Well this is a very useful lawnmower, it collects mulches and importantly has the side dischare facility, so that when either the first cut is too long or for another reason the grass has been allowed to become too long, you can simply use the side discharge to reduce the grass and then proceed as normal. With a 21 cut this mower will easily handle larger areas of lawn. It has an electric start, normally you might think that this is an unnecessary luxury, just something to go wrong. Well all I can say is that. To date the start system has proven robust and reliable........... But do keep the battery charged, NO lithium batteries should ever be left to go flat. Remember these mowers will start on the recoil just the same as any other lawnmower. 21 Cobra Self Propelled / 4 Speed.
