[AT] Hydraulics Help

[Ronald L. Cook]

Dudley,
	Well, after reading the other posts, I really have more questions than 
comments.  Is the pump pumping when this is happening, or is the pump 
shut off?  Is the bucket settling under load or is it moving without a 
load and the pump running?  Open or closed hydraulic system?
