealer agreed to look at it again for free, as all of the initial work was warrantied. I am just trying to educate myself as multiple trips to the dealer are killing me.
As usual, any help is greatly appreciated.
