Clearing weeds

The patio that's at back of the house is rather large and about 30 years old and requires lots of weed removal due to the surrounding glen.  We've decided to replace the paving stones with decking, but the chap who's going to do the work won't be free for some months so it's back to removing the weeds that grow between the paving stones.  Luckily we bought a machine that is very light to work with and makes the job a lot easier.
