I have a 77ish Deere 2640, mainly used for Bush Hogging around the farm.
My local radiator shop guy is getting up there in years, and will likely retire soon, so this year I took the radiator off and had him boil it out and get it good and clean.
Put it back on, filled with reg green Prestone and distilled water 50/50. I've mowed a couple of times with it and everything is working great, engine is staying nice and cool.
Then a guy on another forum mentioned that I needed to put in some coolant additive to prevent cavitation and cylinder wall erosion. I looked it up and it does appear to be a thing. That said, in talking to several local farmers, the guys at NAPA, and even diesel pickup owners, nobody around here has ever heard of this.
I did find a bottle of Napa 4058 on the shelf, which a couple of forums said to use, but the guys at NAPA (who are usually pretty good around here since it's a small farming town) knew nothing about it.

So, my question is, should I be concerned about this on a late 70's low HP tractor like this, or can I just run my 50/50 mix of Prestone and distilled water? I don't know what was in the tractor when I drained and removed the radiator. It was whatever was in there when I bought it 10-12 years ago.

Today's Featured Article - Grain Threshing in the Early 40's - by Jerry D. Coleman. How many of you can sit there and say that you have plowed with a mule? Well I would say not many, but maybe a few. This story is about the day my Grandfather Brown (true name) decided along with my parents to purchase a new Ford tractor. It wasn't really new except to us. The year was about 1967 and my father found a good used Ford 601 tractor to use on the farm instead of "Bob", our old mule. Now my grandfather had had this mule since the mid 40's and he was getting some age on him. S
