Why won't the start motor turn on my LS tractor when I turn the key?
- R
  Ryan LarsonAug 20, 2025
  The start motor may fail to turn when you turn the key in your LS tractor due to several reasons: the start safety switch may not be contacted, so depress the clutch pedal fully; the PTO switch may not be in the “OFF” position, so place the PTO switch in the “OFF” position; the battery may be discharged, so charge or replace it; the terminal may be loosened, so tighten it; the key switch may have failed, so repair or replace it; or the start motor itself may have failed, so repair or replace it.

  Mike JuarezAug 22, 2025
  If your LS tractor engine overheats, it could be due to a lack of engine coolant, in which case you should supplement it. It may also be caused by bad fan belt tension or a broken belt, so adjust the belt tension or replace the belt. Another possible cause is dirt attached to the radiator; in this case, clean the radiator.

  If the start motor turns but the engine doesn't start in your LS tractor, the battery may be weak, so charge or replace it. There may be a bad ground, so tighten the ground. The engine oil may have improper viscosity, so replace the oil with proper viscosity. There could be air in the fuel system, so bleed the air. The fuel filter might be clogged, so wash or replace the filter. There may be an error in the engine body, so repair it. Finally, the fuel cock may be closed, so open the cock.
