Abstract: A control arrangement for a lawn and garden vehicle having a manually movable member provided for controlling the speed of operation of the tractor and a speed setting arrangement for permitting the operator to manually set a speed control at a minimum constant speed while also permitting the operator to move the manually movable member to temporarily increase the speed of the vehicle. The speed setting arrangement is connected to the lawn tractor brake to cause disengagement of the speed setting apparatus when the brake is applied.

Abstract: A control assembly for use in controlling the operation of a hydrostatic transmission of a lawn and garden vehicle. The control assembly is selectively adjustable such that it can be set precisely at the neutral position of the transmission. The control assembly also provides means for causing the transmission to positively return to its neutral position after operation in either the forward or reverse driving modes.

Abstract: A two stroke cycle internal combustion engine having a closed crankcase adapted to receive a air-fuel mixture and a cylinder extending from said crankcase,a piston reciprocally movable in said cylinder which alternately produces a low pressure condition in said crankcase as it approaches top dead center and a high pressure condition in said cylinder as it approaches bottom dead center,a fuel reservoir for supplying liquid fuel to the air fuel mixture in said crankcase, a bypass passage connecting said crankcase to said cylinder,and a conduit connecting said crankcase to the fuel reservoir for pumping fuel accumulated in said crankcase during starting into said reservoir, and a unidirectional flow control device in said conduit for preventing return flow from said reservoir to said crankcase.
