  • Patent number: 10645862
    Abstract: A finger wheel for a row cleaner has multiple, spaced, radially extending fingers. Each finger has a concave forward edge with inner and outer sections, and a convex rearward edge with inner and outer sections. The outer sections of the forward and rearward edges converge to a point. A curved connecting section connects the forward edge of one finger to the rearward edge of the next finger.

  • Patent number: 9137939
    Abstract: An electric adjusting apparatus for a row cleaner has a pair of upright posts connected by a pair of parallel linkages, an electric motor with a lead screw and a motor controller. One of the posts mounts on a fertilizing and/or planting apparatus and the row cleaner mounts on the other post. The electric motor moves the parallel linkages to move the row cleaner up and down without tilting. The motor controller controls the electric motor and displays the depth of the row cleaner.

  • Patent number: 8596375
    Abstract: A row cleaner includes a wheel mount, a pair of hubs on the wheel mount and a finger wheel on each hub. The hubs are offset relative to each other in the direction of travel, and angled downwardly and inwardly. The finger wheels are concave and have equally spaced fingers. Each finger has three straight edges at selected angles to provide tapering fingers with a specific shape.

  • Patent number: 5579716
    Abstract: A device for indicating the relative position of a tractor with respect to a crop row or planter mark including a vertically disposed, hollow support post secured to the forward end of the tractor at the centerline thereof. A rotatable shaft is mounted in the support post and has an upper end positioned above the support post and a lower end positioned below the lower end of the support post. A linkage is connected to the lower end of the shaft and has a follower positioned rearwardly thereof which follows the crop row or planter mark. An indicator is secured to the upper end of the shaft for movement therewith. As the tractor drifts laterally with respect to the crop row or planter mark, the indicator moves indicating to the tractor operator that the tractor must be steered back into alignment with the crop row or planter mark.

  • Patent number: 5497836
    Abstract: A row cleaner comprising a pair of ground engageable finger wheels which are angled with respect to each other so they converge forwardly toward the center of their normal path of travel. Each of the finger wheels includes a central disc-shaped portion having a plurality of spaced-apart, elongated fingers extending from the circumference thereof. The longitudinal axis of each of the fingers is disposed at an angle with respect to a radius extending from the center of the disc-shaped portion to the outer end of the finger.
