as i have said before i am not a mechanic but will do what i can. i have narrowed my problem down to my starter. it is slow turing over and will start with a boost, the battery is good and alternator is putting out 14 v. the ground is ok.. the big post coming from the starter gets hot and i am sure i saw some smoke. i want to take the starter off and get it tested. i can only see one bolt on the side of the starter where it goes into the fly wheel. is this how it comes off. also i know i have to take off the battery cable first. does it matter which one and if so why if i need a new starter are they scarce or expensive. thanks

Anytime you mess with battery cables at either end, You should remove the negtive battery clamp first. You do this to prevent the cable acciedently touching a ground and sparking. I've had this happen on another brand of tractor and where the choke cable ran near the starter an the cable touched the choke cable and welded it so I couldn't work it in and out. I had to replace the choke cable to. and if there is a little gas around I think you can see what could happen. Have you cleaned the battery cable clamps, I've seen a truck that won't start the jump it and it started fine, so they switch batteries for another truck that was starting fine. still woundn't start hood up the jumper cables and it start. Then cleaned that clamps and post and it started fine, the extra pressure of the jumper cables would make good contact. It looks like to me that you loosen the one bolt and the start will come out. So first disconnect the negitive battery cable. Then remove the wiring on the starter and loosen the bolt and slide the starter out.

Cobra There is an hard plastic insulator around the post going into the starter; it sometimes cracks causing a short (you will see smoke and/or sparks around the post when it happens). Happened to me on a D14 (twice). Fortunately, the local generator repair person had a bin full and they were not expensive. Good advice re: disconnecting the battery and removing the starter.

While you're 'testing the starter', I'd replace the cables with new one piece molded 'big fat' ones( all of them !). Any cables that have had the ends 'bolted' or 'clamped' on will go bad from the inside out( copper corrodes),causing all sorts of grief.Be sure to lightly coat the studs with a dab of oil or grease to reduce corrosion as well.
Also be sure where the starter mates is good clean steel !

Sometimes the starters just get a bad ground. Try removing rust at places that contact housing and from the socket that the retainer bolt goes into. I little action from a wire wheel helps assure you are not loosing on that side.

The large bolt on the side is all that holds the starter in the hole. clean the inside of the hole and the outside of the starter for a good ground.
Remove the ground side of the battery first, because if you remove the hot side first and hit the steel any place in the process, you would have fireworks. If the tractor is still original, it will be positive ground. If it has been converted to an alternator, it will be negative ground. The smoke and heat could just be from a bad connection on the starter or from the starter pulling too many amps. Take it to a starter/genny shop and have it checked. Bob

While new starters can be hard to find, the originals can be rebuilt easily by any auto electric place.
