So - now you'll need to join the Old Lawn Mower Club!!
We also have a postage stamp size lawn at home, so my husband volunteered to be the field warden on our allotments - so he could use his Atco Standard 1926 - and since then he's received donations of other vintage and classic mowers (all built to last) which he uses on our site on a regular basis (we have a community lawn area and a trackway with a central grass area which needs cutting). We have Several Ransome's models, a Webb's, a couple of Suffolk Lawn Mowers models - and just this morning he found a Ransomes Ajax mark 5 on a plot being given up and the mower left - so no doubt it'll get restored - and join the other push mowers he has restored which are on 'free use' by our plot holders.
