Automatic Windmill Shut-Off

Automatic Windmill Shut-Off ENERGY Wind Power 18-2-12 In an effort to conserve water, Texas farmer John Grabber came up with a simple automatic shut-off switch to mount on windmills used to fill stock tanks on remote pastures. He first attaches an L-shaped lever to the pull-down handle on a windmill and then hangs a 5-gal. bucket in the notch on the upper end of the lever. Then he runs a hose from the overflow pipe on the stock tank to the bucket so water flows into the bucket after the tank fills up. When the bucket fills up, it trips the lever, putting the pump out of gear. He uses the same system on electric pumps except that a 1-gal. pail is big enough to shut off a switch.
