Deere Tractor Engine Trouble

16 years ago

Have a John Deere given to me years ago. It ran without a problem till last summer. All of a sudden the engine started stalling out when moving. If I am quick enough and adjust the throttle I can keep it going enough to get back to the barn. It will idle all day, but stall out as soon as I start moving. No load, no blade engagement just driving around the yard.

JD had had many different engines on them, I guessing a kohler? Guessing again on the stalling problem, First thing I would do would be clean and regap the spark plug, then some fuel system maintenance, especially if you hadn't done it for a couple of years.

I go the hole hog and do the entire system. This way I know I got good fuel to the carb. I start by removing the fuel tank and hose to the carb/fuel pump it it has one? I clean out the tank flush it several times and scrub it with a bottle brush. Now that I got a CLEAN gas tank I install new hose to the filter, new filter, new hose to the carb./fuel pump and from the pump to the carb.

Now I remove the carb. bowl (if it has one that can be removed) clean out the bowl and spray down the float area of the carb. Now put fresh gas in it add a fuel additive like sea foam or gummout/berrymans ect. and try that. If it still stalls you will have to clean the carb. and of course make sure the spark plug was cleaned and gapped.

Other possible problem areas, Weak coil, corroded coil or fly wheel, Bad spark plug wire from the coil, bad ground, dirty air filter ( I hope you've been cleaning and replacing it?), Carb. out of adjustment Leaned out. I sure there are more, but it my bed time, 3:50 comes mighty early at my age....

Well, if you took it to the Deere dealer last summer , they might almost have it done by now.... What model do you have? It is likely that you have a carburetor problem. Are you up to giving the carb a cleaning and change out the fuel/ fuel filter? Maybe even a funky wire shorts out kills the engine as the tractor starts to move. Less likely, but possible.

Dump contents of fuel tank into a clean plastic bucket. This will require removal of fuel tank. Allow to settle. check for dirt in fuel. The fuel cap will have some sort of breather hole. Check it with a needle or stiff skinny wire, poke in it, and blow thru the breather hole. Check fuel line for inner deterioration. Replace fuel filter if it has one. Will it run with fuel cap completely off?
Do you move throttle up for more speed after you start it. Might have to do that to make it move!
Maybe it needs a new air filter cartrige, or a new spark plug. Does it have a fuel pump? HTH Rusty J.
