Electronic sensor assembly for monitoring smoothing tools of a harrow

An agricultural tillage implement, comprising:

• a main implement frame supporting a set of ground-engaging tillage tools for tilling soil during a tilling session for seedbed preparation;
• a soil finish system supported by the main implement frame for smoothing the soil tilled by the ground-engaging tillage tools, the soil finish system including:
• a harrow supported in a trailing position with respect to the main implement frame, wherein the harrow includes a harrow frame with multiple bars arranged generally transversely with respect to a travel direction of the agricultural tillage implement, wherein the multiple bars support a first set of smoothing tools fro smoothing the soil tilled by the ground-engaging tillage tools;
• a hydraulic system configured to define an angle of the first set of smoothing tools for the tilling session;
• a sensor assembly in communication with the hydraulic system, wherein the sensor assembly is configured to generate an electrical signal corresponding to the angle of the first set of smoothing tools;
• and
• a slide bar in communication with the hydraulic system, the slide bar being operable to define the angle of the first set of smoothing tools by stopping a rotation of the multiple bars upon actuation by the hydraulic system.

• and
• a soil finish system supported by the main implement frame for smoothing the soil tilled by the ground-engaging tillage tools, the soil finish system including:
• (a) a harrow supported in a trailing position with respect to the main implement frame, wherein the harrow includes a harrow frame with multiple bars arranged generally transversely with respect to a travel direction of the agricultural tillage implement with the multiple bars of the harrow flame including a front bar arranged toward a front end of the harrow, a back bar arranged toward a back end of the harrow, and an intermediate bar arranged between the front and back bars of the harrow, wherein the harrow includes a first set of smoothing tools supported by the front, back, and intermediate bars of the harrow frame for smoothing the soil tilled by the ground-engaging tillage tools;
• (b) a hydraulic system configured to define an angle of the first set of smoothing tools for the tilling session;
• (c) a sensor assembly supported by the harrow frame and in communication with the hydraulic system, the sensor assembly including a pivoting arm movable in conjunction with the movement of the first set of smoothing tools and is configured to generate an electrical signal corresponding to the angle of the first set of smoothing tools;
• and
• (d) a finishing tool supported in a trailing position with respect to the harrow with the finishing tool including a second set of smoothing tools for smoothing the soil tilled by the ground-engaging tillage tools.
