ABSTRACT A self-propelled street sweeping machine or sweeper which includes a main frame, A dirt hopper and a main broom are mounted on the frame along with a conveyor. The conveyor is positionable relative to the frame for receiving sweepings from the main broom and for discharging the sweepings into the dirt hopper. Means are provided on the sweeper for enabling the main broom and the conveyor to move selectively of a transport position to a sweeping position and vice versa. The frame is supported by front and rear axles carried on wheels and spring means are provided between the rear axle and the main frame to enable an easier ride while the sweeper is operated in the transport position. Lockout Means has been provided between the frame and spring means, and it is only effective to lock out the spring means preventing relative movement between the frame and the rear axle when the conveyor is placed in the sweeping position to receive sweepings but ineffective to inhibit operation of said spring means when the conveyor is moved into the transport position.
