The Lawnflite Pro 553HWSP-HST Roller Lawn Mower is a 53cm/21" roller rotary mower that features a top quality 5.5 hp Honda engine. The drive to the roller is shaft rather than belt driven, which is more positive and heavy duty than the belt alternative. The extra features this model gives you over and above a standard 553HRS are, 13% increase in ground speed, heavy duty gearbox, strengthened handle brackets, a deck liner for extra protection and also a front bumper bar which again helps protect the deck from accidental damage. The deck is made of high quality alloy, which because it is rust proof obviously adds to the long life of the machine. The all steel rear roller will give the garden the much sought after 'Traditional British Stripe'. It also has the advantage of making the cutting over lawn edges much easier and the likelihood of damage to those edges is much reduced.
