You got it Trev they are so totally undersized it is obvious to see why they would not be capable of a lot of work for what is supposed to be a decent sized cutting machine. Easy to see why they fall to bits, but I guess it has a lot to do with the people who buy this sort of machine. I assume they were a cheap machine for the cutting size and as we know most people do minimal maintenance, use it till it breaks, take it to a mower shop, find out how much it is going to cost and they then realize it is going to cost more to repair than it is to buy another one. The little Greenie I got for my mate for $180 had just had $1100 in repairs spent on it before the owner gave up and went out and bought a new one. I still spent another $300 in parts on it and I have just put a new motor on it. Now it is a good machine, but the labour spent on it has been massive
