Abstract: A cleaning system is provided for use with an operating fluid cooling system of an agricultural machine. The cleaning system includes an air plenum adapted to be attached to the cooling system. Fans provided for use in the cooling system exhaust air through the air plenum which has air outlets which direct air to individual mechanisms of the machine to blow away dust and debris from the mechanisms. Thus continuous cleaning of mechanisms during machine operation is enabled without the need for separate blowers, fans, or compressors and the expense and complexity associated therewith.

Abstract: A twine box is provided for an agricultural baler. The twine box permits ready access to twine balls housed therein because all twine balls are located on a single row or tier. The twine balls are not compartmentalized and thus relocation of twine balls within twine ball groups is facilitated. Twine ball separators are employed to secure, locate and separate twine balls when the baler is operating. The twine ball separators may serve to maintain twine balls in a staggered configuration whereby it is possible to house a greater number of twine balls in a given space. The twine ball separators do not interfere with the movement of twine balls within the twine box during reloading of twine. The single row twine box allows the baler operator to access the twine balls from the ground and permits moving of twine balls without the need to cut and retie twine.

Abstract: A knotter arrangement for a large rectangular or square baler includes a plurality of knotter assemblies mounted on a knotter drive shaft. Each knotter assembly includes a knotter drive gear mounted for rotation with, and axial movement along, the knotter drive shaft, and a knotter frame having a sleeve clamped loosely on a hub of an associated knotter drive gear. According to a first embodiment, a pair of jackbolts are screwed into one end of the hub of one knotter drive gear, with the heads of the pair of jackbolts engaging an end of the hub of an adjacent knotter drive gears. In second and third embodiments, for use with knotter drive gears having small diameter hubs, the jackbolts are respectively mounted in either an end face of a spacer mounted on the shaft between adjacent knotter assemblies, or in an end face of a sleeve of the mounting frame that surrounds an elongate section of the drive gear hub.
