A system to sense incipient slugging of a rotor by sensing a rotor speed signal, an engine speed signal and a first hydraulic motor speed signal, combining the rotor speed signal and the engine speed signal to provide a second hydraulic motor speed signal, and determining incipient slugging based upon the first and second speed signals, and thereby preventing potential damage to threshing components.

System and method for detecting combine rotor slugging

A system and method for calibrating a cotton module builder having a compactor frame, the system including an electronic controller configured to move the compactor frame to a plurality of positions, to read a compactor frame position sensor or sensors in the first and second positions, and to calibrate the sensor or sensors based on the sensor readings.

Cotton module builder calibration

An agricultural combine has a variable displacement pump connected to four drive motors that drive four wheels. An electronic controller monitors the speed of each wheel and reduces the torque of the motor that drives the wheel when the wheel slips. The controller reduces the torque by reducing the specific displacement of the slipping motor. Once the wheel has ceased slipping, the controller increases the specific displacement of the motor back to its original displacement.

Four-wheel drive combine with slip control

A system for sensing the presence of tailings in a combine includes a tailings sensor configured to generate a signal indicative of a flow rate of tailings and a first microcontroller module coupled to the tailings sensor and configured to receive the signal and filter it by removing transient high excursion noise. The signal may be low-pass filtered and notch filtered to remove other components of noise.

Combine tailings sensor system

An electronic control system includes two speed sensors connected to a microcontroller that is configured to read the sensors and perform the process of determining the gear ratio of a vehicle gearbox. The process includes calculating (several times) which of at least two gear ratios the gearbox is engaged in, then adding up the number of times each of the gear ratios was calculated, and then selecting the gear ratio that was calculated the most times as the true gear ratio.
