Murray is an international power lawn equipment company that manufactures equipment like walk-behind mowers, snowblowers, and lawn tractors. In February of 2005, the company was taken over by competitor Briggs & Stratton Power Products after filing for bankruptcy. However, the Murray brand name is still applied to products in 2010. Owners of Murray lawn tractors can log onto the company's website to search extensive parts lists and replacement parts catalogues by tractor model.


Engines are one of the most important parts of any piece of power equipment. Tractor engines are responsible for creating the torque required to spin the blades for cutting and the momentum needed to drive the unit forward and backward. Since filing for bankruptcy, all Murray tractor engines are produced by Briggs & Stratton. Briggs & Stratton produces six series of tractor engines, three of which are for domestic use and three of which are for professional use. One such Murray riding mower engine series, the Power Built, has a displacement of 500 cubic centimetres, horsepower ranging from 15.5 to 19.5 depending upon the specific model and 1,419ml. oil capacity.

Gear Drive

Murray riding tractors are equipped with a gear drive, which is one large system composed of multiple small parts and is responsible for transferring gear changes from the hand control to the engine. Parts of the gear drive on Murray tractors, like model number 7800192, include nonoperative pieces like screws, washers, bolts, pins, brackets and plates, as well as moving parts, such as the lifter pivot, break lever and sector gear bearings. Static parts in the gear drive serve to create the framework within which the moving parts operate.

Grass Bagger

The grass bagger on Murray tractors, such as model number 33901, is a complex part composed of a number of smaller parts. Simply, the grass bagger is a network of pipes that use suction power to transfer all the materials chopped by the tractor's blades to a single container for cleanup. Parts of the grass bagger system include the grass bag itself, screws and brackets used to attach the bag to the body of the tractor, a wire used to give the bag a definitive shape, a weight for balance and a series of curved pipes through which grass passes before reaching the bag.

Mower Deck

Mower decks are the lawn tractor part responsible for doing the actual cutting. One such deck can be found on the Murray riding mower model number 403131. Located between the front and rear wheel axles, mower decks are complex parts that attach to the blades of a mower. Parts of the mower deck are responsible for transferring torque generated by the mower's engine to the blades for cutting. On riding mowers with adjustable blade heights, decks contain systems for raising and lowering the blades to meet the desired height of the user. Mower deck parts for Murray tractor 403131 include a number of screws, bolts and brackets, as well as cables, pulleys, extension and torsion springs and a steer ball.
