Abstract
An improved gear shift mechanism for an auger gear drive which uses a hydraulic cylinder or other linear force means to push on one end of a rocker arm. This moves the rocker arm and the gear train between a first gear set and a second gear set. A biasing means is applied directly to the rocker arm by a spring or other device. The design eliminates adjustable linkages and the need adjustments in the field and allows for use of a simpler hydraulic cylinder than found in the prior art.
