ABSTRACT:
A foot pedal is connected to a first link which is also connected to the first arm of a bellcrank. The bellcrank is secured to an input shaft of a hydrostatic transmission. The first link is adapted to reciprocate in opposite directions upon pivoting of the foot pedal in opposite directions. A second link, interconnected between a second arm of the bellcrank and an engine throttle control lever, is adapted to pivot the throttle control lever in the same direction in response to reciprocation of the first link in either direction thereof. Thus, depression of the pedal in either direction will actuate the transmission to place it in its forward or reverse mode of operation whereas the throttle control lever will be actuated in the same direction in response thereto.
