Mower dies when i try to engage blade

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

    there is no ! main switch that controls all that is what I am thinking your looking for. there are 2 or 3 different switches working together to create the safety circuit.in otherwards there is a pto safety/seat safety/brake safety. usually won't start unless but in seat. most of the time the brake or clutch leve safety gets corroded and kills it when you try and engage blades.

    Hi, I had the same problem. I had too replace the (electric clutch pulley) it,s on the main shaft and the belt goes from the clutch pulley too the mower deck pulley. too check to see if that's the problem, turn the key on (don,t start the engine) turn the mower blade buy hand and see if you can move it or not. if not the clutch could be burnt out.



    If this doesn’t work for you, please write back. Thanks,

Why does my riding mower die when put in gear or engage the blades


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.

check the "kill switch" they are usually located in the seating area. it senses for pressure or seat angle and will kill the mower if nobody is sitting on the mower. Good Luck

Husqvarna 17530 stalls when engaging the blade. Seems to run fine else wise/


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 Dis-engaged?
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.

Hope this helped Tim

Hi
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.
