How to change the drive belt on the Troy Bilt Bronco riding mower?
Worn belts are one of the most important signs that the drive belt requires replacement. To ensure high working efficiency, after only one to two cutting seasons, we need to replace. We can approach and replace it in many ways but in our opinion, the method given below will be the most effective.
Step 1: Adjusting the machine lever
We will pull the floor lift lever all the way forward to adjust the floor to the lowest level. Move the lever to the right and lock the latch in that position. The lawn mower floor needs to be raised on the rightmost rear mud plate.
Step 2: Adjusting the deck guard
The bolts securing the deck securing belt shall be cut from the top of the deck. The lawn mower deck belt guard will then be lifted from the top of the mower deck and set aside. We will reposition the deck guard on the top of the right and left mower deck pulleys, between the deck assembly and the lawn mower frame.
Step 3: Detach the deck straps placed on the pulley
We will remove the belt placed on the pulley with a socket wrench. Then slide the belt retainer off the chassis to allow the deck belt to leave the pulley. The pulley belt holder will be located just below the engine.

Double-check the position of the pulley on the engine deck on the left side. We will then proceed to insert a 3/8 inch ratchet square end into the hole of the roc net holder. Note that the ratchet must be set to a “loose” position.
Next, we will pull the ratchet handle back to move the pulley. This will help reduce the strain on the drive belt on the breaker deck.
Step 5: Slide the cutter deck drive belt from the main shaft pulley.

Step 6: Thread the drive belt around the engine pulley
The groove of the pulley perfectly accepts the V-shaped face of the drive belt. Install the motor pulley belt retainer to the lawn mower frame. Next, it is necessary to tighten the bolt that holds the belt bar of the engine pulley with a socket wrench. This prevents the belt from slipping off the pulley.
Step 7: Move the drive belt
The drive belt will be pulled to the back of the lawn mower. Direct the plane of the drive belt on the cutter deck around the pulley. Route the V-shaped face to the main shaft groove of the right pulley.
Step 8: Left spindle pulley handling
