Howdy, I'd like to introduce you to my impulse purchase of an Ottcraft edge-o-matic (classic American name) lawn Edger.
When bought off ebay pictures showed a small hole in the solid rubber tyre, small repair no big deal, when arrived three weeks later it turned out to be an enormous hole around fragments of brittle plastic laying shattered in the box. Ah, could be interesting finding a tyre to fit. So bought a roughly sized plastic castor with solid rubber tyre, went to work with the Dremel, gave it a lick if paint and whalla,
Heres the quirky little edger that isn't any good at edging and by far the most expensive mowery type thing I've bought. Good fun though.
