FIELD UNIT FOR TESTING TILLAGE WORKING BODIES Russian patent published in 2011 - IPC A01B63/112 G01L5/13 

FIELD: agriculture.

SUBSTANCE: unit includes a rectangular tubular frame with systems of three point hitch and adjustment of depth of soil tillage in the form of support wheels. Working bodies made in the form of a rack with flat hoes and other hoes are mounted rigidly to the frame with brackets. The frame is pivotally connected to the plate and a stop equipped with brackets. Between the plate and the stop there is a dynamometer with a contactless precision potentiometer mounted on it. The dynamometer indicator needle is coaxially connected through the sleeve to the resistance regulator of the potentiometer. Magnetoresistive output of the resistance regulator of the potentiometer is connected through an analog-digital converter with a PC.

EFFECT: design concept enables to expand the technological capabilities of the unit due to increase of speed and precision of processing of test results.
