Why the QuadRod linkage increases accuracy

A short video explaining the difference between our patented QuadRod linkage on a SharpGrade laser grader and a traditional centre pivot blade.

The ability to operate one side of the blade without influencing the position of the opposite side means we can grade much quicker and accurately.

The opposite side (depicted by the arrow) was 100% on grade (the same height as the SharpGrade's wing) but was forced completely off grade by the opposite side. It is a control system's worst nightmare.
