I have a large hilly bank (could not worl a lawn-mower) that I need to hit with a strimmer. I used to borrow one (petrol), but it had died so I need to buy one. I am based in Shankill, and was wondering is someone could recommend a) a place to buy one and b) what one to get. The area involved would be equivalent to a large garden and the vegetation is heavy grass. An electric one would not do the job, unless it was much beefier than any one that I have ever seen.
