Disc harrow with gang plugging detection

A method for operating a disc harrow implement, wherein the disc harrow implement has at least one gang assembly comprising a plurality of disc gangs, and wherein each disc gang mounts a plurality of disc blades, the method comprising:

• measuring the rotational speed of each of the disc gangs with gang rotation sensors;
• transmitting the rotational speed of each of the disc gangs to a control module;
• comparing the rotational speeds of each of the disc gangs using the control module;
• and
• displaying an alert if one of the disc gangs is rotating at a speed that is a determined amount slower than other of the disc gangs.

An agricultural disc harrow implement comprising:

• a plurality of disc gangs carried by a support bar, wherein each disc gang of the plurality comprises a rotating disc gang shaft supported by the support bar and having a plurality of disc blades, wherein the disc blades are substantially equally spaced along an axis of the disc gang shaft, wherein the disc gangs are coaxially aligned to create a line of substantially equally spaced disc blades;
• and
• a plugging detection system comprising:
• a plurality of gang rotation sensors, each gang rotation sensor configured to detect a rotational speed of one of the plurality of disc gangs;
• and
• a control module configured to compare the rotational speeds of each disc gang of the plurality to the rotational speeds of other disc gangs of the plurality.
