Scotts is a brand of lawn mower that was produced by John Deere. The brand was in production during the late 1990s and early 2000s and is no longer available as of 2010. Despite the brand being out of production, John Deere maintains a full complement of Scotts mower parts lists and manuals on its official website for reference. Scotts mower parts include cutting decks, controls, fuel and air system components and the engine and all related mechanical parts.

Engines are integral to any piece of power equipment, Scotts mowers and tractors not excluded. Engine parts like the crankshaft, cylinders, cylinder shafts and gaskets generate the power that propels the mower and rotates the blades. Walk-behind mower engines are connected to a manually operated throttle and choke system that, when triggered by the user, injects fuel into the engine to initiate the combustion process. Electrical systems perform this function on lawn tractors, connecting the ignition to the engine. Small engine parts such as screws, washers, nuts and bolts are used to affix engine parts to one another.
Cutting Deck and Chassis
On walk-behind Scotts mowers, the body of the unit and the cutting deck are one and the same. The cutting deck is the portion of a mower that holds and houses the blades. Blades are housed on walk-behind mowers underneath the cutting deck while the engine sits on top of the cutting deck. A pulley connects the pair and translates the power of the engine to the blades. On lawn tractors the cutting deck and blades are suspended from the underbelly of the chassis, which is a fancy word for body and indicates the outer shell of a riding mower that encases all the working parts. Nuts, bolts, screws, washers and other small static parts affix mechanical parts to the chassis.
Controls on Scotts lawn tractors include the steering wheel, adjustable cutting height lever, acceleration and deceleration pedals and brakes. Steering, speed and braking controls are connected to the wheels of riding mowers via the drive shaft, axles and transaxle. The driveshaft is a shaft that translates steering commands to the wheels. Axles are poles that rotate the wheels. The transaxle is a mechanical part that translates engine power from the front wheels to the back wheels. Walk-behind Scotts mower command parts include the control bar, which, when squeezed, accelerates the mower and, when released, stops the mower, and the various levers that allow users to manually adjust cutting height, handle height and blade operation.
Fuel and Air
Fuel and air components on both walk-behind and riding mowers produced under the Scotts aegis help perform essential engine functions. For successful engine combustion to take place, the correct ratio of air and oil must be present in the engine. The carburetor is a riding mower engine part that helps insure this ratio. On walk-behind mowers the choke and throttle perform this function. The primer bulb is a walk-behind mower that injects fuel into the engine before the choke is triggered to facilitate combustion. Vents on both walk-behind and riding mowers protect against over heating in the engine.
