So, day before yesterday I fetched out the mower for the first time after winter and once again laid the orange cable out of reach of the cutter. What I could do with, I thought, was a helper (person) to pay out just the right amount of cable as I perambulate around the lawn with the thing. A robot would also do the trick, but for the money I could employ a gardener.
That's when I saw the washing line, as if for the first time. What if I draped the cable over the line? At least it wouldn't then be lying on the grass. So I did, and the results were fantastic! Not as good as a helper (person) or a robot, but way better than letting the cable get in the way all the time. Sort of like a giant version of this amazing gadget, which I've had on my ironing board for ages: http://tinyurl.com/ironholderminky
Gonna put my thinking cap on this afternoon and draw up a project to design a cable letter-outer/puller-inner, which would be wireless controlled by voice from a Bluetooth headset. I'll draw up the patent application tomorrow.
By the way, now that my chest has healed I can use the petrol mower again, so ordered a new blade as the current one was as old as the mower (12+ years).
However, the new blade doesn't look any sharper than the old one! So that was a waste of 11 quid.
