Abstract
An implement is provided that includes a frame, a ground engaging roller mounted to the frame, and a suspension system that includes a spring for biasing the roller toward the ground, and a frame support member fixed to the frame above the roller. The frame support member prevents the implement from experiencing high forces when moved into the transport position or when a strong downpressure is exerted on the frame by transferring the forces through the ground working tools to the ground. The frame support member can be a rigid protrusion, a flat plate, or a rolling element. In preferred embodiments, the implement is an agricultural packer and frame support members are positioned above each roller.
