Abstract

A folding frame farm implement comprising: a) a cart (21), b) a multi-section rockshaft frame (20) mounted on said cart and oriented generally transversely in the working position, c) said rockshaft frame (20) having a central section (20c) and laterally disposed wing sections (20a, 20e), d) wheel means (2, 3) supporting said rockshaft frame sections, e) said rockshaft frame sections being rotatable about a generally transverse axis between a lst position and a 2nd position, f) a plurality of individual tool frame sections (27, 28) rotatably mounted to corresponding ones of said rockshaft frame sections about a generally transverse axis, g) individual wheel support means (29, 31) for each tool frame section, h) wherein said tool frame sections (27, 28) are supported at working positions and a non-working position at a variable height above the ground determined by the relative rotational position of the rockshaft frame (20) between said lst position and said 2nd position and by the said wheel support means (29, 31), i) central tool frame section support means (31) associated with said central rockshaft frame section adapted to retain said central tool frame section (20c) in close proximity to the ground for transport, j) lift means to further rotate said wring frame tool sections (20a, 20c) from a generally horizontal position to a raised position for transport and k) said wing sections (20a, 20c) being foldable rearwardly for transport.
