This needs some discussion. I apologize in advance for the length & appreciate your patience. Let me describe what I think you have and why you do not have full control over you loader while drilling with the PHD. Of course I may be missing something and if so please set me straight after I finish. You have an open center hydraulic system on the MX5100 as most tractors do. You have one hydraulic pump that powers everything except for your power steering and your 3pt lift. Total of 3 pumps. Your loader control valve and anything your loader does under hydraulic control (aside from gravity drop) gets hydraulic flow via "power beyond" from your main hydraulic pump. Your remotes in the rear are also fed from your main hydraulic pump. That entire system (off the main hydraulic pump, putting aside power steering and 3pt lift pumps as they are out of this picture) is open center -- meaning that when you move a position control, that valve opens and flow goes to that controlled destination only and all other destinations in the chain wait. I'll mention typical circumstances first and then possible exceptions. Typical circumstances are: While you are raising the FEL you have no ability to simultaneously curl the bucket and lift bucket tip load by curling. They can happen very close together but not simultaneously. When you forceably dump the bucket (for example lifting the tractor front end off the ground) you cannot simultaneously, forceably, lower the FEL frame and lift the tractor both with the bucket tip forced down dumping and with frame force downward. When you use the "3rd function" to close a pinch bucket clamshell (or to drive an hydraulic motor) you cannot do that simultaneously with raising the loader nor forcing it down. In effect, with one main hyd pump feeding everything, the hyd system has what I call a one track mind. I hasten to say that gravity gets into the picture and often makes you think you have simultaneous hydraulic forced control 2 places. For example you can dump the bucket (assisted by gravity) while simultaneously raising the FEL frame. That gives the illusion of 2 concurrent hyd controlled actions. You can lower the FEL frame with gravity while doing any ONE of many other things under hyd power. There are of course many other examples. Exceptions: Some manufacturers devise ways to compromise one-track-mind hydraulics. One is to introduce a flow control splitter or diversion valve that splits the main hyd pump output and sends X% to one destination while sending Y= (100% -X%) toward another destination without either becoming zero. That flow control mechanism is (what I consider a complex option) available with some brands, notably New Holland, some high-end Kubotas, options on larger Deere, etc. Of course almost any mod to hydraulic plumbing can be had for a price (factory or 3rd party) and none of this is cheap. I'm betting you can lower your FEL by gravity while driving your PHD auger but that you cannot pick up the FEL while augering. If you can simultaneously do both, then a flow control valve has been installed in the picture and the two actions (FEL lift and augering) are sharing the flow -- the FEL raises more slowly if you are augering and vice-versa. That has to be the case because you only have one main hydraulic pump serving all these functions. Most of the time we are happy with one-track-mind hydraulics because gravity is a great helper in many examples or because going back and forth between various powered hydraulic functions isn't too bad of an interruption. If you understand my description, please tell me if you have a flow control valve involved (a means of simultaneous sharing of the single flow) or how it is, otherwise, that you simultaneously do multiple hydraulic powered actions with a single pump. What a mouthful -- your comment ?
