Design and Development of an Off-Set Rotary Cultivator for Use with a Two-Wheel Tractor for Fruit Tree Cultivation

摘要

An off-set rotary tiller for use with a basic Thai design two-wheel tractor was designed and developed for cultivating an orchard. Results from the test with 7 kW two-wheel tractor in a mango orchard with 178 rpm rotor speed and 1.8 km/h travelling speed indicated a field capacity of 0.12 ha/h with 92 % weeding efficiency. After the test, soil properties appeared to be 23.49 mm in clod diameter with 0.96 g/cc in bulk density and 371.41 kPa cone index on the-average.
