Abstract: Two sets of movable
lug wheel with spring mechanism for hand tractors have been designed and
tested. The wheels were set on local hand tractors and tested for tilling paddy
fields in Cianjur and Subang districts, West Java. A local fixed lug wheel was
also tested in each location. The movable lug wheel for Cianjur location was
equipped with a pair of coiled type torsion springs on each lug, while the
movable lug wheel for Subang location was equipped with a shaft type torsion
spring on each lug. Field performances: theoretical and actual field
capacities, wheel slip, and wheel shrinkage, were measured during the test. The
test result in Cianjur showed that the movable lug wheel had a better traction
performance than the fixed lug wheel. The average wheel slip of the movable lug
wheel was 11.54%, while the average wheel slip of the fixed lug wheel was
20.89%. Field efficiency of the movable lug wheel was 76.33%, which was bigger
than the fixed lug wheel (68.45%). However, the test result using shaft type
torsion springs in Subang showed that the spring mechanism did not work well,
and the spring mechanism should be modified on its torsion-shaft diameter and
welding strength.
