LGT1054 - Will crank but not start

[als_84]

Hello there. I found you guys through many, MANY of the Google searches over the last week. I am hoping someone with more knowledge than me on small engines can help point me in the right direction.

Tractor is a LGT1054 and has a Kohler 7000 series engine.
75% full of fuel (so yes I have gas in the tank! LOL).
Oil level is correct.
PTO switch disengaged. Parking brake engaged.

All this year thus far, in order to start the tractor, I would have to hook it up to an amp charger / engine starter. It would barely crank, but eventually I could get it to start. Then I manually had to push it about 50 ft. into my garage to start the process of fixing it because no matter how hard I tried, I could not get the damn thing to start.

So, given the battery issue, my first replacement was the solenoid. Still having trouble getting it to crank over, even hooked up to the charger. So I replaced the battery with a brand new one. No change. Went through and replaced the oil and the oil filter as well as the fuel filter and air filter. Traced all the wires I could and cleaned connections. No luck.

The next thing I replaced were the spark plugs. Ensured they were gapped properly. No change. Then I replaced the starter. This is where we saw a MAJOR improvement in the cranking (so I needed the starter replaced regardless of it not fixing the issue). The engine cranks beautifully and is definitely getting power. I used choke and carb cleaner as well as engine starter. After numerous attempts to start it I do have to put it on the charger/starter because the battery seems depleted. So at this point the engine is cranking but not starting.

I even went so far as to clean the ignition module connected to the spark plugs and the flywheel surface with Emery cloth to ensure that both the flywheel and the ignition module were free of any rust or corrosion. Still only cranks, does not start.

I am at a loss as to what to do next. I'm pretty handy and understand electrical diagrams and the troubleshooting process. I would greatly appreciate any help you guys can give.

All parts replaced were replaced with OEM parts directly from my local Cub Cadet dealer. All parts replaced:

Solenoid
Oil
Oil Filter
Fuel Filter
Spark Plugs (2)
Starter

Please send help. Grass continues to grow and there is just way too much to cut by hand with a mower.

First, welcome to OCC...........

Couple of questions...

(A) How old is this tractor ??

(B) When was the last time it operated correctly ??

(C) When the engine rolls over, does it roll over normal, or slower then normal ??

2 years ago? Thats when we had no issue starting it short of maybe a drained battery.

The engine cranks beautifully. It does not "turn over" atm though.

Just so we understand this correctly, when you turn the key, the engine does NOT roll over ??

When the ignition key is turned, there is power to the engine but no combustion. The fan above the flywheel spins smoothly and you can tell that the engine is getting power. This improved drastically when I replaced the starter. I get no further then the fan spinning and a "crank" from the engine. I hope that makes sense.

Did you check for spark across the plugs?
