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.

Pulley assembly for an agricultural harvester

An agricultural harvester has a header and feeder drive system including a forward belt drive arrangement and a reverse belt drive arrangement. The forward belt drive arrangement includes a forward drive belt and a forward belt drive tensioner operated by an actuator. The reverse belt drive arrangement includes a reversing motor and a reverse drive belt selectively engaged with the feeder drive system by operation of the same actuator.

Integrated reversing system with belt engagement

A tension roller assembly includes a tension roller, a pivotable support arm, a tension arm, a compression spring, a rod, first and second spring stops, a mounting plate, and an overcenter assembly connected to an end of the tension arm. The overcenter assembly connects the tension arm to the mounting plate. The overcenter assembly is configured to make a pivoting movement over a pivot trajectory between engaged and disengaged positions. The overcenter assembly further has a center position located between the engaged and disengaged positions. The pivot trajectory between the center position and the disengaged position is divided into a tensioned section in which the end stop does not engage the stop surface and the spring exerts a force on the overcenter assembly, and a free-moving section in which the end stop engages the stop surface and the spring does not exert any force on the overcenter assembly.
