A baler having a frame, a feed system coupled to the frame, a baling chamber for receiving crop from the feed system, and a plunger assembly reciprocally compressing the crop. The baling chamber defines an extrusion axis therethrough. The plunger assembly is at least partially positioned within and movable with respect to the baling chamber. The plunger assembly has at least a first plunger motion aligned with the extrusion axis. The baler also includes a feed system cap having at least a first cap motion aligned with the extrusion axis, the first cap motion being synchronized with the first plunger motion. At least one of the plunger assembly and the feed system cap has a second motion that is not aligned with the extrusion axis.

A baler (10) has a stuffer chute assembly (22) with upper and lower curved walls (44, 46) forming a stuffer chamber (24). A rear portion (54) of the upper wall (44) extends downwardly and forwardly from a baling chamber (12) and a forward portion (50) extends above an inlet opening to the stuffer chamber (24). The upper wall (44) has a plurality of laterally spaced-apart wrappers (52, 56), with adjacent wrappers forming slots (70, 72) extending generally from said crop receiving inlet opening to an outlet opening (48) for cooperation with tines (40) of a feeding mechanism (36). The wrappers (52, 56) are movable relative to the lower wall (46) at a forward end (60) and at a rearward end (66) of the upper wall (44) so as to change a cross-sectional dimension of the stuffer chamber (24). The baler (10) has a forward wall adjusting mechanism (80) for setting a forward end (60) of the upper wall (44) in a predetermined position, and a rear wall adjusting mechanism (110) for setting a rear end (66) of the upper wall (44).

A hay baler includes a compression stage having a first major wall conveying means, a support surface, a first sidewall conveying means, and a second sidewall conveying means, which are arranged to form a compression chamber and each driven at compatible speeds to propel hay toward a downstream end of the compression stage. The first and second major wall conveying means are in spaced relation to each other. The first and second sidewall conveying means are transversely oriented and form first and second side walls of the compression chamber and are angled so that the compression chamber tapers from an initial width at the upstream end to a smaller final width at the downstream end.

A method for determining parameters associated with bale charges formed within agricultural balers includes transmitting microwave signals through a charge of crop material located within a pre-compression chamber of an agricultural baler or into a wall of the pre-compression chamber. Additionally, the method includes determining at least one wave-related property associated with the microwave signals as transmitted through the charge of crop material or into the wall of the pre-compression chamber, and estimating a filling degree of at least a portion of the pre-compression chamber based at least in part on the at least one wave-related property associated with the microwave signals.

A baler including a frame, and a compression system coupled to the frame, where the compression system at least partially defines a compression chamber. The baler also includes a feed pan at least partially defining a pre-compression chamber in operable communication with the compression chamber, where the feed pan includes an inlet defining an inlet area and an outlet defining an outlet area, and where the outlet of the pre-compression chamber is open to the compression chamber of the compression system. The baler also includes at least one actuator coupled to the feed pan, and a controller in operable communication with the at least one actuator, and where the controller is configured to adjust the inlet area and the outlet area independently.

A baler for use with a forming bale having a first bale attribute. The baler including a frame, and a compression system coupled to the frame where the compression system at least partially defines a compression chamber sized to receive at least a portion of the forming bale therein. The baler also includes a feed pan at least partially defining a pre-compression chamber, and where the shape of the pre-compression is adjustable, and where the pre-compression chamber is open to the compression chamber. The baler also includes a sensor configured to output signals representative of the first bale attribute, and a controller in operable communication with the feed pan and the sensor, and where the controller is configured to actively adjust the shape of the pre-compression chamber based at least in part upon the first bale attribute of the forming bale.

An agricultural baler includes a processing conveyance that is positioned between a pickup roll and a main bale chamber for conveying crop material from the pickup roll to the main bale chamber. The processing conveyance includes at least one of a bottom wall and side wall having at least one sieve with a plurality of openings extending through the sieve. The openings are sized and configured for allowing non-crop material to exit from the at least one processing conveyance through the openings.
