Those coils are normally good or bad, but my dads would get hot and start acting up.

In my limited experience, it is common for coils to fail when hot. Transistors stop switching when hot but will work fine after they cool down.

Is this a new problem ? Thought it was just that it wouldn't start but once started ran well ?

Yes I think its the same problem, the engine will not run longer than 5 to 10 mins.

Hello,

 
The engine would crank over just wouldn't start. The next day I went out and it started right up so I'm going to replace the ignition module. It's going to be a couple weeks but I'll let everyone know if that fixes the problem.
 
Thanks again for everyone's help.

Are you buying OEM or aftermarket module? I assume you have to pull the engine as I do on my Gravely 18-H?

Hello Artbus, yes the engine has to come out and I'm going back with OEM. I only want to do this once LOL.

Good luck. My rig is 24 years old and I have considered changing it coil a few times as PM but have not yet. Have pulled the engine (Kohler M18) a couple times to replace oil seal. You may already know this but the magnetic force is strong so set your gap a little heavy and the magnetic field will pull her into spec. I agree, stay with OEM.

From what I've read in the engine manual, do not apply any power to the kill wire(will cause module damage), only needs to be grounded to stop engine. The relay gets energized when the switch is turned on which would open the Normally Closed contacts allowing the engine run. the print shows the kill wire going thru a relay(assuming it's the only relay, same as the seat switch stuff). I'm fighting the same print, putting a real wiring harness on my GT, the original had been cannibalized down to 3 wires. Good luck!!

The engine has been pulled, new ignition module installed. I should have time this week to install the engine back into the tractor and do a test run.

Ok guys easy on my carpenter skills or lack of at building the A frame to pull the engine. LOL The engine was pulled, ignition replaced, everything back together and the tractor is running like new. Thanks again for all the help.

I am a little old guy @ 67, 5' 7" and 145 lbs. Have pulled this engine a few times over the 25 years I have owned her, most recently a few years ago. Have often thought about building a frame like you did but always ended up manhandling her. If you remove the oil filter, she will slide forward so you can get a better lifting angle. Then grimace and throw her up on your work bench. Having said all of that, if there is a next time, I will build a frame! Bet 2x4's would have been plenty strong enough.

Beautiful tractor!
