Abstract
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.
Claims11
An agricultural harvester comprising:
- a header and feeder drive system for operating a header and a feeder housing, the header and feeder chive system comprising:
- a forward belt drive arrangement comprising a first pulley, a second pulley, and a forward drive belt arranged about the first pulley and the second pulley;
- an actuator;
- and
- a forward belt drive tensioner connected to the actuator, the forward belt drive tensioner for engaging and disengaging the forward drive belt with the first pulley and the second pulley;
- a reverse belt drive arrangement comprising:
- a reversing motor having a reversing motor pulley selectively drivingly coupled to and decoupled from the header and feeder drive system;
- a reverse drive belt arranged around the reversing motor pulley and the second pulley;
- a reverse belt drive tensioner for engaging and disengaging the reverse drive belt with the reversing motor pulley and the second pulley;
- and
- a linkage system interconnecting the forward belt drive tensioner, the reverse belt drive tensioner, wherein the actuator is configured for operating both the forward belt drive tensioner and the reverse belt drive tensioner with the actuator, the linkage system comprises an engagement arm connected to the actuator, and a tensioner arm and a reverser arm each connected to the engagement arm for being moved by the actuator simultaneously.
