Abstract

The force characteristics on the tilling wheel of the float-assist was studied in a soil bin at varying depth of cut and forward speed. The tests were conducted at 8cm, 10cm and 12cm depth of cut and 1kph, 1.5kph, and 2kph forward speed. Maximum draft, torque, and shaft speed were obtained from the tests. The puddling index, specific energy, performance index axle power, drawbar power and tractive efficiency for each test were computed. In all passes, the highest (94,64 N-m) torque was determined on first pass with 12cm at 1.5 kph and the lowest (10.10 N-m) was attained with 8 cm at 1 kph of second pass. The highest (265.35N) draft force for all runs was obtained with 8cm at 2kph of the second pass. For all the passes, the highest value for the axle power (1216.01W) was attained with 12cm at 2kph of the first pass while the minimum was 88.12W which was observed with 8 cm at 1kph of the second pass. among all the runs, the highest drawbar power calculated is 165.84W which is achieved with 8cm at 2kph of first pass.
