| 摘要 |
The invention provides a farm implement frame which includes a plurality of elongated generally planar and horizontal frame sections (2a, 2b) to which individual ground working tools may be mounted, extending transverse to the direction of travel when in the working position and including spaced apart forward and rearward members, and extending generally in the direction of travel when in the transport position, connected to elongated hitch members (18) for connection to a tractor or other motive source the center 2 of said frame sections; each including an inner end and a distal end, connected together at their respective inner ends by a main pivotal connection (3) adjacent the said forward members having a generally vertical axis so that the inner ends of said center frame sections about one another in the working position, each separately supported above the ground by first wheel means adjacent said inner end of said rearward member respectively, each also supported by said hitch members and by 2nd wheel means adjacent each said distal end, and, so as to remain generally parallel to the ground in the working position.
