Abstract: 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.
