WORK CAPACITIES AND FUEL CONSUMPTIONS OF HAND TRACTORS MANUFACTURED IN THE PHILIPPINES.

Abstract

Field performance data show the actual plowing capacity ranged from 0. 098 ha/h to 0. 25 ha/h with an average of 0. 14 ha/h (or 7. 86 h/ha) and the field efficiencies ranged from 53. 6 to 94. 4% with an average of 83. 6%. Six of the hand tractors tested were gasoline-fed and the average fuel consumption was 2. 491 l/h (18. 73 l/ha) and a specific fuel consumption of 1. 89 l/ha/hp. On the other hand, the four diesel-fed hand tractors had an average fuel consumption of 0. 82 l/h (6. 12 l/ha) and an average specific fuel consumption of 1. 22 l/ha/hp. Obviously, the hand tractors with diesel engines have lower fuel consumption which will offset in the long run their high initial purchase cost.
