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
