Abstract
ABSTRACT THE performances of two types of prototype potato harvesters were investigated. One was fitted with a primary web (chain) delivering to a secondary web which was agitated horizontally, either parallel or perpendicular to the direction of travel. Agitation perpendicular to the direction of travel gave up to 30% better clod break-up, but 13 to 23% higher damage than agitation parallel to the direction of travel. The other machine embodied a variable area primary web, agitated vertically or horizontally. Tests indicated that horizontal agitation can improve sieving and reduce potato damage by 17% to 30%. Varying the effective sieving area can improve efficiency of clod break-up and soil loss, without the need to change from the optimum web/forward speed ratio. Doubling the web area with vertical agitation reduced clod by up to 37% and increased the damage index by up to 33%.
