Much labor is required to irrigate cropland with conventional
methods and equipment. The scarcity and high cost of good farm labor
generally results in inefficient irrigation with the result that the crops
either receive insufficient water or that too much water is used, resulting
in a waste of that sometimes rare commodity.
Accordingly, one object of this invention is to provide means for
automatically opening a gate in an irrigation ditch. Another object is
to provide means for so opening the gate at a predetermined time. Still
another object is to provide means for automatically reclosing the gate
and resetting the release mechanism when the water has run out of the
ditch. These and other objects that will be obvious to those skilled in
the art are achieved by means of the invention described below
