Abstract: Methods and apparatus are disclosed for controlling machine configurations. An example method includes deter mining a desired trajectory of an auxiliary machine based at least in part on a desired work path or an alignment of a host machine and the auxiliary machine; determining a first actual trajectory of the auxiliary machine based on i) determining a first distance between a first side of the auxiliary machine and the host machine and ii) determining a second distance between a second side of the auxiliary machine and the host machine, the first side is opposite the second side; comparing the desired trajectory of the auxiliary machine to the first actual trajectory of the auxiliary machine; and when the first actual trajectory does not satisfy a threshold distance of the desired trajectory, selecting a trajectory-assist mode to steer the auxiliary machine toward the desired trajectory.

Abstract: Methods and apparatus are disclosed for controlling machine configurations. An example method disclosed herein includes identifying a machine configuration, the machine configuration comprising a host machine connected to an auxiliary machine; determining a desired trajectory based on at least one of the host machine turning, a desired work path, or an alignment of the host machine and the auxiliary machine; and controlling steering of the auxiliary machine based on a desired trajectory of the host machine.

Abstract: A resonator attenuates sound waves at first and second frequencies. The resonator includes a first tube, and a second tube received within the first tube. Both tubes have an open end and a closed end. The first tube has an axial length which is longer than the axial length of the second tube. The first tube attenuates sound waves at the first frequency and the second tube attenuates sound waves at the second frequency. The second tube has an outer wall which engages an inner wall of the first tube. The open end of the second tube is surrounded by the open end of the first tube. The open end of the first tube is attached to an engine air intake conduit. The conduit communicates air from a charge air cooler to an engine intake manifold.

Abstract: A drawbar clevis assembly includes a drawbar with a greater offset between the upper inboard member and the lower outboard member. The clevis assembly also includes a strap which is mounted to the drawbar and which has an opening in a mid portion. The strap is slid over the drawbar so that the opening receives a portion of the drawbar and so that the inner portion of the strap is attached to an underside of the inboard portion of the drawbar.

Abstract: A vehicle drawbar hammer strap assembly may be coupled to an implement tongue with a drawbar pin. A cross pin with a lever arm is operable to releasably hold the drawbar pin. A trigger is engagable with the tongue and the cross pin, and is pivotal from a latched position wherein it engages the cross pin and holds the cross pin in its locked position to an unlatched position wherein it is spaced apart from the cross pin. The tongue engages the trigger and pivot the trigger in an over-center manner from its latched to its unlatched position. The trigger includes a latch member attached to a wire form part which is pivotally coupled to the hammer strap. The latch member is engagable with the lever arm and with an end of the tongue.

Abstract: A drawbar hammer strap assembly design achieves a low profile, and prevents rotation of the drawbar and of the cross pin. The drawbar hammer strap assembly includes a drawbar, a hammer strap member attached to the drawbar, a drawbar pin mountable to drawbar and hammer strap member and a cross pin rotatably mounted in the hammer strap for releasably holding the drawbar pin in its mounted position. The hammer strap has a pair of detent recesses formed in the sides thereof. The drawbar hammer strap assembly also includes a handle member which is pivotally coupled to an upper end of the drawbar pin. The handle member is pivotal to an unlatched position wherein it is spaced apart from the detent recess, and to a latched position wherein it is releasably received in the detent recess. The handle member is engagable with a lever arm of the cross pin to hold the cross pin in its locked position when the handle member is in its latched position.
