Systems and methods for inhibiting implement-induced engine stall, and turf maintenance vehicles incorporating same

Systems and methods for inhibiting implement-induced stall of a prime mover associated with a turf vehicle. In some embodiments, the vehicle includes an electronic controller (EC) adapted to monitor a speed of the prime mover and detect when the speed falls below a speed threshold. The EC is adapted to automatically disengage a power take-off (PTO) connecting the prime mover to the implement when the speed of the prime mover falls below this speed threshold.

PROTECTING WORK MACHINE FROM DAMAGE DUE TO LOCKED STATE
20200378455 · 2020-12-03 ·

A work machine comprises an engine, a work unit configured to be driven by the engine, a clutch provided between an output shaft of the engine and a power shaft of the work unit, and configured to transmit or cut off power from the output shaft of the engine to the power shaft, a sensor configured to detect an engine speed of the engine; and a control unit configured to control the engine and the clutch based on the engine speed of the engine. The control unit predicts, based on the engine speed of the engine detected by the sensor, whether or not the work unit will become locked by a load, and control the clutch to switch over from a transmission state to a cut-off state upon predicting that the work unit will become locked.

Harvester

A harvester capable of autonomous travel in a field includes: a harvesting unit that harvests a crop from the field; a conveyance device that conveys, toward the rear of a harvester body, a whole culm of the harvested crop harvested by the harvesting unit; a detection sensor that detects a drive speed of the conveyance device; and a clog determining unit that determines a clog of the harvested crop in the conveyance device on the basis of the drive speed. The clog determining unit outputs a vehicle stop command that stops the harvester body when the drive speed becomes lower than a pre-set first threshold during the autonomous travel.

FAILSAFE MODE FOR ARTICULATING HARVESTING HEADER
20200359562 · 2020-11-19 · ·

A control system and method for operating an articulating header of a combine harvester in a failsafe mode. The method includes monitoring the articulating header, alerting a user when a fault condition is detected in the articulating header, and converting the articulating header to a non-articulating header in response to the fault condition so that the combine harvester may be operated in a failsafe mode.

Drive System for a Harvester
20200352100 · 2020-11-12 ·

A harvester comprising: a drive engine connected via a first drive train to ground engagement equipment of the harvester and via a second drive train to crop processing equipment of the harvester; an actuator configured to adjust the transmission ratio of the first drive train to control the propulsion speed of the harvester; and a controller configured to receive setpoint and actual values dependent on the crop throughput of the harvester, the controller configured to calculate an acceleration signal based on the setpoint and actual values, the acceleration signal representing an acceleration of the harvester suitable for minimizing the difference between the setpoint and actual values, and to determine a control signal for controlling the actuator based on the acceleration signal.

Drive train for driving a working unit of a self-propelled harvester

A drive train for driving a working unit of a self-propelled harvester is disclosed. The drive train includes a selectable belt drive with a drive belt, which operationally combines a drive belt pulley and an output belt pulley. The output belt pulley of the belt drive is operationally connected to the working unit via a drive shaft. The drive train comprises a clutch system, combining the functions of a belt clutch and an overload clutch into a single construction unit, with the response characteristic of the overload clutch system being hydraulically adjustable.

Bale forming apparatus and method with a free-wheel clutch
10779475 · 2020-09-22 · ·

A bale forming apparatus including a bale forming device providing a bale forming chamber, a rotatable driving member, a shaft, and a free-wheel clutch provided between the shaft and the rotatable driving member. The shaft drives at least temporarily the rotatable driving member. The free-wheel clutch transfers a rotation of the shaft onto the driving member. The rotated driving member drives at least one part of the bale forming device. The bale forming device forms a bale in the provided bale forming chamber. At least one time the rotatable driving member is rotated with respect to the shaft. The free-wheel clutch enables this rotation of the rotatable driving member.

Method for directing a camera system on agricultural machinery

An agricultural harvesting machine, equipped with a movable unloading apparatus to transport crop material to a container driven in the vicinity, so that the container, seen from the harvester, has a near upper border and a remote upper border, and wherein a 3D camera is provided on the harvester for capturing images in which at least the near border can be seen, to direct the unloading apparatus based on these images. The camera is rotatable mounted around a substantially horizontal axis. The angle of rotation of the rotatable camera can be arranged such that the near border always remains in the field of view of the camera. The unloading apparatus can be controlled such that the processed crop material is deposited in the container at a predetermined distance from the near border.
