Development and performance evaluation of engine operated walk type sprayer

Abstract

A Engine operated walk type sprayer machine was developed in the Department Farm Machinery and Power Engineering, D. Y. Patil agriculture and technical University, Talsande, Kolhapur. The developed engine operated walk type sprayer was tested on the experimental field for optimization of the operating parameters for brinjal and wheat crop. The speed noted 3, 3.5, 4 km/h and width of operation 2.6, 2.8, 3 m. The quantity of the chemical solution after the calculation was 178 l/ha. The fuel consumption rate was 1.5 l/ha. Average Theoretical Field efficiency is 0.98 ha/h. Average effective field capacity is 0.95 ha/h. Field efficiency is ratio of effective field capacity and theoretical field capacity. Average field efficiency is 90.11%. Fixed cost is 26.75 ₹/h, Variable cost is 229.25 ₹/h, total cost is 256 ₹/hr. Break-even point of the sprayer was 9.09 yrs. Overall, in operation and economic point of view the Developed engine operated walk type sprayer was found satisfactory performance.
