Modification and Performance Test of Final Drive Power Transmission System for Jacto Self - Propelled Sprayer

Abstract

The experiment was conducted at AGADI Blue Nile State rainfed sector. The main objectives of this study were the modification of the transmission system in JACTO self propelled spraying machine and the performance test of the sprayer. To avoid the frequency rupture of the transmission chain from the drive shaft to rear axle another chain and two sprockets were added to the system to enforce it The results obtained from this modification showed that the modified sprayer when operating with two chains and sprockets cover an area of about 3000to 4000feddans without any brake down whereas and the area covered was about 1000 to 1200 feddans when using a single chain after this period the chain was subjected to break down The other factors measured during the sprayer were field performance test such as fuel consumption, field efficiency and slippage no significant difference were recorded when compared with the sprayer before modification
