Pulley assembly

Hello Sherman , Great question. Have you checked your transmission ? Transmissions The transmission in a self-propelled lawnmower is an important part of the drive system. It connects to the engine by way of the drive belt, it changes the direction of drive rotation from vertical to horizontal, and it has gears that set the maximum drive speed and torque. Modern lawn mower transmissions are relatively trouble-free and are often maintenance-free as well. As with any moving part, with enough use it will wear out and need to be repaired or replaced. Extreme conditions, such as steep hills or a very dusty environment, will cause the transmission to wear out faster. Common symptoms of a worn or failed transmission are: grinding gears, starting and stopping or jerky operation, and the transmission pulley rotating while the wheels do not. Some transmissions have parts available and can be rebuilt, others must be replaced when they fail. Rebuilding a mower transmission is a more complicated repair so repair time, degree of difficulty, and overall cost should be weighed when deciding whether to rebuild or simply replace a faulty transmission. Replacement will require varying amounts of disassembly depending on the model. Typically, you will start by removing the drive belt and the drive wheels. The drive shafts will have a clutch on both sides of the mower that will need to be removed. There will be bearings or bushings where the drive shafts pass through the mower?s deck. Once the old transmission is removed you will want to carefully inspect the drive belt, the clutch assemblies, and the bearings or bushings. Replace any of these components that are worn. It is much easier to service these parts while you already have the drive broken down rather than waiting for them to fail in the future. Install the new transmission and the other components of the drive system. The parts breakdown for your mower is a valuable reference while reassembling complicated components such as the wheel clutches. Refer to it to help you make sure you install each part in the correct order. Once reassembled use the adjuster on the drive cable to properly tension the drive belt as needed.
