The flagship of Hyundai's walk-behind lawnmower range, the Hyundai HYM51SP Lawn Mower is a rugged self-propelled machine has a 5hp four-stroke petrol engine, a choice of seven cutting height settings and a capacious polyester grass collector with robust lid. In common with the smaller HYM46SP model, the new HYM51SP lawn mower offers users the option of four different grass-cutting functions, each one designed to meet specific needs according to user preference, the importance of the grass (in terms of location and appearance) and the length, condition and moisture content of the grass being cut.

You can cut and drop, leaving the clippings spread across the entire cutting width, encouraging rapid break-down if the grass is not too long. Alternatively, you can mulch the cut grass by recycling and reducing the clippings to fine particles beneath the cutter deck, helping promote even faster decomposition. The third and final mode is to discharge the cut grass through a chute attached to the right-hand side of the machine, ideal when wanting to avoid leaving clippings close to buildings or walls or on paths, driveways or paved areas.

Powered by an economical Hyundai four-stroke petrol engine, the HYM51SP has all of the features of its smaller stablemates including convenient single-point cutting height adjustment, a treated steel cutter deck and soft-grip handles with lever controls.

For peace of mind, the Hyundai HYM51SP 4-in-1 lawn mower comes with 2 years warranty.
