There are groups that the snow blower parts can be divided into, from the engine, blower and drive systems to the chassis components, controls and optional parts. Large snow blower parts, such as the auger, are often used in conjunction with small parts, such as a bearing. These parts can create a system that offers the user a dependable and reliable snow blower.
One of the most notable of all the snow blower parts is the main chassis. This consists of the metal framework that all of the other components are attached to. On top of the chassis is the engine. Most snow blowers use a gasoline engine to power the machine through the snows of winter. The engine is actually a collection of snow blower parts, including the fuel tank, carburetor and the drive pulleys; working in unison, the engine parts group provides the power for the movement and removal of the snow.
Mounted inside of the chassis is the drive system, a collection of snow blower parts that includes the drive axle, clutches and drive belts. All of these parts are designed to receive mechanical power from the engine via the drive belts. Some snow blowers incorporate a power steering system that is controlled by squeeze levers mounted on the handle bars. The handle bars are attached to the chassis and provide a means of controlling the unit. Gear selectors, throttle controls and the snow blower clutch are all located on the handlebar unit and place the operating controls in easy reach of the user.
At the front of the chassis is the snow intake scoop and auger system. Shaped much like a large funnel, the intake scoop protrudes out and away from the chassis so that is can be plunged into the snow. Inside the scoop and mounted horizontally is the intake auger. The auger is driven by a belt running off of the transmission and pulls snow into the scoop as well as breaks up hardened snow so that it can be blown away. The snow is fed into the blower unit by the auger, as well as by the continuing forward motion of the machine as it travels along its directed path.
The blower unit is unique to two-stage snow blowers and consists of a paddle mechanism that is driven off of the engine. As the augers push the snow into the blower unit, the snow is directed up and out of the machine through the blower chute. Other snow blower parts, such as the chute control lever and the flap control, are used to direct the blown snow both up and down as well as left and right.
