Roto-Rainer is Labour Efficient:

The Roto-Rainer irrigator can be set to run in any chosen direction. With the machine pulling up to 300 m length of hose; with central hydrant outlets, a 600 m run can be achieved.

When operating in strong windy conditions, coverage is still very good as the water is carried in the boom almost to the end of the water circle, and because the boom rotates a very efficient watering pattern is achieved.

Roto-Rainer's Performance:

The model 125 Rotary Boom has a maximum flow rate of 42 l/s with a run length of 400 m; 113 mm gross can be applied to 3.0 Ha in 23 hours. If shifted twice a day 54mm can be applied to 6.0 Ha
