Trimble has introduced a new version of its Trimble® GCS900 Grade Control System with performance improvements for dozers. 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 have the freedom to rotate the dozer blade during operation on steep slopes while maintaining constant grading speeds.

“With the release of the latest version of the system we are taking machine control to a new level,” said Ryan Kunisch, Marketing Director for Trimble Heavy Civil Construction. “GradeMax Plus technology allows contractors to grade between 35 and 40% faster on average, depending on the dozer type and the material being used.”
