Cat 120 GC vs Mahindra G75 Smart: Which One to Buy?
These two motor graders serve very different jobs. The Cat 120 GC is a bigger, more powerful grader built for large road projects and highway work, where a wide blade and steady speed cover long stretches fast. The Mahindra G75 Smart is smaller and lighter, with power steering that makes it easy to turn in tight village roads and small sites.
For a big infrastructure company running highway or airport work, the Cat's size and power suit long shifts on open ground. For a small contractor doing rural roads, farm paths or municipal work, the Mahindra is lighter to move between sites, simpler to drive, and backed by Mahindra's wide dealer reach across small towns in India.
