Just picked up a used M60 tank a couple of weeks ago. I hadnt really used this mower much just yet until last week. While I as in the middle of mowing a yard, the home owner was leaving and since it as close to dark, I turned the blades off and flashed the lights on the mower rather quickly to get his attention. When I went back to start mowing again, the blades wouldnt turn on. The fuses look good, at least the 3 that Ive found do. Would anyone have any idea as to if this would be a relay or what? Pto switch? Blade clutch? Any help would be appreciatted. Thanks in advance.
