Why Jacobsen AR-5 Lawn Mower engine will not start?
- A
  Andrew GreenAug 18, 2025
  If your Jacobsen Lawn Mower engine won't start, several factors could be at play. First, ensure the parking brake is engaged, the traction pedal is in Neutral, and the mow switch is OFF, addressing potential interlock system issues. Other possible causes include a glow plug that hasn't timed out (reset the ignition switch), a low or defective battery (inspect its condition and connections), an empty or dirty fuel tank (refill with fresh fuel, change the fuel filter, and bleed fuel lines), a blown fuse (replace it), a defective relay (test and replace), or a misadjusted or defective neutral switch on the traction pedal (adjust or replace the switch).

  If your Jacobsen Lawn Mower battery isn't holding a charge and the battery light is on, start by inspecting and cleaning any loose or corroded battery terminals. Also, check the electrolyte level and refill if it's low. A loose or broken alternator belt could also be the culprit; tighten or replace it as needed. If these steps don't resolve the issue, the charging system may be defective.
