Mastercut Parts

A V-belt is used on riding lawn mowers and yard tractors to turn the blades and the accessories of these power tools. The engine pulley, which supplies power, is connected to the cutting deck pulley, which turns the mower blades, with a V-belt. Over time the V-belt, which is made of rubber, may stretch, calling for the tension on the belt to be adjusted. Eventually the belt will wear to the point that it no longer turns the cutting deck pulley fast enough for the blades to cut grass. Sometimes the belt will crack with dry rot and break. In any of these instances, the solution is to replace the V-belt. In order to replace the V-belt, the cutting deck must be lowered completely. A worn belt will likely slip off the cutting pulley with little resistance. In case the belt is missing, the user will find a diagram with the proper V-belt routing on top of the cutting deck. When replacing the V-belt, make sure to use a genuine OEM replacement part such as this one, which is manufactured to be an exact replacement for the original. This V-belt is compatible with riding mowers from MTD, Murray, Huskee, Troy-Bilt, Yard Machines, and Yard Man.

This is a Briggs & Stratton Original Equipment 491588S Air Filter Cartridge. The purpose of this filter is to prevent dirt, dust, and debris from contaminating the carburetor and damaging the engine. This flat panel style, pleated paper air filter provides the first line of defense against the destructive effects of dirt ingestion. It is designed for 3.5 through 6.75 HP quantum engines and 625-1575 series engines. Over time, the air filter can get clogged or damaged, and this can lead to reduced engine performance. Locate the air filter cover, unscrew it, and remove the old filter. Make sure to clear out any debris that has found its way into the air filter assembly before inserting the new cartridge. Reattach the air filter cover and secure it with the screws. This replacement part works with generators, lawnmowers, pressure washers, wood chippers, and tillers.

This is a genuine replacement bolt that is designed specifically for use on select lawn tractors. This tractor bolt is a specialty piece of hardware designed for use on the steering segment gear. This screw holds the gear in place and is exposed to constant vibrations and repetitive motion as a result. Over time, that can result in damage, wear, or even total breakage of the bolt and require a replacement. If the bolt isn't functional or is missing, the steering segment gear will not be secured and that can lead to further damage if left unattended. Using a genuine replacement part like this will guarantee an exact fit for compatible models. This genuine OEM gear bolt is manufactured by MTD. It is compatible with lawn and garden equipment from RYOBI, HUSKEE, Troy-Bilt, Bolens, Yard Machines, Yard Man, and Cub Cadet, along with select models from MTD. The bolt works for more than 100 compatible models. It is made of durable metal and sold as an individual unit. A wrench or socket will be required to replace this part. Always wear gloves when performing repairs on lawn and garden equipment and allow the engine to cool before doing any work.

This is a genuine wing nut replacement designed for use in select walk-behind lawn mowers. Although some wing nuts are considered standard hardware on lawn mowers and other equipment, this specific wing nut connects to a bolt and secures the front baffle to the deck of the mower. Over time, this plastic wing nut can crack, fall off, or the threads may become damaged. This will result in the mover assembly being affected and the unit may not be able to be used until the nut has been properly replaced. This genuine replacement part will provide the exact fit for compatible mowers. This genuine OEM wing nut is manufactured to exact standards and comes from MTD. It can be used with hundreds of walk-behind lawn mower models from the brand, as well as those from Cub Cadet, Ryobi, Troy-Bilt, Bolens, Yard Man, Yard Machines, and Huskee. This plastic wing nut is sold individually. The carriage bolt that it connects to will need to be purchased separately if that also needs to be replaced.
