Mega Grader Blade Continuing on with proven Pearson quality, the Mega Grader Blade range was developed for the larger tractor. Busy farmers want jobs completed to high standards in the shortest amount of time. These large grader blades allow tractors to use all the available horsepower. The Mega grader blades have been designed to suit high horsepower tractors and are ideal for heavy workloads. These blades come standard with three rams and have two options for levelling wheels; one is a wheel centrally mounted to the main body, whilst the other has two wheels that are mounted directly to the back of the blade ends, ideal for when an increased level of finish is required.
