parts availability on older tractors: My experience is mainly w/ JDs on older iron. We have several. Our newest JD is a 4320 built in '67? I believe? We did have to wait on the overhaul kit for the motor but only a few days. Believe it or not, our local Greenline dealer has a lot of the parts for our 2 cylinder fleet (build dates from the 1940's up to our newest 830 built in '62) IN STOCK! But I believe this may just be leftovers from the days before "just in time delivery" when places actually had an inventory.
The more poplular farm tractors (4020, 5020, 4320, 4440, 4230) would still have a large parts availability.
And let me tell you, that 4320 we just overhauled is one SWEET tractor. And other than maintenance and barring any abuse, I don't expect me or my 5 year old son to have to do anything major w/ it.
Sheet metal - well, don't know that we have ever replaced anything larger than a side panel or two, but they are available from Greenline and some aftermarket places. Also, ou might find a nearby Ag Auction like Brinkley's in Oklahoma. Lots of stuff can be found on their "Salvage lines".
I am like one of the other posters on clearing the mesquite. Chemicals may be the way to go for long term control. But to make a quick showing, you will need to rip them out by the roots. I'll say it again, dozer and a root rake. Mesquite can be very hard on $500 rubber tires.
