The Graco 17U804 LineLazer V 3900 HP Automatic Series is a high-performance gas-powered airless line striper built for contractors who need both automation and flexibility in the field. Featuring a hybrid configuration with one automatic gun and one manual gun, this unit allows operators to switch between push-button striping and manual control depending on the application.
Equipped with the LazerGuide 2000 laser-guided layout system, this striper enables precise, one-person layout work without the need for string lines, tape measures, or chalk. Combined with Auto-Layout II, SmartControl, and Graco’s J-Log system, the 3900 HP Automatic delivers faster job completion, consistent line quality, and verifiable proof-of-work data.
Powered by a Honda GX120 engine and built with the Endurance Chromex pump, this unit is designed for reliable, everyday performance across parking lots, commercial properties, and re-striping projects.
This model is ideal for contractors who want the benefits of automation while maintaining manual control capability for detail work and custom layouts.
