(8 minute mark begins the root cause of the issue ) This video will go through the cranking issue on a Hustler lawnmower where try to start the mower, but the red light dims and nothing but a CLICK!! really gets into the fix of the issue at the 8 minute mark.. but the whole video start to finish Will Be help full.. (May also help problems on other make and model mowers? possibly) , BUT before you go out. and buy a new $285 starter and solenoid, or new battery, two relays, or key switch, this will show a simple NO COST FIX, which is probably the main problem on most peoples mowers.. Granted over time things wear out, and need to be replaced. but this issue is typically caused by a voltage drop due to the safety switches hustler dealers put on after they receive it from the factory.. HOPE this Helps!!! Please LIKE, SHARE, SUBSCRIBE, and Click Notification Bell, THANKS, OBO1 :))
