CASE 851 NX vs Mahindra SX Smart 50: Which One to Buy?

Both are backhoe loaders for everyday digging, loading and site work, but they take different paths to get there. The CASE 851 NX runs on more engine power and digs and lifts with more force, backed by a bigger fuel tank for longer working stretches. The Mahindra SX Smart 50 uses a naturally aspirated engine, which is a simpler design that many drivers find easier to maintain, and it is lighter, which helps with transport between sites.

For a contractor who wants stronger digging force and more time between refuelling, the CASE 851 NX handles heavier daily work well. For an owner-operator who wants a lighter machine that is simpler to run and move around, the Mahindra SX Smart 50 keeps things straightforward. Browse the full CASE backhoe loader range and the Mahindra backhoe loader range, or read the backhoe loader buying guide.
