The Kaaz mowers (inc lawnflite pro, cobra,sarp etc, as the are all built by Kaaz) are in my opinion the best quality mower available on the UK market, but as has been said, they are heavy and come in well over the £1000 so don't suit all.
However, for those wanting to save a couple of hundred there is now a new kid on the block. Mountfield have now introduced a serious roller mower for the first time in the last 15 years. Utilising their new 'twinclip' chassis this mower has a heavy duty galvanised steel deck giving excellent resistance to impact damage, but as steel decks are always weak around the stress points of axle and handlebar mounting these mowers have tough aluminium inserts front and back carrying the axles and the handlebars. The handlebars are easily foldable and the pivots are about the toughest I have ever seen, without the flex that many have.
Roller mowers are notorious for transmission failure so to combat this Mountfield have fitted an extremely tough cone clutch box coupled with a two pulley variator, so no idlers to sieze. This drives a large diameter fluted steel roller so traction will not be a problem.
Power is supplied by a 190cc Honda GCV190 motor
The 'twinclip' blade has 4 cutting edges so each blade of grass is cut twice, which means shorter bits being blown into the box, resulting in a better fill.
I saw, and used this mower at a dealer conference last week and was very impressed. Its not at present aimed at the Pro market (although carrying a 5yr domestic warranty and a 90 day commercial warranty) but the general feeling is that at the selling price of around £850 this mower, the SP555R V is going to take some beating. I will certainly be including it in my range and adding it to the website.
It will be worth a visit to your local Stiga Mountfield dealer.
