ABSTRACT:
A vegetable topper for cutting the leafy tops off of tubers, such as onions, after they have been uprooted from the field. The topper is mounted on a wheeled moveable frame towed by a tractor, which uses a vacuum to lift the tops and snip them off. The power for the vacuum fan and topping operation is derived from a power take-off of the tractor. The shearing means comprises a linearly reciprocating sickle blade whose height relative to the oncoming tops is optimally predetermined for a shearing type of cut for varying sizes of onions, providing maximum efficiency. The sheared tops are substantially mulched into fine particles within a fan in the vacuum system and dispersed to the side of the topper. A conveyor system lifts the untopped onions into proximity with the fan and sickle blades and consolidates already topped onions into a reduced area. Two pick-up conveyors lift up the untopped onions and a funnel-shaped rear chute delivers the topped onions back to the ground, resulting in a reduced gathering area. Remotely steerable rear wheels provide enhanced turning capability.
