Abstract:
1. A method for controlling the speed of a self-propelled walk-behind lawn mower having a deck and a handle operatively connected thereto, said method comprising: providing a pair of driven wheels rotatably connected to said deck; providing a transmission assembly operatively connected to said pair of driven wheels and said deck of said lawn mower, said transmission assembly being selectively rotatable between an engaged position and a disengaged position, said transmission assembly generating a selectively variable rotational output to said pair of driven wheels when said transmission assembly is in said engaged position; providing a speed control assembly attachable to said handle of said lawn mower, said speed control assembly comprising: actuating at least one of said pair of levers to cause rotation of said at least one of said pair of levers from said first operative position in which said transmission assembly is located in said disengaged position to said second operative position which rotates said transmission assembly to said engaged position, wherein maintaining actuation of said at least one of said pair of levers in said second operative position by grasping said at least one of said pair of levers causes said transmission to be maintained in said engaged position.
