Abstract
Abstract A grape gathering machine is provided in the two longitudinal travellers which are adapted to move away from or closer to each other. Swinging beater frames and swinging recovery frames are pivotally mounted on each of said travellers to define a pair of tunnels. The two tunnels enclose two adjacent rows of vine stocks from which the grapes are thus gathered simultaneously. The chassis of the machine may be raised and lowered between a road travel position and a grape gathering position respectively and may be supported solely by small intermediate auxiliary wheels to provide a small turning radius.
