Hi, ewk.
Long grass, huh? You may want to check your radiator core to see if it is blocked with grass and 'chaff', etc.. If it is blocked, you can blow it out with compressed air or water.

You can slow down the build-up of this debris within the core by placing a sheet of fine metal insect screen in front of the radiator and REGULARLY scraping off the build-up of trash from it. You may quite surprised at the amount of stuff that collects there. And how quickly.

Failing that, one of the more common causes of over-heating amongst older tractors and vehicles is simply that the tubes in the raditor become partially or even totally clogged with corrosion scale, chemical deposits from the water that has been put into it, stuff like Bars Leaks, pepper, Chemi-Weld etc., that has been put into it to 'cure' various problems or, in the case of one 'corrosion inhibitor' which appeared BRIEFLY on the market DownUnder, the corrosion inhibitor or anti-freeze itself.

Another cause can be oxidisation of the metal of the core itself. This puts a fine coating of oxidised metal between the metal and the passing air and can severely restrict the metal's ability to pass heat to the air. If most of the paint is gone from your radiator core and/or you can see any fine, often white, powder around the core or the soldered joints of the tanks, this may well be your problem, or at least part of it.

Hope this helps.

You have a wonderful day. Best wishes. Deas Plant.
