When turned to the "Off" position, it connects the ignition to the frame ground to turn off the ignition and therefore the spark (fire.)

The kill switch wire is broken or has come loose. If it is a push mower, look at the end of the throttle cable where it touches ground when the lever is in the OFF position. If it is a riding lawn mower, follow the wires from the ignition switch, you will find a disconnection someplace near ground (by the throttle cable bracket on my rider).

You should never by pass any safety sensors on your lawn mower. BUT :for testing your brake sensor you can try taking the wires off the switch that is hooked ether at the back of the peddle or on the linkage and join them together .That should bypass it until you get a new switch.
There could be many reasons why your Sears riding lawn mower won' shut off. The key could be jammed for example.

Home Depot does have a repair service that repairs lawn mowers. You drop off the mower, they fix it and you pick it up at your convenience.
If the mower has a shift knob control for "Start" "Run" and 'Stop', the kill switch will be on the end of the cable that leads to the throttle bracket. If the mower has the safety handle that shuts off the mower when it is not depressed, the kill switch will be at the end of the cable that leads from the handle to the engine. If the mower is operated with an on-off ignition switch, the kill switch wire will be spliced to the switch "off" wire some where between the throttle cable and the switch.
