Abstract: An agricultural baler includes a main bale chamber, needles, knotters, a triggering system, a knotter lock, a blow-off mechanism, and a monitoring system. The needles are coupled to the main bale chamber and thread twine around a formed bale. The knotters receive the twine from the needles and tie the twine. The triggering system is for activating the needles and the knotters. The knotter lock is a manual lock of the triggering system thereby preventing the needles and the knotters from being triggered. The blow-off mechanism directs a flow of air at the knotters and the needles. The monitoring system has a single sensor that provides signals indicating a normal operation of the knotters, and whether the knotter lock is engaged.

Abstract: 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.
