Craftsman LT1000 ridign mower engine dies after 15 min-deadman on

My riding lawnmower engine dies after 15-20 minutes. The deadman switch under the seat is connected as good as it can be. It seems like something is getting too hot and it kills the engine. Could it be the wiring of the deadman switch needs replacing??
I have changed: fuel filter, partial fuel hose, oil & oil filter, air filter, belts, throttle lever (maybe not set back correctly?) and put water remover in the gas.. What now??

There are several things that could be going on, but what you said in your description about the dead man switch in the seat may need your attention first. The switch it self could also be bad. After you rule this out the next thing I would check is the fuel shut off solenoid located on the carb when you turn the key on to run you should hear a click and feel it in the solenoid. After this you may have a fuel pump issue or a coil issue. but from what you I have described I believethe first 2 itmes I mentioned should fix your problem

Your problem is very simple....loosen your gas cap and let some air in the tank then tighten back up and it will run like a charm....about every 30 min. of use just loosen cap a little and repeat....sounds crazy but an old timer mechanic told me about this and it worked...no more problems.....good luck

Engine shuts down when cutting deck engaged


This is probably due to a misadjusted or faulty safety switch on the rider's seat. There is a deadman switch there that will shut down the mower if the rider gets off the seat with the blades engaged.

My poulan riding lawnmower dies when I release brake pedle why


Sounds like there is a short in the seat safety switch making the unit think your not on the seat. Check the connections under the seat when you flip it up there should be wires and a pressure switch.

On john deere la150, if i sit on seat and engage blades,,,nothing, but when i lift of seat, blades engage and motor shuts off. Replaced seat switch and did not fix problem


"On john deere la150, if i sit on seat and engage blades,,,nothing, but when i lift of seat, blades engage and motor shuts off. Replaced seat switch and did not fix problem" Okay, what I'm hearing is that "nothing" means the blades-driving PTO won't engage (declutch) when you switch on mower; but then, (say) as you start to dismount the mower (seat) the mower (drive clutch) engages even as the deadman switch (seat switch) kills the engine (and the drive/pto shaft starts to slow down. The key here seems to be that at full engine torque the clutch is unable to remain engaged but, rather, slips so that mower blade inertia (resistence) cannot be overcome...but as engine/pto rotation slows the clutch is able not to slip. First place to consider is the clutch gap which is probably to0 large (possibly from wear and tear, possibly not). So check specs and how-to from manual or factory and reset the pto drive clutch gap...not hard to do. If clutch gap is not the problem then most likely rehab or replacement of the clutch assy will be needed...is the mower has many years use sufficient to wear out the clutch. Another possiblity is an electic (wring/switching/grounding) problem involving mower and deadman switches.

I have a sears craftsman riding lawnmower LT2000 model #917.273751 18hp intek engine 42in deck.Engine runs fine but when I release the clutch-brake pedal engine stalls.seems like an intermitent problem...


There are other safety switches as well. The electrical diagram shows (2) of the interlock switches (part no. 16 in diagram) in the electrical system. The location of the 2nd one could be on the transmission or the clutch/brake pedal. It could also be on the PTO system (blade actuator if you will). See if you can find the other switch on your unit. I have an LT1000 and have NOT looked for them. Here is an electrical diagram on your unit.

Serviced my riding lawnmower runs great. but when I put in drive it dies out. Also when I engage blades it dies out. No problems last summer. It won,t stay running when I do these two steps


Probably the seat safety switch. If it's not activated (from your weight on the seat) the engine is killed when you put it in gear, or engage the blades. Lift up the seat and check the switch - wires on tight? switch tightly mounted? You can take the switch out and tape it in the pushed-in position to test things. If that doesn't let the mower run, the switch itself is probably bad, but it could also be a connector that knocked loose when you serviced the mower. Check wires and connectors. Good luck!
