Linear or lateral move systems are similar to centre pivot systems, except that the towers move in a continuous straight path across a rectangular field (see pictures). The system moves (back and forth) in one straight line to cover either a square, a long rectangular or L shaped fields (see picture). Linear systems become economical when the field length is 1.5 to 3 times the width. Water is fed into one end of the linear move system by either hydrants or directly from a canal with a pump on the end of the line. Generally they have their own power source (i.e. motorized pump) mounted at the main drive tower. They can be towable too similar to the centre pivots. Wheels can be rotated by 90º for moving the machine from one field to another (see picture).

The flexi hose type needs a relatively flat, uniform, dry road for the hose pull cart for proper guidance and traction. Hose sizes are between 75 -150 mm  and the lengths are between 100-260 m. The flows are ranging from 70 - 260 m³/h.

The ditch/channel type can use an earth or concrete ditch or channel. The earth ditch should have a top width minimum 3.30 m, batter angle 45⁰ and the minimum base with of 0.90 m. Depth should be a minimum 1.20 m.  The concrete ditch should have a top width minimum 2.20 m, batter angle 45⁰ and the minimum base with of 0.30 m. Depth should be a minimum 0.75-0.90 m.

In order to follow the right track, a straight  V shaped trench/furrow, buried electric cable or above ground guidance cable is needed. All three types should be surveyed perfectly from end to end. Wheel tracks must be straight and a maximum depth controlled (see pictures). The alignment of the tower is really essential, because there is no fixed point, the entire system will stay off line if the alignment is not perfect.

Sudden or extreme terrain changes should be avoided because they can cause excessive compression or tension and guidance irregularity. Linear systems are more adaptable to lower pressures on heavier soils. Sandy soils also suited to these systems.
