AGRICULTURAL MACHINES WITH IMPROVED FOLDABILITY OF ITS LATERAL FRAMES

abAgricultural machine with lateral folding frames (′) and a central frame having plates linking same to a fixed tongue placed on the machine's longitudinal symmetry axis.To said plate are articulated arms, coplanar to and. Each free end of arm is connected to its respective lateral side frame (′), and on each arm is articulated on a respective hydraulic piston whose other end is articulated in to a telescopically displaceable tongue section (′).The containers or hoppers are arranged on the support area provided by the running gear linked to the central frame and portion of fixed tongue.The hydraulic pistons achieve the folding of the lateral frames (′) to a travel disposition, offering said machine in its folded condition a minimum width less that 4 meters, compatible with the road travel regulations.
