[AT] In praise of hydraulics

[Cecil R Bearden]

I love hydraulics too and studied it in college, even specializing in 
hyd power systems, in the few hours I could specialize in, with a B.S. 
Degree in AG Engineering.

However, much as I love hydraulics, I do not like using hydraulics to 
engage PTO clutches.  As hyd pumps wear, they have less pressure output 
and do not fully engage the clutch.  My 2-105 white is the same tractor 
as my 1850 Oliver.  The White has a hyd engagement on the PTO and the 
Oliver has a lever to engage the same clutch.  The White has had 5 
revisions to the sealing rings on the clutch piston.  I have rebuilt the 
White clutch pack.  The Oliver has more hours on the PTO than the White, 
and never been touched..........   Just a little less convenient to move 
a lever than move a hyd control valve.
