摘要

#CMT# #/CMT# The potato harvester has front (2') and rear (2) frame sections, each of which carries running gear, one set of which is driven by an engine mounted on the front section. A transfer section extending across both parts of the frame feeds potatoes from the harvesting device to the store. The two sections of the frame are connected by a ball and socket joint (18) and a swivelling arm (19) with pivots (20, 21) at each end. These allow the frames to be swivelled about a perpendicular axis and a longitudinal axis. #CMT#USE : #/CMT# Potato harvester. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows the joint system. 2' : Front section of frame 2 : Rear section of frame 18 : Ball and socket joint 19 : Swivelling arm 20, 21 : Pivots.
