Claim 13:
14. A sugar beet defoliator with scalping attachments, comprising:
a defoliator unit, moveable in a field in an operating direction, configured to remove foliage from beet tops; and
a plurality of beet scalpers, disposed at a row-width spacing in discrete groups on a rear portion of the defoliator, each beet scalper including
an upwardly spring-biased parallel arm linkage;
a scalper boom, having a lower portion supporting a beet scalping blade, and an upper portion attached to the parallel arm linkage; and
a locking mechanism, interconnected between the boom and the parallel arm linkage, configured to secure the boom in a downward operating position against the bias of the parallel arm linkage, and to release the boom to lift away from the operating position to a tripped position under force of the parallel arm linkage when a force opposite to the operating direction is applied upon the lower portion of the boom, causing the upper portion of the boom to rearwardly deflect an actuation amount.
