Abstract A pair of frame members are interconnected at their opposite ends with the inner ends being connected to the frame of a planter and the outer ends having a pivotal marker arm. One of the frame members is straight while the other frame member includes two portions extending at an angle to the one frame member and interconnected at adjacent ends in spaced relation to the one frame member. A hydraulic cylinder is provided for raising and lowering the frame assembly and is connected to one of a plurality of cross plates in each frame assembly interconnecting elongated side elements. The marker arm includes telescopic portions, one of which is connected to the outer end of the pair of frame members and the other telescopic member extends inwardly beyond the pivotal connection for engagement with a cross element to limit the pivotal movement of the marker arm such that it is maintained substantially parallel to the elongated frame assembly when in its lowered operative position. An upstanding post is provided at the inner end of the frame assembly and includes a resilient bumper for engagement with a cross element on the frame assembly when it is pivoted to its upstanding raised position. A resilient stop is provided on the frame assembly for yieldably limiting pivotal action of the marker arm toward the frame assembly when the frame assembly is in its raised position. An upstanding arcuate element is provided on the marker arm and is connected to a chain extending to the upstanding post such that when the frame assembly is lowered the marker arm is extended and when the frame assembly is raised the marker arm is allowed to pivot downwardly against the yieldable stop element on the frame assembly. A depth-control band is provided on the disk element on the outer end of the marker arm.

A planter marker comprising, an elongated frame assembly having a pair of frame members interconnected at their inner and outer ends with said inner ends being adapted to be pivotally connected to the frame of a planter and the outer ends including a pivotal marker arm, one of said pair of frame members being straight along its substantial length and said other frame member having two portions with their outer ends connected to the opposite ends of said one frame member and said two portions extending at an angle to said one frame member and interconnected at their inner ends in lateral spaced relation to the inner end of said one frame member, each of said pair of frame members including spaced apart elongated side elements interconnected by a plurality of cross elements, a downwardly extending planter mounting bracket being provided on the inner ends of said pair of frame members and a hydraulic power cylinder being connected to the other of said frame members at one end thereof and the other end being connected to said mounting bracket remotely of said pair of frame members to provide for a lever arm for pivotal movement of said frame assembly, an upstanding post being provided on said mounting bracket and including a yieldable bumper in the path of said frame assembly when pivoted to an up position thereby limiting the up travel of said frame assembly, said pivotal marker arm being connected to the outer end of said pair of frame members at a point intermediate the ends thereof and one of said cross elements being positioned in the path of pivotal movement of said inner end of said marker arm to maintain said marker arm substantially parallel to said frame assembly when said frame assembly is in an operative lowered position, said marker arm including a pair of telescopic members and one of said telescopic members being secured to the outer end of said pair of frames and the other telescopic member may be telescopically movable relative to said one telescopic Member, a yieldable cushion element being provided between said pair of frame members and said marker arm in the path of said market arm as it pivots towards said pair of frame members when said pair of frame members is in a vertical raised position, said marker arm including a 180* arcuate guide member and said marker arm bisects radially said guide member, a chain extends from the upper end of said guide member to said upstanding post above the pivotal connection of said pair of frame members to said planter frame and the length of said chain is such that upon said pair of frame members pivoting to said lowered operative position said chain becomes taut and said marker arm is pivoted up to a position substantially parallel with said pair of frame members and when said pair of frame members is raised said chain becomes loose allowing said marker arm to pivot towards said pair of frame members.
