I can't find this switch in the schematic on sears site. while not engaged this switch is made (pushed in) when released the tractor dies. The seat switch kills it also when released, so does the clutch/brake switch

iFixitI have an older Murray riding lawn mower, whenever I engage the mower the engine dies, otherwise it runs .... My dr feild brush mower ... cuts off when I engage theblades. ... My Huskee only shut off once I put it in drive with the blade engage.
Check out the grass box safety switch. if not fully depressed it will apply brakes to the blades when in gear. Most mowers are designed with a safety switch to stop the blades, or forward motion if the grass box is not fitted correctly.
Does engaging the pedal for the PTO lug the engine down, or does it just die like turning off the key?
If it lugs the engine down, then you need to make sure you can spin the
spindle and idler pulleys by pulling the belt by hand. You should be
able to slip it around the engine pulley enough with the blade pedal
disengaged. Pull the belt up tight so the slack is around the engine
pulley and try to spin the blade spindle and idler pulleys.
If it dies like turning off the key, then its likely a safety switch and may require a meter to test which.
The seat switch is has a shunt in the circuit that must be satisfied in
order for the rest of the circuit to be happy. Make sure the connections
are good, the pins inside the amp connectors will sometimes spread,
push out of the lock etc. and if connection is lost will not work.
Otherwise a new seat switch will be needed. You might check the PTO
switch for continuity, without a diagram or schematic I am not sure how
your circuit is wired. you have to have the parking brake
engaged to get off the mower while the engine is running and the PTO is
I don't know if your "go" pedal eliminated this switch or not. But if
with the parking brake engaged and the PTO disengaged, you lift off
the seat and it dies, then its the seat switch.
Check for burnt fuse behind dash. If no burnt fuses check if getting power to magnetic clutch mounted on bottom of engine crankshaft. Make sure wires are not broken by magnetic clutch. Make sure the safety seat switch is working. Make sure you are sitting on the seat when you try to engage the blades. If that does not work try pushing and wiggling the seat sensor. Check make sure wire is attached to safety switch under seat.
