New to skidsteers, purchased this 2001 753G a few months back. Had it out on the first job on Monday and noticed a wheel grind/noise coming from the right side (while sitting in the machine) when under tight turning. It only occurs when doing a zero turn, pushing out on the left lever and right lever in nuetral. I did check the Hydro levels/etc... prior to work on Monday. I did not recheck after, but did not see any leaks.
