I have a set of these “Lawn Care” items for the merry Tiller, Mine has slashing Blades, according to the catalogue they also did a “Hollow Tine” variety, they are weighted , and weigh a tidy amount, but when I tried them on my lawn, they just skipped across the surface, making a few shallow sctatches, not what I was expecting, it must be the technique! does anyone have a copy of the instructions that came with these implements?(usually Alan!) I shall be most oblidged if anyone has a copy . Plonker
