Role

Trailed grader for the rehabilitation of roads, earthworks, it provides the same quality of work as a self propelled grader.

Operation
  • Hitched to the trailer hitch of the tractor (about 80cm from the ground), it provides an excellent weight transfer to the tractor.
  • A concrete ballast weight ensures penetration of the blade into the soil.
  • A single-acting cylinder, acting on the boom, adjusts the working depth.
  • The rear axle (or double axle on TP model) is pivotally mounted; a double acting cylinder tilts the frame and the blade left or right, thus achieving lateral slopes.
  • The blade can be optionally equipped with an hydraulic orientation and a hydraulic lock.
  • On TP models, four rear wheels are mounted on an axle beam, improving the working accuracy of the blade.
Advantages
  • Real grader with adjustable blade orientation, tilt and depth.
  • The wheels of the grader run on leveled ground behind the blade, providing an excellent working precision.
  • The wheels of the grader Perrein are not driven, they cannot skate (like on a self propelled grader), control blade depth is optimum.
  • The position of the rear wheels of the tractor, the grader blade and the wheels of the grader is the same position as the position of the front wheels, the blade and the rear wheels of a self propelled grader. It ensures the same quality of work.
  • Possible slippage of the wheels of the tractor (or crushing of tires) has a minimal effect on the variations of the depth of the blade. According to their position relative to the blade, a 5cm rut (or crushing of the tire) results in only 1cm in the working depth of the blade.
