You can reduce kicking by putting a bag of sand or similar heavy thing on top of it

I picked up the Screwfix tiller for £39 in their Easter sale last week. I had a large part of the garden that I'd dug over a few months before which contains a lot of clay so I ended up having lots of large clods which wouldn't absorb water and break down in the frost. That little tiller made quick work of them. I was amazed how powerful it was for the size, your 'angry pit-bull' analogy is spot on @Emp_Fab ;

  I am very impressed with the little beast, I'm struggling to gardening this year thanks to a broken shoulder that won't heal and this small wonder is making my life a lot easier
