[AT] Allis 7030 running warm

[Cecil R Bearden]

The foam is good around the radiator. I added some by using those 
"noodles" for swimming.  Wally World closes them out in the fall for 
$0.25 ea.  They work great around cab trim, pipe insulation and to 
prevent hyd hose chafing.  I remember the last time this tractor was 
used it was pulling a 15 ft Batwing mower or a swather.  It may have 
some trash from prairie hay in the radiator.  will blow it out shortly, 
just waiting on daylight.  The radiator may be clogged inside as the 
water in this area is really hard.

The heat gauges are connected to the 2 ports in the thermostat housing.

I am double sometimes triple disking this ground, and the disk is only 
going about 4 inches the first time.  The tractor is then running on 1/2 
fresh ground and 1/2 disked.   I may put the duals on if it would save 
some time on getting it done.  I know there is some wheel slip, I can 
feel it.

I think I will just run in a lower gear.  Problem is I can either run 
about 4 hours a day and get a decent nights sleep, or run it 8-10, and 
sleep next week when my back returns to normal.  After 4 hours of riding 
in rough ground, I lose the feeling in left hand altogether.  Right foot 
toes are asleep most of the time, but it gets hard to get out of the cab.
