Claims11
A machine for tilling and planting the surface of a field comprising:
- a frame adapted for movement across a field, said frame adapted to be drawn by a prime mover tractor, the longitudinal attitude of said frame being adjustable from said tractor, whereby the operator of said tractor can independently adjust both the elevation of the front of said frame and the elevation of the rear of said frame;
- a plow unit mounted below the forward portion of said frame, said plow unit comprising a plurality of chisel plows adapted to plow the soil as said frame is moved through the field;
- a reel unit flexibly mounted below said frame, to the rear of said plow unit, said reel unit extending substantially the width of said plow unit, adapted to rotate as said frame is pulled through the field and thereby pulverize the soil, said reel unit being biased downwardly but being limited as to downward movement and as to depth of soil penetration;
- a roller unit flexibly mounted below said frame, to the rear of said reel unit, said roller unit extending substantially the width of said plow unit, and adapted to roll the soil to prepare a seed bed as said frame is pulled through the field;
- and
- a seed planting unit rigidly mounted on the rear of said main frame whereby the seed planting unit is raised from the ground when the rear of the main frame is elevated, said seed planting unit adapted to plant a plurality of rows of seeds as said frame is pulled through the field.
