| Abstract | A bow shaped e name l coated float attachment of size 110 cm x
65 cm x 10 cm was developed for 4 . 74kW K80 Kubota power tiller.
The power tiller was equipped with standard cage wheels of size 60
cm diameter , 24 cm width with 3 0 degrees lug angle and lug spacing.
During the general performance test it was observed that the float
prevented the cage wheel from digging the soil deeper when s lippage
occurred. The float- cage wheel combination eased the operator ' s
work. It was possible to release the power tiller from stagnant
position by sledging.
The performance of power tiller with and without float on it
was evaluated in flooded and puddled field conditions. It was
observed that there was no significant difference in the pull and
power delivered at different s lips by power tiller with and without
float attachment in f loaded soil condition. However there was
significant difference in pull and power delivered by power tiller
in puddled field condition .It was because the cage wheels were
prevented by the float to reach the hardpan layer to develop enough
pull and power. The drag test of power till e r with a nd without
float showed that the presence of a float on a power tiller did not
increase the drag force required to pull it. In general the float |
