How To Replace Drive Belt On Mtd Yard Machine Riding Mower

Step #1: Preparation For Changing Drive Belt

At first, take the lawnmower into a flat surface or your garage for the convenience of the work.

You will find the idler pulleys near the middle of the deck and the idler pulleys are smaller in size than the regular pulleys used in the mower. 

If you have a 42-inch mower deck, this step is only for you. If you have different sizes of the deck then skip the 6th step.

Notice how the belt is fastened around the pulley. Now remove the belt from the pulley by rolling it off. Carefully remove the belt from the pulley. 

Step #8: Install New Drive Belt

Now, install the new drive belt by following the same process as you remove the old drive belt. Make sure the V portion of the drive belt is attached to the pulley and stay at the parallel position with the grooves of the pulley. 

Step #9: Tighten The Idler Pulley Nuts

Use the ratchet to tighten the small nuts attached to the idler pulley center. Replace the belt keeper rod in its previous position. Attach it with the engine pulley. Replace the drive belt guard and use the screwdriver to attach the screws. 

Step #10: Test The Drive Belt

Now, turn the power of the mower on. Test the drive belt by engaging the mower blades. If the belt is installed correctly, the blades will move efficiently. If you face any difficulty, stop the lawnmower and check the belt again.
