- Abstract
Existing manual hoes are dynamic push-pull weeders, but their designs are based on static force exertions. A test rig was developed to optimize the speed and force exertions. At 1.0 km h-1, an operator can exert 20 to 25 kgf. Based on optimized results V-shaped blade (V) and straight blade (S) weeders were developed and evaluated along with the existing twin wheel hoe (T). Performance of the V and S weeders was higher than T. The field capacities were 0.026, 0.033 and 0.33 ha h-1 and energy expenditures were 20.35, 18.82 and 18.78 kJ min-1 respectively, for T, S and V; however V was best amongst the three.
