Abstract
A wing packer has a middle frame section and two wing frame sections to which rollers are attached. The packer can be converted to a transport position by a hydraulic system which lifts the middle section and pivots the wing sections upward. The rollers are connected to the frame about a two-axis pivot which facilitates their remaining in contact with the ground on uneven terrain.
