  • 9N wonít crank
  • Tractor stalled and died while bush hogging. Tractor would not crank after that. Was able to jump the starter and it cranked just fine. Battery is good 6 volt. The start switch tested good for continuity. I am stumped.

  • Got the old girl started today. This is what I did. I changed the start switch and had no change in the ability to crank the tractor. At this point I am thinking a bad starter;so I took starter off and took it to a shop to have checked out. The shop said it looked new inside so didnít do anything to it. I found the resistor board had fallen apart so changes that even though I knew it wouldnít change the cranking ability. Finally I remove the battery and cleaned up the ground point on the tractor. Reinstalled battery and bam she cranked and started. Music to my ears.

  • Iwould suggest you check ALL grounds. Remove batt cables and scrape, wire brush all connections. It sounds as if you are not getting a clean ground. Also, you will want to remove the starter and scrape wire brush the bock and the starter where they bolt together. This is a Most common place where corrosion forms and kills the clean ground.

  • Fuel, Spark. Combustion. Usually one or both of the first two. You were able to start/run off of your jumper vehicle. New battery means nothing -get tested. 6V means nothing if not wired correctly. Due the fuel flow test first.

  • Don't ignor the battery cables. They will corrode off inside the insulation and look fine from the outside.

  • Are you telling us that the engine only turns over ( cranks) when you use a jumper battery?

    Or are you using the term " crank" when you mean START?

  • Tractor starter would turn the tractor over with jumper cables from my gator directly to starter and foot peg for ground.

  • How did you determine the battery was " good"? Did you check the voltage and/or specific gravity?

  • It's a very simple circuit. Make sure your battery connections are good and clean. Test your battery. Measuring it statically without a load on it won't work. If you have to take it to your parts store for testing, do so. If the battery TESTS good, using your volt meter, connect the meter's negative to the battery's positive clamp and use the meter negative and probe the start switch as you press the start button. IF that checks, go to the starter connection. My guess is either bad electrical connections or the mechanism between the start button actuator and the starter switch has a problem where it is not closing the start switch. I had that problem before. It was a worn starter switch. It tested good electrically but mechanically, its button was sitting too low and the start button's mechanism couldn't push it in far enough to close the starter switch.

  • Re: 9N wonít crank
  • Tractor stalled. Ran out of electricity? Generator / regulator not charging?
    Not crank after that. Corroded battery terminals / dirty ground?
    Jump the starter and it cranked fine.
    Cranked fine and no start tells me the genny is not putting out.
    Battery voltage is what?

    Others with vast more knowledge will be here shortly.

  • Re: 9N wonít crank
  • IIRC. Dell (RIP) said that the ignition switch could overheat/fail and the result was that the tractor would run for a while then quit. Someone may disagree, and I canít find the post.
