Surprisingly, racing lawn mowers is becoming a popular past time. Some of these new lawn mower races are a result of people converting their regular lawn mowers into racing vehicles. The cost to convert these lawn mowers is relatively inexpensive compared to the costs of converting a regular car into a racing car. If you think you would like the experience of lawn mower racing, or you just want to try building your own racing lawn mower, here is how. Continue reading on.


Difficulty: Moderately Challenging


Things You’ll Need:

  • Wrenches
  • A lawn mower
  • Smaller pulleys
  • Possibly a new muffler
  • Possibly new and bigger tires

Begin by Changing Pulleys

Step 1

Change pulleys on the mower. Replace the original pulleys with smaller ones. This will allow your lawn mower to go faster. Remove the motor from the lawn mower. Carefully, invert the lawn mower. While you have it upside down, unfasten the dry belt from the pulley. You’ll need to use a wrench to unscrew the bolt and tap that secures the pulley into place. Replace with smaller pulley. Inspect the dry belt. Look for any signs of dry rotting, wear and tears. If any of these are present, replace the belt. Place the new dry belt back on the pulley. Bolt tightly.

Step 2

Inspect the lawn mower’s muffler. Look for any holes and corrosion on the surface of the muffler. Replace the muffler if there is any size hole found in it. Make sure there are not any tiny holes in the muffler either. These tiny holes can cause your vehicle to lose speed. Clean off any corrosion.

Step 3

Look on the carburetor and unhook the governors. Some lawn mowers will have more than one governor. The models that have more than one governor leads to the gas and the other to the throttle feed. Detach the lead from the throttle feed. This can increase power.

Step 4

Inspect tires for proper air pressure.

Step 5

Check guidelines of racing track you intend on trying. Some tracks require that you leave the mowing deck on your lawn mower. Others may say leave it. This is because the mowing deck stabilizes the lawn mower unit. This policy varies from race track to race track.

Step 6

Make your racing lawn mower your own. Paint and decorate your new racing mower in any style or design you want. You can even add some details like a racing number.

Step 7
