This tractor actually belongs to my brother. I just get to work on it. When he originally told me of the problem, I evidently misunderstood. I thought he said he stopped the tractor to clean it off, and then it wouldn't restart. Today, he said it stopped running by itself just as he was getting ready to shut it off. He then said it wouldn't restart. He said it acted like a dead battery. This may be a different problem entirely. Anyway, let me list everything that has been checked so far: 1) battery was tested (at Advance Auto) and showed about 12.5 volts and 540 cranking amps, 2) jumped battery post on starter to post on solenoid and nothing happened, 3) battery terminals and cable ends on battery were cleaned, 4) ground cable connection was cleaned, 5) battery cable/wire connections at starter were cleaned, 6) connected jumper cable from positive battery terminal to terminal on starter - WHEN THIS WAS DONE THE INDICATOR LIGHTS ON THE INSTRUMENT PANEL THEN LIT WHEN THE KEY SWITCH WAS TURNED TO "ON". We then tried to start the tractor, but it cranked VERY slowly. The engine would not crank fast enough to start. There is definitely a problem with the positive battery cable. Then used my truck to try to jump start the tractor. Connected positive jumper cable directly to the starter and grounded the negative cable to the tractor frame. This bypassed the tractor battery and battery cables. The indicator lights lit when the key was turned ON, but the engine would still not crank fast enough to start. I then removed the starter from the engine and connected the jumper cables to it. When the key was turned ON, the starter seemed to spin freely with the pinion gear extending as it should. The starter was reinstalled, the jumper cables were connected again (to starter and ground), but the engine STILL cranked very slowly. The battery will be tested again, we'll get a new positive cable, but the fact the tractor stopped running on it's own is NOT a good sign.
