Abstract

Through adaptation of and improvement upon secondary, minimum tillage techniques, there is provided a single pass, seedbed method and agricultural machine, utilizing reduction, incorporation, aeration and other procedures, capable of effectively handling all types of adverse field conditions, ground compositions and soil makeup in such manner as to quickly, easily and inexpensively convert all materials and substances therein contained or to be added thereto from a state generally unsuited for seeding and satisfactory plant development to a finished condition wherein any desired seed type may be thereupon planted, sowed or set thereinto without difficulty and with an assurance of good germination and strong, healthy crop growth unimpaired by wind and soil erosion, ineffective moisture retention and other impediments which otherwise normally reduce or destroy profitable harvesting results.

Dependent claims

In a secondary, one trip, minimum tillage, seedbed preparation machine for use during the seeding season,

a carrier;
a plurality of soil penetrating, incorporating slicer disks suspended from the carrier for breaking crusts, reducing crop residue, roots, clods and compaction, and for leveling ridges and other ground surface irregularities;
shielding suspended from the carrier immediately behind the disks for controlling the flow of materials brought up by the disks and leveling the same;
a number of rows of spaced, field cultivator, incorporating blades suspended from the carrier immediately behind the shielding for further reducing compaction and for loosening and aerating the materials sliced by said disks;
rotatable, soil agitating, incorporating reel structure suspended from the carrier immediately behind the blades and adapted to freely roll through said materials for churning, stirring and pulverizing the same to lower the fines to seedbed level and raise the roughage to the top for effecting moisture retention and conservation;
and
a multiplicity of incorporating teeth suspended from the carrier immediately behind the reel structure for harrowing, smoothing, further leveling, settling and firming the materials pulverized by the reel structure to complete the dressing of the seedbed.
