In one embodiment, an in-line tandem axle assembly comprising: a tandem wheel arm; a pair of wheel connecting assemblies, each comprising a hub and a spindle; a pair of mounts coupled respectively to the pair of wheel connecting assemblies; a pair of wheels coupled respectively to the pair of wheel connecting assemblies, the pair of wheels separated by the tandem wheel arm and in a same fore-and-aft position; and plural pairs of parallel links of equal length pivotably mounted to the pair of mounts and pivotably mounted to the tandem wheel arm.

In-line tandem axle assembly

In one embodiment, an in-line tandem axle assembly comprising: a tandem wheel arm (); a pair of wheel connecting assemblies (A,B), each comprising a hub (A,B) and a spindle (A,B); a pair of mounts (A,B) coupled respectively to the pair of wheel connecting assemblies; a pair of wheels (A,B) coupled respectively to the pair of wheel connecting assemblies, the pair of wheels separated by the tandem wheel arm and in a same fore-and-aft position; and plural pairs of parallel links (A,B) of equal length pivotably mounted to the pair of mounts and pivotably mounted to the tandem wheel arm.

An implement comprising a center section and a pair of wing sections, each of the sections comprising a pair of parallel frame members pivotably coupled to each other, wherein one of the frame members comprises a toolbar; and a plurality of hydraulic cylinders enabling rotational movement between the parallel frame members, wherein the hydraulic cylinders of the wing sections comprise double-rod cylinders and the hydraulic cylinders of the center section comprises single-rod cylinders.

Rotating toolbar with double rod cylinder

In one embodiment, an implement comprising a center section and a pair of wing sections, each of the sections comprising a pair of parallel frame members pivotably coupled to each other, wherein one of the frame members comprises a toolbar; and a plurality of hydraulic cylinders enabling rotational movement between the parallel frame members, wherein the hydraulic cylinders of the wing sections comprise double rod cylinders and the hydraulic cylinders of the center section comprises single rod cylinders.

A foldable marker mounted to an agricultural implement includes pivotally connected inboard and outboard arms, with the outboard arm supporting a ground marker device. The arms are shiftable between folded and unfolded conditions, with the inboard arm defining a longitudinal axis extending along the length of the inboard arm and a transverse axis orthogonal to the longitudinal axis, with the inboard arm operable to be unfolded so that the transverse axis is substantially aligned with a forward direction in the unfolded condition. A pivot joint defines a pivot axis, with the pivot axis and transverse axis defining a lateral angle of at least twenty degrees and a vertical angle of at least twenty degrees. The outboard arm is in a laterally extended position when the arms are in the unfolded condition and in a laterally retracted position when the arms are in the folded condition.
