H is overheating

I was cutting dried pararie grass this afternoon with a #9 McC 6ft sickle mower. I had it in 4th and set mid way. It finally started heating up after around an acre when I was raking it with a McD Sulkey rake. I intend to use the grass partially as filler in raised bed taters, and partially to run through my 1950 Case 140 bailer when I get someone who can tell me why it dosnt tie.
Anyway, it started boiling over. The fan was turning great. QUESTION. I had the gas barely cracked open at the bowl. Would that cause it to overheat?
 
Most common overheating when mowing is caused buy a plugged radiator screen. The seeds and dirt will sop up the core pretty quick. I have a piece of screen wire that I tarp strap across the grill when mowing. Of course it could be a cracked head, or bad head gasket.

Exactly. The fluff from a cottonwood tree will do the same thing.
 
Given that trash blocking air flow through the radiator is the likely problem, it is worth noting that a lean fuel mixture can cause overheating. The fuel shut-off should be fully open when running the tractor. At all times, it should either be fully closed or fully open. If you think it needs to be somewhere else, you need to find and fix the real problem.
 
I am also a proponent on all on or all off on sediment bowls, that way you are not counting as much on the packing to seal.
 
I've never seen an H or M overheat without a lot of hard work. I grind feed with an M and when it reaches 100 during the summer it finally gets up into the "run" area on the gauge. This time of the year the front is covered with a feed sack so it will get to the middle of the "cold" area. They just don't get hot very easily.

Grandpa ground feed with an H. It "overheated" on him one day while he was grinding. The next time it did it he called the scrap man. I was so mad when he told me that. I couldn't convince him there was nothing wrong with it but a head gasket. Sure enough, the scrap man had one nice Farmall about a week later.

You are either plugging the rad or have a head gasket in need.
 
The grill is NOT plugged up. I thought the rad would be low. At 70, I find it hard to climb up to take a look to see just how low it really is. I put a 1/2 gal of 50/50 antifreeze in it, then stuck my finger down the hole I could feel fluid over the first joint. Is that too high?
 
=================================

I also think it might not be getting enough fuel.....that gas shut-off needs to be wide open when using the tractor or firmly closed when shut off, it was never designed to be set partly opened.

An H or M is very hard to get too hot if cared for properly, almost impossible to get them to overheat.
