L3902 Won't start

[matt27919]

A chain of events happened: First I hit a branch with the oil filter and it bent the oil filter, leaking all the oil out. the tractor made a grinding noise for less than a second before shutting off. I replaced the oil and filter and now it still gives me a low pressure light on and will not start. I added the correct amount of oil, checked the dipstick. both plugs were tightened and so was the oil filter. When I turn the key to start, it makes one click and the lights on the dash go off. They light back up as soon as the key turns back to on. Not sure if its a starter, the low oil switch (part 11521-39013) or something else. If anyone knows what it could be I would appreciate the info! Tractor was bought in June 2020 and I really hope it isn't a seized engine. It was running like a champ before hand.

The low oil pressure light won't go off until the engine starts.

The behavior of the instrument panel lights sounds like a low battery or bad connection.

Time for some starting system checks.

Thank you

Did you shut it off or did it stall with no oil in it?

It shut off on its own and won't start back up.

Were you mowing when this happen? Did you leave the PTO switch on??

i was running the brush cutter and the PTO is shut off when i tried to restart it. might tinker with the linkage but its the push button pto switch so not hard to make sure its in the off position.

We could speculate all day and resolve nothing. If it won't crank jump battery to starter. If it cranks the engine is not seized.

Put a breaker bar on the crankshaft bolt and try to turn the engine over by hand(make sure the key is in the off position). Your instrument cluster behavior is normal when the key is in the start to on position, as this prevent voltage spikes from damaging components. If you can't get to the bolt on the crankshaft try the alternator bolt(go the tightening direction) or if you have a drain hole or inspection plug on the flywheel side put a prybar(big screw driver) and try to turn the engine over. Do you have insurance on the tractor?

How much oil did you have to add? How much was still in the engine?

Yes I have insurance. Haven't tried to turn the crank yet because it went out in the woods and its getting dark early now. Thank you.

the tractor made a grinding noise for less than a second before shutting off.

That pretty much tells the story, your engine is seized from lack of lubrication.
Get it recovered from the woods and to the dealership, file a claim with the insurance and the dealer can install the new engine.

Engine is junk.

Likely stacked bearing(s) or just plain seized (or partially seized, IOW, TIGHT!)

As whitetiger said, get it out of the woods and make it accessible to the recovery truck so they can haul it to a dealer.

Where is this tractor now?
