In need of a lawnmower. I have a budget of around £170, and a fairly large and wild garden (can't do electric). I've seen the 'Tesco PLM042011 Self Propelled Petrol Lawnmower 173cc' here: http://www.tesco.com/direct/tesco-p...-173cc/213-8675.prd?pageLevel=&skuId=213-8675. The reviews are good, but I'm not so sure.
