I'm probably a little famous on this site for my utter dislike of 743 or any 40 series. You might as well get an 8n for a loader tractor and a '46 power wagon for a 4x4 truck for comparison. If this was 1990, my tune would be different as they were good machines when new. Today they are terribly outdated, often worn out and simple not worth the money to stick a ton in. Running and working $3500 is top dollar, paying more for one is stupid. I've said before, if you have owned one for 20 years and it has been go to you, then they are an OK machine. But dear god don't buy one, especially if you want to make money with one. Also who ever says they are easy to work on is nuts. A 753, 763 and so on are night and day easier to work. 753 or newer and find a G series if you really want attachment capabilities.
