I have a Huskee riding mower that I can't get to start. I put a new battery in and turned the key and nothing happened. If I turn the key, sit on the seat, step on the brake and short the solenoid I can get the motor to spin. I replaced the key switch but that did not help. Any Ideas?

Check and see if you are getting power at the solenoid when you turn key.If not check out your saftety switches .if power is coming to the solenoid ,and still not cranking replace solenoid,
Luck
