Countax c600h?

Like Mr Hawkins, I have the same problem with mine....although it does engage longer than his, but you can't always tell by the sound of the engine that the blades have stopped, it's only when you turn to do the next row that you realise. Mine is being collected by dealer tomorrow, so when I get the reason I will post it on here. Another annoying feature is the bag emptying system...I feel the lift could be designed better, because you cannot empty the bag in one spot...you have to drag the machine forward which means you need a lot of space.
