This replacement part is a hex screw, and it is intended for use in different types of lawn equipment. This is a genuine replacement part made by MTD. This screw can be used in a variety of ways depending on the repair needed. Hex screws are similar to normal screws except they have a six-sided head, like a hexagon. A new hex screw might be needed if the current one is damaged or missing. It is common that screws may become stripped or loose overtime, causing them to fall out. If any parts of the lawn mower are becoming loose or falling off, the hex screw might be missing. This replacement should be fairly easy and should only require a screwdriver and possibly pliers. This part is a genuine OEM replacement part and is sold individually. Be sure to purchase the correct amount as some appliances require more than one hex screw.

A ball bearing is a rolling element bearing that uses balls to maintain the separation between the bearing races. This part is designed for use with outdoor lawn and garden power equipment such as snowblowers, chippers, shredders, and tillers. It is compatible with products by brands such as Craftsman, Cub Cadet, Ryobi, Troy-Bilt, Yard Machines, MTD, Huskee, Montgomery Wards, Bolens, Yard-Man, and MasterCut.The ball bearing part is crucial because its purpose is to reduce rotational friction while supporting radial and axial loads. Without functioning ball bearings, valuable outdoor equipment would fall apart and quickly stop working. That is why it is important to get any ball bearings replaced if they are worn out or malfunctioning.This ball bearing is made out of metal. The ball bearing is an original OEM part sourced directly from the manufacturer, MTD. It is sold individually.

This ball detent is a genuine MTD replacement part for appliances operated by small engines, including lawn tractors, lawn mowers, snowblowers, leaf blowers, chipper shredders, and tillers. The function of a ball detent is to temporarily keep two parts in place relative to one another, as one or both of the parts rotate.A ball detent might have to be replaced in the event that it suffers damage over time or is lost or misplaced. It is possible for ball detents to fall out of their spot, meaning that the parts that it ordinarily holds in place will not be able to rotate properly. Additionally, a ball detent might have to be replaced if there is material deterioration. If this occurs, a replacement ball detent part should be ordered and secured to the small engine appliance immediately. Remember to always wear gloves when handling, repairing, and operating outdoor equipment. This ball detent is compatible with the following brands: MTD, Yard Man, Yard Machines, and Troy-Bilt.

This part is a replacement spacer. This is a genuine OEM part made by MTD and has been sourced directly from the manufacturer. This part can be used to replace a defective or worn-out spacer in a variety of tiller models. Spacers help to ensure that there isn't excessive heat, friction, or vibration caused by moving components within the tiller. They are particularly subject to wear and tear over time or with regular usage, and thus may need to be replaced with a genuine OEM part. When working on or near an engine, it's important to ensure that the equipment is powered off and completely cool before beginning any repairs. For more accurate information on how and where to place this spacer, the appropriate owner's manual and equipment diagrams should be referred to. As an authentic replacement part, this spacer is suitable for use on tillers that have been manufactured by MTD, Craftsman, Troy-Bilt, and other brands. Please note that this is a genuine part made of high-quality, durable metal and is sold individually.
