BH controls, Is this normal?

[ragkar]

On my BH, I've noticed that most of the motion is concentrated in a half inch of the control knob arc.
That is, the controls of the boom and dipstick can move about four inches. However there is no motion of the arm until I deflect the control about three inches. Then the next half inch or so controls the arm motion. This makes it difficult to avoidjerky arm motion. Is this normal?
I don't have experience with other bh's so I assumed it was normal. However, my tractor is now in for 50 hour service and if something's wrong, this is the time to complain about it.

sounds like something may be loose or improperly installed...the more you push in a direction, the more flow there should be, sounds like your valves open all at once.
