On average i'd do about 10 scarifying jobs a summer season,did see the idea on youtube guys using back pack blowers to move the thatch into a pile where i usually rake which is time consuming.
Didn't want to spend heaps on a back pack but would be interested in knowing id anyone has bought this blower.
Usually i'd be looking at a Stihl or Shindy but as it's only for the scarifying and no lawns due to being small yards and it would be a overkill
