DESIGN, FABRICATION AND TESTING OF A MOTORCYCLE MOUNTED HERBICIDE BOON SPRAYER

Abstract

A motoreycle mounted herbicide boom sprayer with a capacity of 2 ha/hr was designed and fabricated in on overcome some of the challenges associated with the existing equipment for weed control such as knapsteck spl tractor mounted boom sprayer etc. The machine was fabricated from locally available materials and comprises following parts: battery, spray pump, tank, hose, boom, nozzles and frame. Test results indicate that at 8, 10, 1 14 km/hr ground speeds, the spray application rates were 286, 270, 256 and 245L/ha respectively whi corresponding field capacities in ha/hr are 1.5, 1.8, 2.1 and 1.8 respectively. The field efficiencies obtained four different speeds are 78.2. 76.1. 72.1 and 75.4% respectively. Maintenance and replacement of parts used i since all the components are available locally.
