They can still do a dayís work. When I started farming my loader tractor was an M. She was awful good to me for 800 bucks. When I started buying new tractors I took the loader off and put it on the mixer grinder. That old thing still grinds feed every couple of weeks. Change the oil once a year, clean out the oil bath, good to go. Iíve never even opened the distributor - I figure donít mess with it if it ainít broke.
Funny story - the starter would jam up on it about once a month years ago when I used it everyday. Wouldnít you know, the day I convinced the wife to get into the bucket to get all of the apples that starter jammed with her at the top of the tree. The wind started to blow and it started to drizzle. I walked off to the shed to get the wrench without saying anything. I was hoping it would take her a while and I could quick get it fixed and she would never be the wiser. When I got back to the tractor she was saying goodbye to the dogs down on he ground because she was sure she was going to die up there after hours just waiting for a lightening strike.
After that I put the starter on it from my parts M. Also, she wonít get in a bucket. I have to have her lift me up to change the yard light bulbs. You want to talk about a quick elevator - she doesnít get feathering. When itís time to come down she throws the joystick forward. In case you wondered, a big tractor has enough down pressure to make your shoes leave the ďgroundĒ when she lets you down. Iíve learned to just lay down in the bucket a scream that I am ready to meet the Lord.
