[AT] de-greasing disc brakes

[charlie hill]

John and Farmer,   I never could convince my uncle that the governor
was put on the tractor so that you could run it wide open without harming 
it.
He just didn't understand the concept of a "governor".  But then again he
was born the day the Wright Brothers flew the first airplane and since
eastern NC has always been behind the curve, or at least since the war of 
Northern
Aggression,  there were lots of things he'd never seen and didn't 
understand.
He was a small farmer and never owned a combine or a grain truck.  One time 
he
had a fairly large amount of tobacco to haul to the warehouse at one time 
and he
borrowed his neighbors 2 ton grain truck.  He wasn't sure he knew how to 
drive
it so he got me to drive it down to his "pack house" where the tobacco was 
stored.
I don't know why I did it but for some reason without any logic other than I 
was a
teenager, when I backed the truck up to the pack house I dropped the 2 speed 
axle into
low range.  Well, when it was time to go he had watched me drive the truck 
far enough
that he decided he would drive.  Here we go in low range.  I tried for 5 
miles until he dropped
me off to get him to switch to high range.  He was hard of hearing and I 
just couldn't get it
across to him.  He kept telling me we were going fast enough.  (his normal 
speed was about
30 mph).  Finally he  put me out at my pickup and went on about his way to 
the warehouse
that was about 25 miles away.  The next time I saw him I asked him how the 
truck did.
He said "that things got a lot of power but it sure does love gas".  Since 
he had already
taken it back home I didn't bother to try to explain.   I just hoped he 
hadn't hurt it running
it that far in low range.

Interesting that you had good luck with the Farmalls with disc brakes, those
are the ones dad fusses about the most! Guess he heard too many complaints
about them while standing on the other side of the parts counter. I will say
this, thank heavens for internal disc brakes--not only do they work good,
they last a mighty long time. I'm glad I grew up on that style tractor!

Regarding the full throttle situation, all the tractors and combines here
were run full throttle with a couple exceptions. We never ran the baler at
full throttle, one particular bushog was only ran about 2/3 throttle (we had
more tractor hooked to it than its gearboxes could stand--it was bad design
on the bushog manufacturer), and cultivating tobacco when it was small--that
was sometimes not much more than a fast idle. If we backed out of the
throttle during tillage it was because the land was too rough or the corner
of the field was too tight. On the flip side however, my dad has NEVER ran a
lawnmower at full throttle. I have to encourage him even today to speed the
engine up a bit.

I have always liked disk brakes. I guess the first tractor here with them
was the MF-65-D-HA bought new. Next was the MF-165-D-HA that the 65 was
traded on. It's still here. Many years ago we bought a very nice New Idea
mounted picker (we had always used pull type pickers) and the friend that
had owned it had used it on a Farmall M. We went looking for a good Super M
to mount it on since we wanted the Farmall Super M improvements. More HP,
thicker radiator, bigger clutch, live hydraulics and disk brakes. Worked
well. Later I found my Farmall Super MTA to use with that picker for the TA
and independent PTO. It also has disk brakes. A bit later we picked up the
Farmall 400 (just because)  :-)  and it has disk brakes. I think the only
other tractor here with disk brakes is my Minneapolis Moline R. Its disk
brakes also work very well too.
We did have a bit of a disk brake problem with the Farmalls. We bought new
disks from Tractor Supply Stores that were only a small part of the price
of the ones from IHC. They looked very good but just wouldn't grip well
enough. We solved that by buying a full set from IHC and using one IHC disk
and one TSC disk together on both the Super M and the Super MTA. They have
always worked fine since.
In regards to throttle settings... here we have always used full throttle
for about any soil preparation job like plowing, disking etc. PTO jobs just
depended on the job. Cultivating (when we still did it) was usually fairly
low RPM unless the crop was pretty tall. I always felt that the engines
were engineered to run at maximum governed speed when pulling the maximum
load. I was always a bit surprised when guys talked about never running
full throttle. (shrug)  A lot of clutches use weights to apply more
pressure to the disk at higher RPM's and if you run at maximum load at
lower RPM's I would expect more possibility of some slippage.
