My riding mower start but it wont move

Is the spark plug wet, or is there fuel leaking from carb.
Check shaft on engine while cranking, does it move.
Also check kill wire on engine.

Check to make sure all your likages are properly conncted, could have loose or broken link.

move blade engage lever back and forth
it may not be returning all the way

Your drive belt is off or slipping.

check the belt tension then check . then check the rod on the rear of the mower to see if the rod you pull when you want to push it is not released

Is the brake sticking. On my craftsman mower there is a bar under the brake pedal that pushes back a lever when starting. And the lever sticks. I have to reach underneath and pull the lever forward and then the mower goes. I haven't found a solution to that yet.

mower wont move

yes it is a bad belt unless it is a hydro-stat(no clutch) you need to look under the mower and see if the belt is on correctly

Make sure that when you check the oil that the mower has sat I say for at least 5mins. Your mower might have an oil sencer. If not I think it might be the coil gettin hot and shorting out.

maybe the safty switch under seat might be starting to go out if that switch doesn't work the blades wont come on at all for safety
