Product details and specs
The 1643H-SD Twin is a fantastic side discharge lawn tractor. Powered by a formidable Stiga ST550 585cc twin cylinder engine that is powerful to cut through the toughest of lawns. With no bulky collection basket present, it is also highly manoeuvrable.
The 108cm twin bladed cutting deck makes light work of large areas and the hydrostatic transmission, akin to the automatic transmission in cars, is slick. There are seven cutting heights all selected using one lever and a simple flick of a switch engages the blades.
As a dedicated side-discharge machine this mower is excellent when grass growth is fast, however, you could choose to mulch the clippings using a mulching plug/plate (available as an optional extra) that is simple to fit. When mulching, the clippings are finely cut and blown back down onto the lawn to decompose and return valuable nutrients to the soil.
Cleaning after use couldn’t be easier just connect your hose to the deck nozzle, turn on the water and engage the blades and you will quickly have a clean deck and blades ready for next time.
With a wide range of towed accessories available, the Tow Hitch available as an optional extra makes the 1643H-SD extremely versatile in all seasons.
And of course, the 1643H-SD Twin comes with a reassuring five-year extended warranty. (T&Cs apply)
