As with all of our Hyundai Lawn Mower range, the HYM430SP comes with our Hyundai 3 year home-use warranty* / 1 year commercial warranty* (terms apply) for added peace of mind. I filled it with the required lubricant (which is also easy but needs a little patience for it to settle). The drive to the rear wheels is controlled from the rear-mounted handle control, which provides extra traction to make it easier to mow uneven lawns. Built with safety in mind the HYM430SP comes with OPC (Operator Presence Control) technology, ensuring that the engine will not run if you let go of the handle.
