Idk what model you have, but it could be a sensor of some sort. On my zero turn, if the seat pressure sensor or steering arm sensors get dirty or go out, the mower won't start. In those instances, I could start it by jumping the starter. Just something to consider...

You can. Glass the safety switch easily with a zip tie


more detail needed please

Underneath your seat is a safety shut off safety switch. You can pull it out from the seat. Mine is a box with a button that is engaged when you sit. Zip tie it down. It did mine a year ago. It slips off some times and I just slip the tie back on the button

Sounds like starter solenoid is out. Can u use a screwdriver to jump the solenoid and then it turns over?


I can jump it, but then it cuts out after a few seconds

My 10 year old Troy bilt has a 20 Amp fuse, just like the ones in cars, loosely connected. Often times, if there has been rain, etc. this fuse will blow. After that, nothing occurs. Check to see if you have this fuse as well.

Safety switch either under the seat or at the clutch. Those go bad if you look at them wrong.

The reason why I say this!.
If you immediately lose power the switch Iis deactivating shutting down power to the ignition

If you was fuel pump you would have slowly seen a decrease in performance over time until the pump just finally died. Similar with carb it would have started giving minor issue and grow larger into total shutdown.
Soleniod you would never be able to start it even for a short period.

Again, it is hard to diagnose without looking at the unit.

I have a husquvarna and recently I was having intermittent problems that sound like yours. It wouldn't turn over at all. But occasionally it would turn over but die suddenly.

The problem was the fuse had completely melted away and the fuse holder had melted away about 50%. I could wiggle it a little and the wires in the fuse would touch enough to start.

1. Check the fuse.
2. Check the battery
3. Try jumping across the starter solenoid. Use some good pliers and touch both sides.


If it's the fuse, obviously that's easy to change. If it need a new fuse holder, it's not too hard to change and you can get one at Walmart or possibly lowes.

Does it have fuel?


Ain't shite happening if you don't have fuel in it.

It would turn over if it's a fuel problem

couple weeks ago my mower wouldn't start.

charged battery was reading correct voltage and full charge.

so then i replaced spark plug and starter solenoid.
cleaned carb and changed oil and cleaned filter.

no start.

then checked how many volts there were when i tried to start.
showed only 4 volts when i turned the key.

bought a new 19hp battery and running fine again.

check your voltage when you turn key,might save dollars and wasted time.

Yep.
Take the battery to get tested. Under load is not the same as sitting there. The amps are important when teying to spin that motor over

The concerning part is that it starts, then dies after a few seconds. Try removing your air filter and getting it started. When it starts to die spray a little starter fluid down the carburetor throat.

If it starts to run again, you have a fuel problem. If it doesn't help it you have an electrical problem. If the starting fluid will keep it running I am betting your mower has a little cheesy fuel filter inline. It costs a few dollars and is easy to change.

If this ends up being the problem, after you change it put a little Seafoam in the gas and it will clean out any muck in your fuel system.

ETA: I have an 8 year old Husqvarna LGT-2654. Just letting all you Husqvarna boys know I'm with you.
