GCS900 version 12.7 features GradeMax Plus, new technology that increases the overall performance of dozers by allowing the operator to grade faster and more consistently with tighter accuracy. The system uses the Trimble GS420 Inertial Measurement Unit (IMU) sensor to detect the current rate of acceleration and changes in orientation. Trimble has also increased the rate at which the GCS900 system drives the valves on the dozer for smoother, more consistent control and rapid recovery of the dozer blade so operators can grade higher quality surfaces at even faster speeds. With GradeMax Plus, operators can grade a wider range of complex surfaces without constraints.
For example, operators are free to rotate the dozer blade during work on steep slopes while maintaining constant grading speeds. Ryan Kunisch, marketing director for Trimble, said: “GradeMax Plus technology allows contractors to grade between 35 and 40% faster on average, depending on the dozer type and the material being used.”
