ABSTRACT:
A vegetable topper for cutting the leafy tops off of tubers, such as onions, as they lie in the field. This improved topping system is designed to be 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 supplied by a primary motor mounted on a wheeled frame, or derived from a power take-off of the tractor. The shearing means comprises a linearly reciprocating sickle blade whose angle relative to the oncoming tops may be adjusted for an optimally perpendicular shearing type of cut, 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 consolidates already topped onions with a first conveyor picking up a portion of the topped onions and a second conveyor delivering said portion over the remainder of the topped onions, resulting in a reduced gathering area. Remotely steerable rear wheels provide enhanced turning capability. Lifting the front of the topper relative to the ground further maximizes maneuverability, and adjusts the cutting of the tops.
