Has anyone experienced this, and do you guys think it is a problem, or fairly normal? I have a Gravely 2348XLP. For probably the last 3 hours, when I first start mowing, it sounds like the left wheel has an intermittent "squeak" while going forward. It seems to happen at the same point as the tire rotates, and goes away after about a minute. Also, as I am stopping and or backing up, the hydraulics seem to wail, instead of moan as usual. The mower has 78 hours on it, the hyd level is good, and I don't see any obvious external obstructions or damage. The overall speed of the mower, or performance between the left and right side do not appear to be affected. I did have to adjust the stops when I first got it because it pulled to one side from the dealer, but it has remained fine since then, and recently it sometimes feels like the right side handle is harder to manipulate. But I can't tell if it really is harder, or just me imagining it. I also checked the tire pressures, and they are identical. Thanks for any input.
