The HYM46SP is a 139cc 4-stroke self propelled petrol lawn mower from Hyundai, suited for medium to large lawns the HYM46SP has a maximum cutting width of 460mm and is the ideal solution for gardeners whose lawn is on a slope. Simply pull back the handlebar lever to allow the lawn mower to comfortably pull upwards making a easy cutting experience that reduces back and arm stress.

The HYM46SP is the perfect solution for gardeners who require complete control over the type of cut they give their lawn with 4-in-1 functionality providing total freedom.  The 4 cutting options include: Cut & Collect, Cut & Drop, Cut & Mulch and Cut & Side Discharge.  

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 fourth cutting option is side discharge, this is used when cutting long grass or where a fast cut is required and appearance is not a priority

Fitted with a large 1.2 litre fuel tank the HYM46SP boasts impressive cutting power and with low fuel consumption the HYM46SP  is economical to run and ensures you are cutting for longer.

The HYM46SP features a treated steel chassis that protects against rust and corrosion giving you many years of service. For maximum comfort the HYM46SP features a ergonomic soft grip handle.

With a choice of six cutting heights ranging from 25mm to 85mm the HYM46SP puts you in control over the finish to your lawn.  The single cutting height adjustment lever allows effortless selection between the seven cutting heights making it quick and easy to decide.

The massive quick release 70 litre polyester grass catcher compacts the grass cuttings allowing less time emptying and more time mowing, its fabric design optimises air flow which in turn ensures superior collection performance.  The HYM46SP can also be used without the grass collector if you wish to leave the cuttings.

With safety in mind the HYM46SP includes OPC (Operator Presence Control) technology that  ensures the engine will not run if you let go of the handle.  For easy storing the handles can fold down over the lawn mower making storage compact, ideal for the garden shed, garage or transporting within a vehicle.

With low noise levels, vibration and emissions the HYM46SP petrol lawnmower is a all round medium to large sized garden petrol lawnmower that makes quick work of the job in hand.

Weighing 32kg, this is one of the toughest steel deck self propelled petrol lawn mowers on the market.
