Bush Hog® HDRG Series Road Grader

The new Bush Hog® Heavy Duty Road Grader is available in 7-feet and 8-feet operating widths. The HDRG’s heavy duty construction boasts a weight of up to 828-lbs., enabling it to tackle any grading job. The HDRG’s design features all-welded construction, a max rating up to 90 HP, and two offset and angled scraper blades that are vertically adjustable. The vertical blade adjustment system provides the user the ability to adjust the cutting depth to compensate for blade wear and tear.
