A plowing implement is disclosed for following and filling wheel tracks created, for example, behind a pair of sprinkler wheel tires, particularly arrangements in which each tire repeatedly traverses the same fixed path. When the track created by the tire is filled with earth by the device of the present invention, plowing or harvesting equipment can cross the path travelled by the wheels without the inconvenience of traversing rough or uneven ruts or tracks which would otherwise be the result.

In combination with ground wheel means subject to forming a depressed track in the earth over which the wheel means rolls, a plowing implement for levelling the track produced in the earth by the wheel means moving in a forward direction, comprising plowing means for followingly throwing earth adjacent the track into the track, mounting means for adjustably mounting the plowing means, and a pulling assembly connecting the mounting means to the wheel means, wherein the mounting means is adapted for swiveling in response to change in direction of the wheel means, whereby the plowing implement is protected against damage during reverse movement of the wheel means without substantially impeding said reverse movement, said pulling assembly including follower means to permit the plowing means to match the contour of the earth, said plowing means comprising a pair of disks mounted opposably the mounting means, the disks when in use describing a path of travel over the earth immediately adjacent the track and forming an acute angle with respect to their direction of travel, whereby the disks travel over the earth adjacent the track and throw said adjacent earth into the track, said pulling assembly comprises said follower means, together with a pull bar fixedly mounted on the wheel means and a channel bar to which the mounting means is attached, the channel bar being connected by the follower means to the pull bar, the follower means further comprising a follower rod attached to the pull bar and terminating directly behind the wheel means and when in use also terminating above the tracks, the follower means further including a swivel collar to which the channel bar is rigidly attached, the swivel collar being freely rotatable on the follower rod to permit the channel bar mounted thereby to pivotably adjust the elevation of the mounting means in response to the contour of the earth, the follower means further comprising adjustable locking collars to prevent longitudinal sliding of the swivel collar on the pull bar and to center the disks upon said adjacent earth.
