This control handle is designed specifically as a replacement for use on select walk-behind lawn mowers. The control handle is the safety that is engaged to allow the engine to run. When holding the control handle in, the pull start can be activated and the engine will run. Once the control handle is released, the engine will stop. In the event that the control handle becomes damaged or fails, it will need to be replaced so that the mower can continue to be used. This handle can provide a genuine replacement for compatible models. This control handle is manufactured to exact standards by MTD and provides an exact fit. It is compatible with hundreds of models, including select models from RYOBI, Yard Machines, Troy-Bilt, Yard-Man, Husky, Bolens, and Cub Cadet. This part is also known as the control bar, control handle, engine stop handle, bail control, or mower bail. It is made of durable metal and sold individually. No tools are required for the installation of this part. To replace the handle, simply squeeze the existing control handle to remove it from the outer handle, and then align the new handle and slide it into place. When properly installed, the pressure will hold it in place and allow for proper operation.

This replacement part is a center sprocket. This is a genuine replacement part made by MTD. This part is used to connect certain pieces and use a turning or rotating mechanism to allow the engine to run properly and effectively. A new center sprocket might be needed if the current one has worn ridges. This can be due to a high level of friction after years of normal wear and tear. Because of the rotating motion, this part can be easily stripped over time and will need to be replaced. Wear work gloves during this repair to prevent injury to the user and those around them. This is a genuine OEM replacement part. This part is sold individually and is sourced directly from the manufacturer.

This kit includes a replacement debris shield designed to mount beneath the mower deck around the blade area. The shield helps contain grass clippings, dirt, and small debris during mowing to protect the operator and nearby objects. Replace this shield if it is cracked, bent, or missing, which can result in debris being thrown from under the deck.

An idler pulley is an essential part of many small and medium sized gasoline powered tools. This idler pulley is used in equipment such as tillers, lawn tractors, log splitters, edgers, snow blowers, and trimmers. The idler pulley is necessary so that the engine can run without the tool's moving parts being engaged. For instance, a lawn tractor running without the cutting blades turning or the wheels rolling. Once the idler pulley is engaged, the blade begins to turn. There is a great deal of resistance encountered by the idler pulley each time the equipment's tools begin to turn. Over time, the pulley can become worn and will eventually need to be replaced. If there is a squealing sound whenever the moving parts of a lawn tool are engaged, it is probably a sign that the idler pulley is about to fail. The pulley itself is attached to the engine housing with 9/16 hex bolts and requires an adjustable wrench and 9/16 ratchet to remove and replace. Always use a genuine OEM manufactured replacement part such as this one when replacing the original, as this part is identical to the original. This part is compatible with equipment manufactured by Bolens, MTD, Cub Cadet, Huskee, and Troy Bilt.
