A major new feature in Version 4.5 is an enhancement to GradeStar's exclusive automatic side-shift functionality. The operator can now pick any polyline from the plan view window and select it as a horizontal reference or centerline. GradeStar will automatically utilize the selected line and calculate real-time offsets to it. These offsets can be displayed on the screen or--in the case of a motorgrader--used to operate the hydraulic side-shift function.
Other new features include the ability to store hydraulic tuning settings and vehicle data in the vehicle settings files, making it easier to swap the system from machine to machine, and new data screens and views to improve performance.
