ABSTRACT:
A grain drill is disclosed having a folding frame for parallel operation and a parallel link system that controls the tension to earth openers in order to produce relatively constant downward pressure for the openers. The grain drill includes a rotating tool bar for facilitating the adjustment of downward pressure to the openers, controlling the ground cutting depth of the openers and raising the tools to obtain the ground clearance needed for road transport. The drill has disc openers with axially collocated discs having different outer diameters and a narrow angle between the opener discs producing a "V" shaped groove for seeding. The grain drill has a common horizontal center to support seed boxes, fixed dual wheels and a hitch for connection to a pulling vehicle.
