Interesting discussion with good points on both sides. I'm with SS with hand shearing to get as good quality fleece as possible, but where the big sheep owner just needs the wool off, or it's going to the Wool Board for carpets then machine clipping is quicker, therefore cheaper. For very small scale sheep keeping I see no place for machine shearing at all.
Being even older than Robert
(just) I can remember when we had a dozen men working on a small farm which now would not support a single worker full time. We had some mechanisation in the form of tractors, combine, implements, no horses as post war, but all jobs such as hedging and ditching, beet singling, mucking out, were done by hard manual work. Our men were worn out before their time by modern standards, but compared with a hundred years earlier they had it easy.
We built our stacks of bundled straw by hand, and thatched with the same straw. I remember it as fun and I think it was a high spot for the men too. They knew how to pace themselves (when my Dad's back was turned) but that is the way to get the work done - slowly but continuously.
I can remember having lots of energy and being able to put in a never-ending day, but nowadays, when most farmers are over 60, that energy is gone and a bit of mechanisation is wonderful.
What neither of you has mentioned is that as we run out of oil, and SS you will be around when this happens, we will have to go back to some of the 'old ways' of manual work using more people. There are so many unemployed people in Britain that a bit of manual work for them would surely be one answer to both problems.
