Why won't my Jacobsen Lawn Mower engine start?

  Your Jacobsen Lawn Mower engine might not start due to several reasons. It could be due to the parking brake being disengaged, the traction pedal not in Neutral, or the mow switch being ON. Check the interlock system and start-up procedure. Another reason might be a low or defective battery, so inspect the battery's condition and connections. The fuel tank could also be empty or contain dirty fuel; in this case, fill it with fresh fuel, change the fuel filter, and bleed the fuel lines. A blown fuse or a defective relay could also be the culprit, so replace the fuse or test and replace the relay, respectively. Finally, the neutral switch on the traction pedal might be out of adjustment or defective, requiring adjustment or replacement.

  If your Jacobsen Lawn Mower battery is not holding a charge and the battery light is on, it could be due to loose or corroded battery terminals. Inspect and clean the terminals. Another reason could be low electrolyte levels, so refill to the correct level. A loose or broken alternator belt could also be the cause, so tighten or replace the belt. For issues related to the charging system, consult the engine manual.

How to fix uneven cuts with a Jacobsen LF 4675 TURBO?

  Stephanie MullinsSep 3, 2025
  If your Jacobsen Lawn Mower reels cut unevenly, the bedknife-to-reel might not be adjusted correctly, so inspect the bedknife-to-reel adjustment. The engine speed could be too low, so check the engine speed. Also, the mow speed might not be adjusted for the turf conditions, so adjust the mow speed for the best cut. Ensure the mow switch is set for Forward rotation and not Reverse. Insufficient rear roller pressure can cause uneven cuts, so move the down pressure spring one hole towards the spring. If the front roller isn't following undulations adequately, move the down pressure spring one hole away from the spring.
