Why won't my Jacobsen Lawn Mower engine start?

  If your Jacobsen Lawn Mower's engine won't start, first ensure the parking brake is engaged, the traction pedal is in Neutral, and the mow switch is OFF. Then, check the interlock system and follow the correct start-up procedure. Other potential 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 (fill with fresh fuel, change the fuel filter, and bleed the fuel lines), a blown fuse (replace it), a defective relay (test and replace it), or a misadjusted or defective neutral switch on the traction pedal (adjust or replace it).

How to fix uneven cuts from Jacobsen Lawn Mower reels?

  Andrea RodriguezAug 16, 2025
  If your Jacobsen Lawn Mower's reels cut unevenly, start by inspecting the bedknife-to-reel adjustment. Also check the engine speed. Ensure the mow speed is properly adjusted for the turf conditions and that the mow switch is set for Forward rotation. If issues persist, verify that there's enough rear roller pressure by moving the down pressure spring one hole towards the spring. If the front roller isn't following undulations well, move the down pressure spring one hole away from the spring.

  If your Jacobsen Lawn Mower engine stops, the fuel tank may be empty; refill it with fresh fuel and bleed the fuel lines. Another cause may be that the interlocks were not set before you left the operator’s seat; engage the parking brake and set the mow switch to “OFF”.

  If the battery on your Jacobsen Lawn Mower isn't holding a charge and the battery light is on, inspect and clean any loose or corroded battery terminals. If the electrolyte is low, refill it to the correct level. Check if the alternator belt is loose or broken, and tighten or replace it as needed.
