There are several types of wheels used on cotton pickers, each serving a specific purpose in the harvesting process:

1. wheels: The drive wheels are located the rear of the cotton picker and are responsible for propelling the machine forward or backward. These wheels are typically powered by the engine or motor of the cotton picker and provide the necessary traction to move the machine through the field.

2. Steering wheels: Steering wheels are located at the front of the cotton picker and are used to control the direction of the machine. They allow the operator to steer the cotton picker and navigate around obstacles or through the rows of cotton plants during the harvesting process.

3. Gauge wheels: Gauge wheels are adjustable wheels that help maintain a consistent height for the picking unit or headers of the cotton picker. They help prevent the machine from running too low or too high over the crop, ensuring proper picking and minimizing plant damage.

4. Transport wheels: Transport wheels are larger wheels located on the sides of the cotton picker, typically used for moving the machine between fields or on roads. These wheels provide stability and support during transport and help distribute the weight of the cotton picker evenly.

5. Double wheels/ Dual wheels: Some cotton pickers may be equipped with double or dual wheels on each axle to provide additional traction, flotation, and stability when operating in challenging field conditions or on rough terrain.
