Description

Side-roll wheel-move systems have large-diameter wheels mounted on a pipeline, enabling the line to be rolled as a unit to successive positions across the field. Crop type is an important consideration for this system since the pipeline is roughly 1 metre above the ground.

 

Advantage and limitations

  • Adaptable to irrigating potatoes, vegetables, field crops, and alfalfa hay.
  • Low labour requirement.
  • Higher initial costs and maintenance costs then hand move laterals.
  • The field must be rectangular.
  • Not adapted to tall crops.
  • Topography must be flat or gently rolling.
