  If the starter motor of your Bolens Tractor doesn't energize but the solenoid clicks, it could be due to several reasons. First, the battery might be discharged, so try charging it. Second, there may be corroded or loose electrical connections on the solenoid or starter, so check those components. Finally, the solenoid itself might be inoperative, in which case you should check it and replace it if necessary.

  If the starter motor on your Bolens Tractor isn't energizing and the solenoid isn't clicking, here's what you can check: * Ensure the attachment drive is disengaged by disengaging the PTO. * Make sure the brake pedal is fully depressed. * Inspect and clean any corroded or loose electrical connections, especially the Red/White wire at the solenoid, and tighten them. * Check the attachment drive, brake, and key switches; replace them if they aren't working.

  If your Bolens Tractor battery discharges rapidly, check the water level and refill if it's low. If the water level is fine, the battery itself may be inoperative, and you should check it and replace it if necessary.

  If the attachment drive on your Bolens Tractor (QT-1666 & 1966 series only) is inoperative but the attachment drive light works, check the purple wire between the PTO switch and the electric clutch. It may be broken or loose. Also, the electric clutch itself may be inoperative, and you might need to replace it.

  Thomas YoungSep 3, 2025
  If your Bolens Tractor battery will not charge, start by checking for corroded or loose battery cables; clean and tighten them. If that doesn't solve the problem, the battery itself may be inoperative, so replace it. Additionally, the diode or rectifier/regulator could be inoperative; check the diode and replace it if necessary, and check the rectifier/regulator by substitutions.

Why does the engine kill when the attachment drive switch is turned on in my Bolens Tractor?
- M
  Michael PerezSep 9, 2025
  If the engine of your Bolens Tractor kills when the attachment drive switch is turned on, it could be because there is no operator in the seat. The seat switch must be activated either by an operator in the seat or the interlock switch button pulled up. Alternatively, the seat switch might not be adjusted properly, so adjust it so the switch is engaged when the operator is seated.

  If the attachments continue to operate on your Bolens Tractor (1666-05001 01 and later)(1966) when the operator is not seated, it could be due to several reasons: * The seat switch is not adjusted correctly; adjust it so the switch is disengaged when the operator is not seated. * The seat switch is inoperative; check and replace if necessary. * There are broken seat switch wires; connect or repair the blue wires between the seat switch and the attachment drive switch. * The attachment drive switch is inoperative; check and replace if necessary. * The condenser is inoperative; check and replace if necessary.
