I managed to get a RotaRola which being a WA boy I was very happy about. As has been documented on the site previously it is designed and made by Ings engineering in Perth. What was of particular interest to me is the edger attachment. This is the second of this style I have seen, the other is fitted to one of my Turners. I'm thinking these attachments were available as optional extras but have no proof of this. Had a good chat with the current owners son of Ings and he confirmed the edger attachment was factory fitted to some early models so I guess this unit would be around 63/4 as this mower model including the engine ( Kirby/Lauson ) looks identical to the image Jack has posted in the past. It appears to be a very original unmodified example of this machine with a beautifully made reproduction catcher, the seller had this made some time ago.
