Probably not enough for you to notice except when the engine is idled down. The "priority side" of the flow divider will go to the steering torque generator, usually about 2 1/2 to 3 gpm. the balance then goes tothe rest of the hydraulic system. I'm not sure what the maximun (high engine rpm) is on the SMTA pump, but I'd guess no more than 10 gpm. Idle the engine down and you see what happens... there isn't much left for operating anything else. Hydraulic systems are not 100% efficient, so you can not depend on having anything left at a low idle. I have a Char-Lynn TG on my 240U and at idle, I do not have flow to raise the 3 point... I need to get to about 1/3 throttle for it to operate dependably. I imagine the SMTA has a larger pump, and since the TG will take the same with either tractor, you may hve a little to operate on at idle. I doubt you will raise a disk at idle though.... rev it up and it won't be a problem.
