Question about John Deere Garden

Open Question

My JD ltr 180 will not run with the seat safety switch engaged.

I have a ltr 180 riding lawn mower. It was cutting out so I replaced the switch located in the seat. Now it will only run when the switch is disengaged, in other words the only time it runs is when the switch button in not depressed. Exactly the opposite of the way it should work. I then replaced the brake switch and the pto switch. I still have a mower that won't run unless the seat switch is out and not depressed. Of course that would be fine if all I did was ride on it but when I engage the pto or blade it kills the motor.

SOURCE: Started up...then died as if safety switch 18HP craftsman rider

On later models there are possibly three safety switches, one under the seat, one for the blade engage mechanism or blade clutch so the blades don't turn when the mower is started, and a neutral safety switch to make sure the mower is in neutral before it starts.

SOURCE: shuts down in reverse

I'm not familiar with that particular mower but I'd bet it is a direct switch. Follow the shifter arm down and you should see a arm or button that arm contacts a switch when you put it in reverse. pull the two wires off that switch, put a wire in between to connect them and it is by-passed.

Please rate if this helps-

SOURCE: Husqvarna yth2448 pto switch kills motor/battery will not charge

you may hav a bad alt. problem with the mower dying when you engage the pto is most likley a bad sensor or wire unplugged on the seat sensor.the way it works is if the blades are turning and it dosent sense you being on the seat the mower shuts down.this has been standard on mowers for quite a few years now. it keeps the blades from cutting you up if you fall off the seat while mowing. as for charging i would try cleaning the battery connections and get the battery checked first.

SOURCE: husqvarna 2448 pto switch kills engine,bldes

try unplugging the pto, start the mower, then engage the pto switch. If the fuse still blows trouble is somewhere in the mowers wiring if not the ploblem lies in the pto. hope this helps

Craftsman riding lawn mower won t cut grass

Does it die when you attempt to engage the cutting deck? If so the you might have a clogged fuel filter, bad gas, dirty air filter, bad spark plug.
Or the mower engage switch may be faulty. They are located in different places on different mowers. But should be attached somewhere along the main pivot of the engage lever. Let me know if you need more assistance. Good Luck!!

Husqvarna Riding Lawn Mower 46 Cut model #454140010G MOWER will not ingadge

I can not say this enough, check the safety switches. There should be one on the seat, the clutch /brake pedal and /or the equipment pto switch. Also, check the wires running to these switches. They tend to move and vibrate as you mow and a worn spot in the wires can cause a short, resulting in the mower not starting.

Good Luck!!!
