Bosch AVR 1100 Verticutter
Bought the Verticutter after reading reviews from differing sources and finally took the plunge - great decision, as it does exactly what I wanted; A scarifiier which takes out moss, doesn't denude the lawn, is powerful enough for the job and also easy to use / store.
The only difference, that I found, to other reviewers', was the required height level - I needed level two, which is lower than the majority of reviewers', who said they found level four ( the highest) adequate. All a matter of preference I guess!
Another good feature of the Bosch is that it cuts 'aeration lines' into the grass, consistently - great for aeration and drainage of surface water too.
All in all - worth it so far.
