Does anyone know how this lawn rake works? I inherited it from my father who in turn I think got it from his so it could be 1960s or even earlier. I think you may have to take the wheels off but not sure. Many thanks. Writing on label says W Hargreaves Isis Aerake. At the moment the blades would not make contact with the grass. You can loosen a couple of wing nuts and move the handle around in an arc on the yellow body but can see no other adjustment. As you can see from my moss covered lawn it would come in handy!
