Build Your Own Mini Spray Rig
University of Kentucky agricultural engineers have developed plans for a self-propelled mini spray rig you can build yourself with new off-the-shelf components for around $2,000. Used parts, or scrap steel, would lower the price even more.
"Anyone who has the basic skills to repair his own farm equipment can easily build this sprayer," says George Duncan, who developed the plans with research associate Billy Tapp. He explains that the sprayer was primarily designed for smaller farmers and large gardeners.
Features include a 3-wheel frame, an 8-hp. engine, 3 speeds forward and 1 reverse, separate foot-operated clutch and brake pedals, hand-operated throttle, 30-gal. spray tank, and a 4-row fold-away boom that adjusts in height from 20 to 72 in. The tube-steel frame forms an "arch" over the row so that two wheels ride in line on one side of the row and the other wheel rides down the other side of the row. Adapts to rows from 36 to 46 in. wide.
Detailed plans include more than 50 pages of drawings, instructions and material listings.
