A linear drive assembly configured for use within a power end assembly. The linear drive assembly is configured to interconnect a crankshaft and a pony rod and comprises a crosshead assembly attached to a connecting rod assembly. In one or more embodiments disclosed herein, the connecting rod assembly is configured to attach to opposite sides of the crosshead assembly so that no portion of the connecting rod assembly is disposed within an interior of a crosshead included in the crosshead assembly.

A pulley assembly is provided for mounting on a rotatable shaft of an agricultural harvester and is operable in a high-speed configuration or a low-speed configuration. The pulley assembly comprises a high-speed pulley with a high-speed running surface for receiving a drive belt when the pulley assembly is in the high-speed configuration and a low-speed pulley with a low-speed running surface for receiving a drive belt when the pulley assembly is in the low-speed configuration. The pulley assembly has three sets of teeth extending from surfaces of the two pulleys. In the low-speed configuration, the running surfaces of the low-speed pulley and high-speed pulley are axially aligned and the first set of teeth and the second set of teeth are engaged. In the high-speed configuration, the running surface of the high-speed pulley is exposed for receiving the drive belt.

Robotic systems include an articulated arm having a deformable assembly consisting of having a plurality of bars connected by parallel pivot axes to form at least one deformable structure, the distal end of the deformable assembly supporting a mechanical interface, the system further including two actuators which rotate two of the bars, and a third actuator controlling the translational movement of the deformable assembly in a direction parallel to the pivot axes.
