An irrigation control system includes a rotary water motor which receives water from a valve, which has either a full on or a full off condition, depending on the alignment of an associated irrigation line. A pilot valve which is not susceptible to being clogged by contaminants that can be found in the water actuates the valve to the on or off position for controlling the water motor.

Irrigation control system

An irrigation system includes an irrigation line and a wind brace assembly which can be automatically disengaged from the irrigation line preparatory to moving the irrigation line across a field to a new position. The assembly is automatically engaged with the irrigation line in the new position to prevent wind from moving the irrigation line.

Irrigation line wind brace

An irrigation control system includes a rotary water motor operatively associated with valves to provide that the water motor is either in the full on or full off condition, dependent upon alignment of the irrigation line. The irrigation control system also includes a rotary water motor operatively associated with a valve, and a shut-down system is included for closing such valve upon loss of water pressure in a safety line.

Irrigation systems control

An irrigation system includes an irrigation line mounted on wheels which may be turned from positions perpendicular to the line, where they serve to move the irrigation line across a field in a direction perpendicular to its length, to positions parallel to the line, wherein the line may be towed lengthwise to another location. Movement of such wheels provides for appropriate engagement and disengagement of gear means through which drive is provided to the wheels.

Drive means for irrigation system

Disclosed herein is a mobile transport assembly which may be moved to adjacent an irrigation line, and which includes means for selectively applying rotational torque to such irrigation line at an area between the ends of such irrigation line, to in turn rotate and transport the irrigation line. The mobile transport assembly may then be moved from such irrigation line after the transporting thereof to another irrigation line to in turn move that irrigation line by applying rotational torque thereto.
