I don't have a skid loader, but do have a couple implements that use large hydraulic pumps on the pto which pump fluid directly to motors on the implements. As long as the pto is turning, the motors run. These systems run, and are isolated from the tractor hydraulics. One ditch bank mower does have a couple hyd cyls that control it which are run separately thru the remotes of the tractor, but these are still separate from the aux pump system. Hope this helps.
