Cat 120 GC vs Mahindra Roadmaster G80: Which One to Buy?
These two motor graders are built for different scales of work. The Cat 120 GC runs a stronger 171 HP engine, carries a longer 3700 mm blade, and moves faster at up to 48.3 km/hr, so it covers more ground on large projects. The Mahindra Roadmaster G80 runs a smaller 74 HP engine and burns less fuel, at 7 to 8 litres an hour, so it keeps running cost down on smaller jobs.
If you run large road or highway projects and need a wide blade with more power and speed, the Cat 120 GC is the stronger pick. If your projects are smaller and cost-sensitive, and you want lower fuel use over long hours, the Mahindra Roadmaster G80 fits better.
