Thanks. I'll give it a shot..The old belt stretches a touch over time. New belts are stiff. I'd put it around the front hub. Then take a heavy screwdriver and wedge the belt on the rear hub. Rotate the hub with a 1/2" drive socket wrench. I was able to do it myself.
It depends a lot on which Gator your talking about as some are worse than others. My 550 is a 45 minute job in the shop with most of the time spent removing the plastic covers. Definitely something you could not do on the trail unless you happened to bring all the needed tools, a couple extra nuts and bolts cause you're going to drop some in the mud and a six pack... because you're going to need it.
Surprisingly the old belt did not show any damage. The new belt completely got rid of the jerkiness at low speed. My guess is the old belt was just stretched and causing slippage.Did you see a issue with your old belt? Did you use another John Deere belt or aftermarket? My 590 is very jerky as well. With only 20hrs on it. And after sitting for a few days I can’t even get it to shift into gear without reving the engine
