It is rather easy to change once you locate it. The positive cable goes from the battery to the solenoid. There will be two large posts on the solenoid and one or two smaller posts on the solenoid. Just remove the wires and put them back on the new one in the same location. Make sure you remove one of the battery cables from the battery before you start so you don't short anything out. Once your done make the last thing hooking that cable back to the battery.
It is typically close to the selenoid. It is inline with the wiring.
Positive battery cable, (red) goes to it and again comes off it and to the starter. Just follow the red battery cable. usually under the hood.
First you check to see if the selenoid is working by turning the ignition key and listen for a click on the selenoid if you hear a click the selenoid is probably working. Then you take a test light and put it on one side of the large wire which should have power if you turn the key on. If you have no power on either side your trouble is before the selenoid. If you have power on one side but not the other when you hear the click of the selenoid, when you turn the key on, your selenoid is not working.

Sounds like the starter relay or solenoid is stuck. Check the selenoid - the selenoid might be stuck closed which would cause the starter to turn because the power wouldn't be shut off from the battery. Or it may be the ignition switch is stuck in the start position.

You can lift a riding lawn mower with a car or floor jack in order to change the blades. Simply place the jack under the frame of the lawn mower but away from the blades to lift it. Then, block the mower up using bricks or concrete blocks.
