Bolt-on grade control has been standard practice for two decades, with masts on the blade and cables draped through the cab. Delgrove's MG16 moves the whole system inside the machine: receivers in the roof, inertial units on the circle and drawbar, and no mast to knock off against a kerb.
On finish passes the operator sets a direction and speed and the machine holds the design surface to within six millimetres, cross-slope included. Touching the blade joystick hands control straight back, which Delgrove says matters more for adoption than the accuracy figure.
Fewer passes, same operator
The claimed benefit is pass count rather than speed. In the company's trials on a subdivision road job, finish passes dropped from an average of 3.4 to 2.1, with the largest gains among operators in their first two seasons.
Delgrove is selling the system as standard equipment rather than a dealer-installed option, arguing that integrated calibration is the point. Machines reach dealers in February.
