ABSTRACT:
An implement such as a tractor-propelled, multi-row planter having row markers hingedly mounted on opposite sides is provided with an automatically operating hydraulic sequencing valve for alternately actuating the markers. The sequencing valve is adapted to be readily connected with the hydraulic system of the tractor used to raise and lower the implement. If desired the hydraulic circuit may be arranged so that the sequencing valve is automatically actuated or sequenced when the implement is raised and lowered whereby the oppositely mounted markers are alternately raised and lowered automatically with the raising and lowering of the implement itself.
