| Abstract: |
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:
1. A power-driven ride-on steerable paint striper machine comprising in combination: a motorized and ridable two-wheeled push tractor unit, a wheeled steerable paint striping unit, a pivotable coupling joint joining said units into an articulated motor driven tractor-striper assembly with said coupling joint positioned with the wheeled steerable paint striping unit in front and said motorized push tractor unit in the rear for moving the paint striper under control of a driver riding on the tractor unit and steering means comprising an equal torque drive mechanism for the two tractor wheels which steers the paint striping unit for the painting of a straight line without manual steering force on the paint striping unit.
