Selective lever controls for belly pump

I have one of these on my "M" and it's quite an obstruction. I'd like to remove it and replace it with a regular operator's control rod and bracket. I must admit that I don't know squat about hydralics, so I have a few questions.

First, what was the purpose of changing over to a selective lever control. Was it due to using certain kinds of implements, or equipment? If so, what kind of implements or equipment? Or was it just a simple kind of upgrade from OEM. Just curious.
Second, I don't intend to use the tractor for any kind of farm work. It is mostly going to be for show and parade. But, I would still like to have a belly pump that's in good working order, and know that I can depend on it if ever there is a need for it. Right now the dip stick shows dry for the reseviour, so I'm assuming the belly pump is not working. Is it OK to run the belly pump dry without hurting or damaging anything?

That is a selective valve to run the front and
back cultivators sepatetly.Left slot runs the
rear,right slot runs the front,center slot runs
both.It only works with a oneway cylinder.Leave it
on!It is something unusual most folks have never
seen.learn how to use it.If you just HAVE to
remove it,someone out there will want
it!Garanteed!No,you cannotrun the belly pump with
no oil.fill it with oil,pull the handle,see if it
squalls/loads the engine.remember,the clutch must
be out as it driven by the transmission,not the
engine.
 
You must have oil in the belly pump reservoir if you are running the tractor. The pump runs all the time that the clutch is engaged, so it needs the oil for lubrication. The only exception here is that it's possible someone took out the drive coupling between the transmission and pump that drives the pump, in which case the pump would not run.
 
There is a removable drive coupler between the transmission and the belly pump unit.

Check up inside and see if the coupler is installed. The reservoir may be empty because the pump is disconnected.
 
Thanks for the feedback guys. Most, most helpful. BTW, even though the dipstick showed empty the reservoir was not empty and the coupler is indeed connected. The drain plug which was loosely just hand tight was removed, and out came about a quart or so of oil. Obviously the oil had been seeping out through the loose drain plug for I don't know long, thus the low oil.

I looked through all my manuals, and couldn't find anything on oil capacities for the reservoir. My I&T manual does show 7 qts. for the smta, and 8 qts. for the w6ta, but fails to mention anything abut the M. Does anyone know for sure?

Patrick, My Farmall M Owner's Manual states six quarts for the "Lift All" which is the name of what we all refer to as the belly pump. I think 30W non-detergent oil is what is recommended for the pump as that has been discussed numerous times on this forum as it doesn't foam like the detergents will. Hope this helps, Hal.

The drive coupler on an M is NOT removable without dropping the belly pump. An H, yes. An M, no.
 
(quoted from post at 12:43:13 09/04/12) You don't have to put it back in, do you?

Many M belly pumps have been disabled by dropping the pump, removing that coupler, and then the belly pump is re-installed for use as a reservoir only when converting to a live hydraulic system. Sometimes the entire pump mechanism is removed.
