ABSTRACT:
A baler has a mobile frame adapted to move across a field, means on said frame operable to receive and form crop material into bales, a pickup assembly including pivot means on said frame and pickup means disposed generally forwardly of and swingably mounted to the pivot means and operable to pick up crop material from the field and feed it to the receiving and forming means, and improved means to counterbalance the pickup means. The improved counterbalance means includes a lever pivotally mounted at one end on said frame above the pickup means at a location spaced inwardly from one lateral side of the pickup means and extending generally parallel with the pickup means to an opposite end located generally above the one lateral side of the pickup means, a cable interconnecting the one lateral side of the pickup means with a lower portion of the opposite end of the lever and a pair of tension springs interconnecting an upper portion of the opposite end of the lever with the frame between the one end of the lever and an opposite end of the pickup means so as to substantially uniformily counterbalance a substantial portion of the weight of the pickup to enable the pickup means to flotatively follow the field contour.
