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.

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

My ride on lawn mower is cutting out every time i try to engage the cutting blades

Sometimes it is due to the ETHANOL fuel you are using. ETHANOL is attracting moisture and after a while it builds up water in the tank.

I have a Bolens Model 13AM762F765 38inch cut 15.5 HP twin blade lawn tractor. It runs like a champ as long as I do not engage the blades or put it in reverse. It will stall if either of these two things...

Sounds like a safety switch. Just as there is a safety switch under the seat that shuts mower off if you get off seat while engine is running, theres also safety switches for, pto, drive, reverse, etc. I would get a multimeter and look for switches under chassis and test with meter for continuity.

I’m happy to assist further over the phone at

What causes JD 260 riding mower to start dying when you engage the mower deck? It runs fine when you disengage the mower deck.

It's the safety system that causes this. There is a switch under the seat that should activate when you are sitting in the seat. The switch can come loose or fail, the mounting can break, or the wires can come loose - any of these would cause the "engine dies when I engage the mower deck" behavior. Lift the seat, examine the switch. Rmove the switch and keep the plunger in with a piece of tape. Fixed? Then it's just the mounting or adjustment. Not fixed? It's the switch itself or the wires or connectors to it.

My husqvana lawn tractor starts well and the engine runs but when I release the brake or apply the cutter it cuts out. Why?

Most likely the seat safety switch or associated wiring is the problem. It's designed to cut the engine if you release the brake or engage the blades unless it detects your weight in the seat. Tip up the seat and make sure the safety switch under it has not come loose, and that the wire connections are on tight. If that all looks OK, take the switch off and put a piece of tape over it the plunger to keep it in the 'activated' position and see if the mower works that way. If that fixed it, you should replace the safety switch. They are just a few dollars. Hope this helps - if so, please rate my answer.

Mower won't run

Did you try jumping the switch under the seat? Why would the foot switch shut it down? If it is the switch near the foot and you can't replace, then jump it. But be careful this will disable saftey features. Hope this helps.
