In my experience these things make the moss worse. They do a great job of taking it out but it soon returns, worse than ever. I reckon they kick lots of does up in the air which then settle. I guess it may be ok if you kill the moss first. Does that kill the does? Don't know.
This looks almost identical to the B&D scarifier I wonder if it’s just rebadged
I use one twice a year (first sign of growth/ within last few weeks of summer) i don’t use any moss killer but go over the lawn twice in opposing directions on the first run of the year and very deep , then seed straight away - results are in
Also if anyone could offer any advice on whether this is the best order to treat my lawn in spring 1) apply weed, feed and moss killer 2) scarify a couple of weeks later 3) overseed straight after scarifying id rather overseed straight after scarifying as the seeds can then get right down into the soil, however I’m wondering whether it’s too soon after applying the moss killer - think I read you should leave it 8 weeks before reseeding? Thanks
Good tip! I’ll give that a try in the spring. Can’t believe the wonders that the scarifier does for the lawn, wish I’d bought one years ago
