I just bought from a guy the very same exmark Quest and learning about the maintenance and this helped but mine still not cranking . It was cranking fine until the other day while cutting I stopped to move something in the way . I stopped the blades and when I pulled up the brake handle it shut off and came back and wouldn't start back up . the battery test fine and changed fusses . still trouble shooting .
@@MrBillybob57 I would make sure you check all the safety switches to make sure none of them have become non operational. Assuming there is one associated with the brake handle too.
This was helpful but now every time I engage the PYO switch that fuse blows…any ideas? Harness at the PTO has power and PTO switch will turn it on/off.
Did you ever figure out what caused the fuse to blow? I’m having the exact same issue. I replaced the pro clutch figuring it was shorted but same result. At the bottom of the fuse block there is a spade type diode. Mine tested bad, I replaced it, the blades engaged for about three seconds then it blew the fuse and ruined the diode again. I now pulled that diode out, replaced the blown fuse and the blades are working. However I still don’t know what the hell is going on.
