This is lateral move system or linear system. All the machines work in linear movement by motor driven tires to irrigate rectangle area. Unlike center pivot systems, where the area irrigated depends only on the length of the machine, lateral system area is determined by two factors: system length and travel distance.
This system is mainly used for grasses, grains, vegetables, cotton and sugar cane crops. The length can be from 1 span to 18 spans, normally more than 7 spans system is economical. Lateral move system is the only machine which can irrigate all land. In square land, all spans are parallel with the land, no blind angle. The irrigation ratio can increase to 99%.
Water source to fill the machine can be canal, concrete ditch, rivers and pond. It is not allowed to operate the machine without water.

Ditch feed
- Benefits of Lining a Ditch
- Conserve water (e.g. reduce friction loss and seepage loss from earthen ditches)
- Minimizes irrigation-induced erosion and invasive weed growth
- Work well with a gravity system; No pumping is required
- Maintenance minimal compared to a dirt ditch
- Can work on any field, regardless of shape and be tailored to site-specific conditions
Hose feed
- Electric power provided by cable or genset
- PVC material, UV resistant
- Diameter from 4 to 12 inch
- Work pressure from 4 to 10 bar
Auto reverse
- Prevent crashes
- Stop machine from any tower
- Provide additional safety
- Package includes control box, sensing arm, cable, spring, traverse arm
Construction
