The is a safety switch located underneath the mower, in the dashboard area. This switch will not pass voltage to the ignition system unless the pedal is depressed, or the deck is not all the way up. However, your culprit is most likely the pto (power take off) switch on the dash that engages the blades. It will not allow the mower to start, if pulled, and if faulty will shut off ignition power when you release the pedal. First. You'll need a volunteer to sit on the mower and operate the controls. Now put the deck down and with the pedal depressed start the engine. Nothing should happen, if it does replace the deck switch Sears part number #176138 mentioned above. Now raise the deck and release the pedal. Again, nothing should happen. Same solution if it does. If nothing happens on both tests the switch is ok. NOW. Behind the dash, find the pto switch, and squeeze the sides, depressing two clips that hold it in the dash. You should now be able to slide it though the dash, wiring attached. Unplug the switch. With pedal depressed, deck up, someone sitting on the seat, start the mower. Now release the pedal (making sure to block the wheels and have the transmission handle is in the neutral position. If the engine continues to run, you found the problem. Replace the PTO switch. Sears part number # 174651. Also, check the plug to the pto, ignition and deck switches for corrosion as this is a common problem, though not likely to cause yours, it could. Good luck, and please let us know the outcome, good or bad. Thanks so much.

Under the seat, there is a operator presence switch, if this switch fails, the mower will shut off when the brake is released, or put in any gear.

There is an operator presence switch under the seat...it is more than likely faulty and must be replaced in order for the mower to run right.
