Abstract
A system for operating a work vehicle may include an engine and a transmission coupled to the engine. The transmission may include a planetary gear unit configured to be selectively coupled to the engine by engaging one of two directional clutches of the transmission. The transmission may also include a hydrostatic drive unit having an input configured to be rotationally coupled to the engine and an output configured to be rotationally coupled to the planetary gear unit. Moreover, the transmission may include a bypass shaft assembly having a bypass shaft configured to be selectively coupled between the output of the hydrostatic drive unit and a given range clutch of the transmission via a bypass clutch. In addition, the system may include a controller configured to operate the transmission in a hydrostatic bypass mode by disengaging the directional clutches and by engaging the bypass clutch and the given range clutch.
