Abstract: The ground wheel in seed drills and planters works as a braked wheel. The braked wheel experiences negative slip (i.e. skid). Excessive value of skid will result in alteration of spacing between hills. Skid increases with the increase in braking torque resulting in large variations in hill to hill spacing. Hence, the relationship between braking torque and skid is important for the designing of seed drills and planters. The relationships between pull, torque and slip characterizes the behavior of the braked wheel. An experiment was carried out to determine skid at different lug height (15, 20, 25 and 30 mm), different axle load (98.1, 147.15 and 196.2 N) and different torque and it was found that there was a little effect of axle load on skid. Expected value of skid at different values of lug height and braking torque was calculated from the regression equation. This was used for determining lug height when torque requirement and permissible level of skid were known. It was found that skid increases with decrease in lug height almost for all values of braking torque. At 15 mm minimum lug height, skid increased with braking torque rapidly. The variation in torque with skid was comparatively less at maximum lug height of 30 mm. The increase in braking torque was not constant with respect to the increase in skid value. The maximum skid was 32.4 percent at the maximum braking torque of 17.14 N-m, minimum lug height of 15 mm and additional axle load of 20 Kg.
