100 Ft Front-Mounted Sprayer
"Two 250 gal. Demco tanks are mounted on the front of a 2470 Case 4-wheel drive tractor. I built the booms from 2 1/2-in. steel pipe in a special truss configuration. Stainless steel nozzles along the bottom of the boom are fed chemical through 1 1/4-in. plastic pipe. The booms are hinged at each set of tandem caster wheels as well as at the end of each tank. A 3-in. hydraulic ram on either side lifts each boom. The outer 10 ft. of each end is swivel mounted and spring tensioned to allow for movement in case of misjudgement and to fold the segments up for transport.
"Each set of tandem 14-in. radial tired wheels is mounted in line with each other. Other equipment includes a 1 1/2-in. turbo centrifugal pump, a Demco cab-mounted boom selector with pressure gauge and control, an SED spray monitor and an Adja silver marker.
"The size of the boom can be reduced to incorporate herbicides by removing sections."
