Agricultural machine for tilling the soil

Claim 1

A machine for treating the soil comprising, in combination, a main frame; wheels supporting said main frame for translational movement over the ground; an operative assembly, including implements rotatable about a horizontal axis perpendicular to the direction of said translational movement, operable to break and work the soil; means pivotally mounting said operative assembly on said main frame for pivoting about a horizontal axis for elevational displacement of said operative assembly relative to said main frame; motor means supported on said main frame and operatively connected to said rotatable implements to rotate the latter in a direction impelling said machine forwardly; a steering assembly; means pivotally connecting said steering assembly to said main frame; said steering assembly including driving wheels, means for steering said driving wheels, and motor means operatively connected to said driving wheels; whereby said steering means is operable to control the direction and speed of the translational movement of said machine; tank means for carrying fertilizer material, supported by said main frame; means operable to diffuse fertilizer material from said tank means onto the ground in front of said rotatable implements for working into the soil thereby; and interchangeable means carried by said operative assembly rearwardly of said rotatable implements for further treating the soil worked by said rotatable implements; said interchangeable means including means operable to supply seed to the soil.
