never breaks down sitting in the shed.....I stock a full set of bearings and 2 left and right shear hubs. Blades, nuts, bolts.. Simply have to be self sufficient incase of Saturday morning of a long weekend.....shite always happens, one reason contractors, with newer machines, look attractive.
and that is the downside of old kit, it breaks down, usually at the most inconvenient time.
we had a tine bearing go, in our p/harrow, went to get at it, it was under the gearbox, loads of nut/bolt removal, got down to bearing, couldn't extract it, without a 'special' tool, £456, got one made up for £50, bearings were half price, from local 'specialist' supplier, used to be express bearings, diff name now, than from dealer. Bearings went on our mower, 1 was 'special', had a groove for a circlip, find one at local main dealers ? 48 hrs delivery to dealer #####, found another bearing supplier, not specially ag suppliers, 3 on shelf, half dealer price,
But, as you say, you really don't want a breakdown, in 'action', and often you do
