COMBINED TILLAGE TOOL Russian patent published in 2007 - IPC A01B49/02 A01B67/00 

FIELD: agricultural engineering, in particular, means used for basic soil tillage, cultivation and application of fertilizers and/or ameliorants.

SUBSTANCE: combined tillage tool has pulling means comprising turbosupercharger engine, gear box, hydraulic system, automatic engine load measuring unit, first, second and third actuating devices, controller, extrapolator, optimum definer, setter unit, and tillage command former. Output of load measuring unit is connected to first input of extrapolator, whose first output is connected to first input of controller and second output is connected to first input of optimum definer. Output of setter unit is connected to second input of controller, to third input of which controller output of optimum definer is connected. Tillage command former is connected to second control inputs of extrapolator, optimum definer and control input of setter unit. Output of optimum definer is connected to input of second comparator whose output is connected through third actuating device by means of tie-rod to control rack adapted for controlling of fuel feeding process.

EFFECT: increased precision in defining of optimum operation modes for engine and efficiency of soil tillage processes.
