ABSTRACT:
A pivot or circle type irrigation system has a single hydraulic cylinder upon each vehicle to provide motive force to that vehicle. Two hydraulic tubes extend the length of the system and each hydraulic tube is connected to one side of each cylinder without valves. The cylinder movement is blocked if the vehicle upon which it is mounted is detected to be ahead by an alignment system. Hydraulic fluid is pumped into one tube until an increase of pressure indicates that all of the cylinders are cockablock and then the tubes are reversed and hydraulic fluid is pumped into the other line until, again, a rise in pressure indicates that all of the cylinders are cockablock.
