Moves, I think I understand your thoughts. My philosophy for several decades has been to spend as little as possible whilst enjoying a good lifestyle - even wrote a book about it. I use lots of modern gadgets (but draw the line at carrying a telephone in my pocket) yet still like to use the simple things. For example, my firewood supply for several years has been grubbed out olive tree roots, and I bust them up by hand. I have a couple of chainsaws and occasionally use them to shorten lengths that will split by hand, but otherwise just enjoy using my own muscles rather than buying fuel.
There is a mass of information on the Internet about "primitive" methods of doing things. Remember that in countries such as Portugal where I live there are still a lot of people who rely on animal power and do not have water or electricity in their houses. Of course there are many other countries in the same situation and if you can spend some time searching you will find lots of ideas. Countries such as Nepal, Bangladesh, India and Ethiopia have provided me with useful information. The sites are in English so no need for language skills.
There are also numerous old US sources. My computer skills are not good, so instead of trying to create links, which I would probably fail to do, here are some book or article titles that you should be able to feed into a search:-
Equipment - The operation, care and repair of farm machinery: Practical hints for handymen.
Farm that wont wear out - Hopkins.
Farmer's Cyclopedia of Agriculture, 1911.
Nepal Agric.Res.J.Vol.6,2005 - Development and Evaluation of Improved Feeders for Goats Suitable to Stall-fed Management System.
Handy Farm Devices and How to make them, Ralph Cobleigh. Available on the Small Farms site.
Home made Hydraulic Ram Pump. Details from Clemson Univeristy Extension Service.
Old Farm Tools and Machinery:An Illustrated History, Percy Blandford. On the AT Microfiche Reference Library.
The Book of the Farm, Henry Stephens.
Going through that lot should keep you out of mischief when you cannot work outside, and when you can, I totally agree that good gloves are a part of sensible apparel. I scoffed at wearing gloves until I moved to Australia in 1979 and found that it was sensible to wear them as everyone else did. Not really protection against a decent sized snake, but good against poisonous plants and insects, also the odd sharp nail, etc. Better to damage a glove than a hand.
Please keep us informed.
