Dynamic resistance generator for square baler

A baler implement, comprising:

• a frame having a central longitudinal axis;
• a first panel partially forming a compression chamber for compressing crop therein;
• a plunger operable to reciprocate within the compression chamber to provide a compressive force to compress crop material in the compression chamber into a flake against a plurality of other flakes of a currently forming bale, and to move the currently forming bale through the compression chamber;
• a first hook positioned on the first panel and operable to engage the currently forming bale inside the compression chamber to resist the compressive force applied by the plunger to increase compression of the crop material within the compression chamber;
• a sensor coupled to a portion of the plunger and operable to measure a characteristic of the portion of the plunger and to transmit a signal indicative of the characteristic of the portion of the plunger;
• and
• a controller configured to change the resistive force from a resistor based on the signal indicative of the characteristic of the portion of the plunger;
• wherein the first panel includes a slot, and wherein the first hook includes a first tooth shaped to penetrate into the currently forming bale through the slot in the first panel;
• wherein the slot includes a front edge and a rear edge opposite to the front edge along the central longitudinal axis, and wherein the first tooth travels between the front edge and the rear edge in a first direction with the currently forming bale while resisting movement of the currently forming bale;
• wherein the first hook includes the resistor, and the resistor is controllable to provide an adjustable resistive force on the currently forming bale, via the first tooth of the first hook, against the compressive force applied by the plunger.
