A planting unit includes a seed meter for singulating and dispensing seed. Opening wheels or discs are included to create an opening in the field, such as a furrow. The unit includes one or more continuous tracks for supporting the row unit as it moves through the field. The tracks can be positioned on opposite sides. The tracks reduce compaction around the created furrow and provide better control of seed depth placement. One or more motors are included to operate the tracks to move the planting unit through a field for planting.

A depth gauge wheel for a row planter. The depth gauge wheel sets the planting depth for the seeds planted by the row planter. The depth gauge wheel sets planting depth by setting the cutting depth of the disk opener of the row planter. The depth gauge wheel also scrapes mud from the disk blade of the disk opener. The depth gauge wheel includes a rim, a tire attached to the rim and a ring attached to the rim. The tire contacts the surface of the ground to set the cutting depth of the disk opener and the ring scrapes mud from the disk blade of the disk opener.

A single disk fertilizer opener assembly for opening a trench in soil includes a frame support and a cutting disk for forming the trench. The cutting disk is coupled to an axle and rotates about the axle as the assembly moves in a working direction. The assembly also includes a first arm pivotally coupled to the frame support and the axle, and a second arm pivotally coupled to the frame support at a location spaced from the first arm. A bracket is coupled to the axle and the second arm, and a scraper is coupled to the bracket and disposed substantially perpendicularly to the working direction.
