hydro lawn mower wont move.

Every once in a while my mower wont move. when i release the clutch/brake it stalls the engine. It does not matter if in reverse,neutral, or foward. Some times if i wiggle the belt and move it a little the mower will start to move a again. But this time my mower is suck in a half foot deep mud and water. The mower was moving then i shut it off to get some thing then when i came back to start it, it started but stalled when i put it in gear. This happened beffore ussually it is when the mower is parked on a hill. It is a 2005 Craftsman lt1000 with the Kholer 17hp OHV engine with hydrostatic trans-axel. Any ideas???

sounds like a stuck brake. wet belt will cause it to slip.. but not stall the motor. could be the hydro pump locking up too.

Thanks..but is was the saftey button under the seat.

Seat switch or bypass lever?

the button uder the seat so when you stand up the mower shuts off..that button...
the button came loose..that was the problem

It sounded like the motor was bogging down under load and dying. sorry for the bad info.
I have heard that a friend of a friend ( not me) pushed the button in and shoved a cotter key in it and bent it over to jam the switch.( again not me , and I cant condone such actions) not safe on a go fast trail mower. if you flip it over and fall off, you dont want it running very long..but usually they will suck oil in the cylinder and die anyway

i am not removing it under the seat beacuse i might be using a mowing deck

yea i ripped out all my wiring including the safety switches. then decided i wanted one encase i fell off so i rigged the under seat one back up.

yea i left every thing on because i dont know any thing about the wiring in lawn mowers and like i said i might be getting a mowing deck for it.
