I'm curious as well. Would love to know the answer. I'm NOT a mechanic, but does the starter work in conjunction with something else that may have been "accidentally fixed"?
Tractor stalled and now will not start - any ideas
- Thread starter Sparty047
- Start date
So the consensus seems to be the issue was not the starter. OR at least the speculation is.
BUT the starter did turn the engine over.
I too am confused. If the starter turned the engine then the issue was not the solenoid. BUT perhaps the starter was turning the engine more slowly than normal due to an internal failure?
After posting this I will have to go back and reread the OP’s conclusions.
Edit: sounds like the OP bought a replacement started and the issue resolved. If I were a betting man, I would bet the starter motor was failing and turning the engine slower than normal, but I think one would pick that up as slow cranking similar to having a weak battery.
I remain confused, but glad the OP is back in business!

Boy! My expertise with tractor mechanics is close to nil. Yes, the engine cranked but did not fire. Neither did I appreciate that the engine was cranking slower than ususal. Someone farrrr wiser than me can perhaps explain how the starter can be defective in such a manner that this can happen. I did nothing further with the fuel supply and electrical connections to the starter were not altered in making the change.
Good luck with your tractor.....there are senior members here whose advice you'd be wise to follow.
I’ve always been a big proponent of A-B-A troubleshooting whenever practical. Some of my customers used to give me the stink eye big time when I would take the time to then put the BAD part back in to make it fault out again, but for the cost of a $25K part, it made all the sense in the world (useful with solid failures only, obviously).
Wow!
I was aware that a starter engages and turns the engine. I did not know if the electric circuit within the starter served any other purpose.
I had completed all tasks for clearing out the fuel lines and verified good fuel flow to the pump. I had cranked the engine 15 or 20 times over two days without a hint of combustion. Cranking seemed as always with no noticeable slowing.
I did nothing else to the fuel lines or electrical circuit before replacing the starter. I only detached the leads on the old starter. After the new starter was in place, I turned the key and the engine started with 2 seconds.
I don't see how I could have "accidently" repaired the primary issue.
GO FIGURE??!!

My SPECULATION would be that the rate at which the air/fuel mixture in the cylinders is compressed affects combustion. Faster compression resulting from faster starter rotation might increase the heat generated within the cylinders and aid initial combustion.
I would bet on this…but not much. Hopefully somewhen with more knowledge can offer an opinion.
I too think the starter was likely the primary issue. OR something related to it, that was limiting current flow through the starter, resulting in less speed/torque being developed by the starter.
You could always satisfy your curiosity and put the old starter back in and see what happens.
These engines require a certain minimum cranking speed.
If you look at a diagram of the starter, you'll see an internal relay. I'm not sure exactly how it all works, but you have motor brushes that could wear/burn. The commutator connections can go bad or a coil can short or burn out. The contacts on that relay can also wear/burn. Any of those or a combination could reduce the starter current/power.
