The RoadMaster G75 is created to offer an affordable, un-compromised and mechanized grading solution for small & medium roads. The RoadMaster G75 is an ideal grading machine for spreading and grading of earthwork, GSB(aggregates/crushed stone) and WBM/WMM(fine aggregate mix with water) in different types of roadwork across the nation in addition to being used for railway and ground levelling operations across sectors. The G75 is designed to provide optimal output at affordable cost with its simple yet rugged design. The RoadMaster G75 comes with GPRS based remote monitoring system DigiSense that keeps a track of your machine with the touch of a finger.
