Wheel Moves are an irrigation system which moves through a field, from one set position to another, under its own power. The primary element of this system consists of the lateral wheel line, the power mover and the mainline.
Wheel Move Features:
How a Wheel Move works:
The lateral torque pipe, also called the lateral wheel line, is composed of a 4 or 5 inch diameter (101.6mm or 125mm) thick-wall aluminum irrigation pipe. The torque pipe functions as an axle to move the entire system and as a pressurized water-delivery for irrigation purposes.
Each section of pipe has one wheel attached at its center, and connects to the wheel move with a special Torque Coupler and clamp band. Connect as many lengths of pipe as needed to cross a field up to a half mile or .805km.
At each torque coupler joint is a rotating impact sprinkler head and a Self Leveler which automatically keeps the sprinkler head in a steady upright position.
The power mover is an air-cooled gasoline engine geared to rotate the pipe and wheels. The mover is positioned located in the center of the rolling wheel line. This allows the entire wheel line to be moved across a field by one person.
Water is provided to the wheel line through a mainline which runs perpendicular to the wheel line. The mainline is located at the center or along one the edge of the field. Every 50 to 60 feet (15.24m or 18.29m) along the mainline are outlet valve stubs. Flexible pipe or hose is attached to the stub valves, connecting the water source from the mainline to the wheel line.
Once the assembled wheel move is placed in the field, a flexible connection is attached between one end of the lateral wheel line and the first mainline outlet valve. The water is then turned on with a special Valve Opener and the first section of the field is sprinkled for the required amount of time (determined by the crop and soil).
Moving the Wheel Move
When it is time to move the wheel line to the next mainline outlet (50 to 60 feet away),close mainline valve and allow the lateral line to automatically drain itself of water via pressure activated Flapper Type Drain Valves located at each pipe connection.
A WHEEL MOVE MUST NEVER BE MOVED WITH WATER IN THE LATERAL PIPELINE.
Disconnect the water source and star power mover. The entire wheel line is driven down the field to the next mainline valve position. At the next valve, reconnect the flexible water source. The water pressure automatically closes the Drain Valves, and the sprinkling procedure is repeated.
Once the wheel line reaches the end of the field, the operator reverses the power mover and driven the entire distance back to the beginning of the field where the cycle is repeated.
