A shaft assembly. The shaft assembly includes a joint assembly having a first joint member, a second joint member and one or more third joint members drivingly connecting said first and second joint members. At least a portion of a first shaft is drivingly connected to the second joint member. Circumferentially extending from at least a portion of an outer surface of a second end portion of the first shaft is a first and second increased diameter portion having a wall portion that connects the first increased diameter portion to the second increased diameter portion. Drivingly connected to the second increased diameter portion of the first shaft is a second shaft. During a crash condition, an amount of force is applied to the wall portion until it fractures and at least a portion of the first shaft and/or the joint assembly translates into a hollow portion of the second shaft.

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.

A vehicle shaft assembly (500). The shaft assembly includes a coupling assembly having a first (506), a second (508) and a third (510) joint member. A substantially cylindrical body portion of the second joint member is drivingly connected to a first shaft (560) having an increased diameter portion. The increased diameter portion of the first shaft has a retaining member groove (604) circumferentially extending along at least a portion of an outer surface of the increased diameter portion. At least a portion of the increased diameter portion of the first shaft is drivingly connected to a crash collapse adapter (608) having a crash collapse feature circumferentially extending along an inner surface of the crash collapse adapter. A second shaft (640) is integrally connected to at least a portion of an outer surface of the crash collapse adapter (608). At least a portion of a retaining member is disposed within the retaining member groove and the crash collapse feature.
