[AT] Pasture cleanup day

[Dean Vinson]

Dean, thanks--that's very good advice.  I had planned to do exactly as you
suggest with the boiling water, but hadn't thought to check the thermostat
or the actual coolant temp at the radiator cap.

My dad is coming down this Saturday for his first visit to my new place, and
I haven't told him about the 620.   I know he'll get a huge kick out of it
when he sees it.  He had a 50 and an A for a while quite some years ago and
is a big fan of these old machines.

Dean,

When and if you take the temp gauge out I would suggest one final test
before ordering a new one.
Bring some water to boil and insert the sensor end into the boiling water
and see what the gauge reads. When I first got my 620 I too thought that the
temperature gauge wasn't working. I found out later that the thermostat had
been removed and a replacement had never been inserted. It took plowing with
a 3 bottom plow in heavy soil in hot weather to get the gauge to move. The
gauge was fine. The tractor was just running too cool. Not good for the
engine.  You might also want to check what the coolant temperature really is
with a thermometer at the radiator cap and see what temperature the tractor
is really running at. The 620 has a water pump and the cooling system is
pretty efficient if the system/radiator is in good shape.

The real art of conversation is not only to say the right thing at the right
time, but also to leave unsaid  the wrong thing at the tempting moment.
