Good quality mower for a low price - Review by James Hunter
Build Quality
Ease of Use
Value for Money
I bought this to replace a long serving Mountfield that had finally given up the ghost when it blew out after hitting a massive stone. So far I'm not disappointed. For a low cost, basic feature, petrol mower the build quality is pretty good, better than quite a few cheap mowers I've known. It starts first time and the cutting height is easily adjustable. The engine is chunky enough not to cut out frequently when tested in long damp grass. I cut a lot of rough grass on rough ground, as well a decent quality lawn turf, so the most important features of any mower for me are manoeuvrability and the strength of the handle and its attachment to the engine chassis. I've broken off many a handle over the years, particularly using cheap Champion mowers. The Handle on this Mountfield looks to be reasonably strongly attached, the fixing nuts don't loosen quickly and can be easily tightened when they do. Manoeuvrablity is also good - I prefer to sacrifice a bit of cutting width for a lighter mower weight, particularly when cutting over sloping or uneven ground. All in all it's pretty good.
