How Often Should You Change Your Drive Belt?

As you operate your riding mower, you put stress on its engine parts and other components. Troy-Bilt Horse Riding Mowers can handle much of this stress. However, they will start to wear down after a while.

  • New drive belt

How to Change the Drive Belt on a Troy-Bilt Horse Riding Mower

Once you’ve gathered the needed tools, you’re ready to get started with the project. Start by parking your mower on level ground with the parking brake engaged.

Then, unplug the spark plug wire and disengage the power take-off lever to keep yourself safe. After that, you’re ready to begin.

  • Move the mower deck lift lever to its lowest setting. Once you have, push the lever to the right to lock that position in place. You’ll find this near your riding mower’s right rear fender.
  • Use a socket wrench to unscrew the mower deck belt guard retaining bolts. These are located on the top of both the left and right side of the mower deck, between the mower deck assembly and the riding mower frame.
  • Use a socket wrench to unscrew the engine pulley belt keeper. After, slide the belt keeper rod from the lawnmower frame. This will allow the mower deck belt to be removed from the engine pulley. You’ll find the engine pulley belt keeper rod beneath the engine.
  • Find the mower deck idler pulley on the top left side of the mower deck. Once you have, insert the 3/8-inch ratchet square into the pulley bracket square hole. Then, move the ratchet to the “loosen” position. Finish this step by pulling the ratchet handle backward to relieve the mower deck drive belt tension.
  • Slip the mower deck drive belt from the left side spindle pulley and remove it from the idler pulley bracket. You’ll need to hold the ratchet with one hand while doing this.
  • Route the new drive belt around the engine pulley. The belt should fit perfectly. Once you’ve got it set, reinsert the engine pulley belt keeper rod into the mower’s frame. Tighten it with your socket wrench to keep it secure.
  • Pull the mower deck drive belt toward the rear of the riding mower. Then, you need to guide the flat side of the drive belt around the right side idler pulley. You’ll finish this step by routing the V-shaped side of the belt into the right side of the spindle pulley groove.
  • Pull the V-shaped side of the drive belt around the left side spindle pulley. Next, insert the ratchet into the left side pulley bracket and pull it backward. This will relieve the idler pulley tension. Once you’ve done that, slip the flat side of the drive belt around the left side idler pulley.
  • Reattach the left and right side drive belt guards with your socket wrench. Remember, these go just over the left and right spindle pulleys.
  • Start the riding mower, let it idle for a few minutes, then test drive it around your yard. Try engaging and disengaging the blades while you do. You should learn pretty quickly whether your drive belt replacement process was a successful one or not.
