Improved paint striper control, speed and quality is achieved by articulating a motor driven push tractor unit to a steerable walk behind paint striping unit. In a preferred embodiment, a two wheeled rear push tractor unit supporting a drive motor and driver's seat is coupled through a quick release ball-socket pivot joint behind a three wheeled handlebar steered push-to-paint manual striping unit. The articulation joint with help of a hydrostatic trans-axle transmission in the tractor unit produces a sharp turning eighty degree radius. Also the transmission unit functions to drive the assembly in straight lines. The user controls steering to deviate from a straight line at the handlebar grips in substantially the same manner as if walking behind the paint striper. Thus the user rides quickly along the striping path with a good view at the paint spray jets to monitor performance and achieve higher output volume and quality.

[ I claim:] [11.] The combination of a motorized ridable push tractor having two drive wheels, said tractor being articulated to push a walk-behind steerable paint striping unit, characterized by means in said tractor unit for providing equal drive torque to said two drive wheels thereby steering said paint striping unit for painting of a straight line without the exertion of manual steering control.
