Overview
The Hyundai HYM430SP is an effective, self-propelled, petrol lawn mower that is suitable for use on small to medium sized lawns. It is powered by a 139cc, 4-stroke OHV petrol engine that provides the user with easy starting and low fuel consumption. The HYM430SP has six cutting heights, ranging from 25mm to 75mm, which allows you to tackle a variety of grass lengths and have more control over the finish of your cut. Fitted with a durable steel deck, this product has an easy to remove, spacious 45 litre grass collector which means you will spend less time emptying the bag and more time cutting your lawn. The folding handles also mean you can make the mower more compact which allows for easier storage in your shed or vehicle. The handles also have Operator Presence Control that ensures the engine will not continue running if the user lets go of the handle. The HYM430SP is covered by a Hyundai 3 year platinum warranty.
