Length of the System: Hand Roll Irrigation System is available from 72M to 192M.
Covering Area: Irrigating area covered by a Hand Roll Irrigation System depends on length of farm, soil and climate. Refer to data in the table below:

Hand Roll Irrigation System: It is Side Roll without power unit, with max 156M length for small farms. It is easy to move by a single person without any difficulty. Hand Roll is useful for wheat, Barely, Alfa Alfa, Potato, Sugar-beet, Soybean, Grass etc.
Hand Roll is connected to Hydrant by 4” x 6M Flexible Hose.
The dimension of each pipe is 4” x 6M and it has one wheel with 193Cm diameter. In this case, the distance between ground and pipe will be 93Cm and sprinkler will be 110Cm high from the earth.
The distance between 2 Sprinklers is 12M, and the movement will be 3 turn of the wheels, which is 18M. Each sprinkler is mounted on the pipe by leveller for keeping its vertical position.
Hand Roll is an aluminum pipe (lateral) mounted on large wheels. The Hand Roll irrigates in place (does not move while irrigating), and it is moved from position to position between irrigation runs. An air-cooled gasoline engine provides the required power to move the aluminum sprinkler line across the field. The aluminum pipe is connected to hydrants by a flexible hose. The hydrants are usually spaced every 18 meters (60′) along the supply line (mainline). The supply line may be located along one edge or in the center of the field.
The Hand Roll is very simple to operate. When an irrigation run is finished, the operator simply turns off the mainline valve and disconnects the flexible hose. The drain valves automatically drain the pipe due to the reduced pressure. The operator then manually moves the line and rolls the pipe to the next hydrant position along the field, reconnects the flexible hose, turns on the water and starts the next irrigation run. The whole operation of repositioning takes about 20 minutes for a single person. When the Motoroll has reached the last position at the end of the field, it is driven back to the starting point for the next irrigation cycle.
