An improved control linkage for a lawn mower having a mower deck selectively moveable upwards and downwards in respect to a frame in a range of operative positions and further moveable substantially parallel to the ground to a non-operative position, the control linkage comprising a lockout bolt, said lockout bolt having two ends, one means to connect one end of said lockout bolt to the frame, another means to connect the other end of said lockout bolt to the mower deck, one of said one means or said another means including a lost motion connection, said lost motion connection allowing said lockout bolt to engage between the frame and mower deck when the distance between the frame and mower deck is equal to the operative length of said lockout bolt, said one end of said lockout bolt being displaced from said other end of said lockout bolt in a direction opposite to the movement of the mower deck substantially parallel to the ground to a non-operative position of the mower deck, and said operative length of said lockout bolt being such that the mower deck can be moved freely through its range of operative positions without compromise to the operability of the mower deck while the motion of the mower deck upwards of the range of operative positions connects both of said ends of said lockout bolt to the frame and deck causing said lockout bolt to force the mower deck substantially parallel to the ground to its non-operative position.
