Zusammenfassung:	A hydrostatic transmission control mechanism includes a hand lever engagable by an operator, and a member to which the hand lever is directly mounted. The member is pivotally mounted to the vehicle and is operatively coupled with the transmission for adjusting the speed of the vehicle as the operator shifts the hand lever. The member includes a generally curved and concave cam surface which interacts with a neutral return cam follower to provide a relatively large effective lever arm extending between the member's pivot axis and the direction of force applied to the cam surface by the cam follower when the member is in positions corresponding to high vehicle velocity, thereby allowing the member to be pivoted back to its neutral position with only a relatively small force.
