Abstract
Abstract An agricultural implement effective to remove from the soil implanted crop residue and the like, while at the same time preparing a seed bed for optional concomitant planting operations, the implement having puller wheels that work the soil and converge and grasp the residue below the surface of the soil in uproot the same and feed it into a shredder positioned in receiving relation thereto, the shredder being operative to comminute the residue and having means to selectively collect or distribute it about the field; and a planting assemblage selectively attachable in trailing relation to the shredder and having an orientation with respect to the puller wheels to simultaneously plant a crop in the seed bed prepared by the wheels.

Claim 1
Independent Claim
297 words

Claim 4
Dependent Claim
148 words
An agricultural apparatus for removing plant stalks from the soil and processing the same comprising: a mobile frame; a pair of puller wheels coupled to said frame, said puller wheels converging and cooperatively rotating downwardly to plow up the soil to prepare a seeding bed and simultaneously grasping plant stalks at their roots beneath the soil and extracting them and diverging as they rotate upwardly to release the stalks; doffer means coupled to the frame between said puller wheels for discharging the released stalks therefrom; a chopper coupled to said frame having a crop receiving opening in receiving relationship to said doffer means for receiving the stalks from the puller wheels and shredding the stalks conveyed thereto by said doffer means; and soil preparing and seed planting means coupled to said frame for simultaneously preparing the soil for planting and depositing the seeds in said plowed seeding bed.
Claim 5
Dependent Claim
148 words
An agricultural apparatus for removing plant stalks from the soil and processing the same comprising: a mobile frame; a pair of puller wheels coupled to said frame, said puller wheels converging and cooperatively rotating downwardly to plow up the soil to prepare a seeding bed and simultaneously grasping plant stalks at their roots beneath the soil and extracting them and diverging as they rotate upwardly to release the stalks; doffer means coupled to the frame between said puller wheels for discharging the released stalks therefrom; a chopper coupled to said frame having a crop receiving opening in receiving relationship to said doffer means for receiving the stalks from the puller wheels and shredding the stalks conveyed thereto by said doffer means; and soil preparing and seed planting means coupled to said frame for simultaneously preparing the soil for planting and depositing the seeds in said plowed seeding bed.
Claim 6
