I've had my Fasttrak for about three years now and just done routine maintenance. Had an oil sending unit go bad, and it was an easy install.
But tonite I was mowing my 1 acre lot and noticed a whining coming when I had the blades engaged. It changed in pitch with the increase / decrease in RPM, but did not decrease.
I do not know of any fluids that can be checked other than engine oil, which is fine.
Has anyone else experienced this issue, and how did you fix it? FYI, my engine is Kohler Courage 17.
Thx in advance.
