An Agricultural baler having a flywheel that is driven via a drive shaft. The flywheel is connected to a pressing component of the baler via a central shaft, wherein the flywheel is mounted over the central shaft via bearings. Further mounted on the central shaft is a shear pin flange which is connected via a shear pin to the flywheel for the purpose of transmitting a rotation movement of the flywheel to the central shaft, wherein the flywheel is held over the central shaft via first fixing component and wherein the shear pin flange is connected to the central shaft via second fixing component.

A combine side-shaking control system includes a sieve for separating crop material from other materials and a movable side-shaking mechanism coupled to the sieve and configured to move the sieve in a side-to-side motion. The control system also includes also includes first and second grain loss sensors configured to sense amounts of grain loss from separate portions of the sieve. The control system further includes a controller configured to: (i) receive a first grain loss value corresponding to the sensed first amount of grain loss and a second grain loss value corresponding to the sensed second amount of grain loss; and (ii) cause the side-shaking mechanism to control movement of the sieve in the side-to-side motion based on at least one of the received first grain loss value and the received second grain loss value.

A material processing device has a rotor coupled to a rotatable shaft, and a rotor control system. The rotor control system comprises a rotor control mechanism with a first engagement member that is engagable with a second engagement member coupled to the shaft. The rotor control mechanism is operable into and out of an engaged state in which the first and second engagement members are engaged with one another. In the engaged state, the rotor control mechanism is operable in a locking mode in which the first engagement member is fixed in position to prevent rotation of the shaft, or in a rotation mode in which the first engagement member is movable to rotate the shaft. The material processing device may be a crusher, a shredder or a milling machine.

An agricultural machine comprising an input shaft connectable to the power take off shaft of a tractor; a flywheel connected to the input shaft; workings driven by the input shaft; an access panel openable to provide access to the workings of the machine; an access panel handle having a first position for opening and a second position for closing the access panel; and a brake for arresting rotating of the flywheel with a brake handle with a first position for braking the flywheel and a second position for releasing the flywheel; the access panel handle and the brake handle are arranged with respect to each other such that the access panel handle can only be placed in its first opening position when the brake is in first braking position.
