</font><font color="blue" class="small">( Since my tractor is hydrostatic.. your saying I should be able to pull my disk set at 1000 RPM's as easily as when I'm at 2600 RPM's.. my experience is.. that is not the case.. the disk set won't budge at 1000 RPM's.

You are introducing more variables than my comment refered to. I was refering only to a hyd pump output in a closed circuit. In a closed circuit, and a positive displacement pump, max pressure will be achieved no mater how fast or slow the pump is turning.. it's not a flow issue.. etc.
Now.. the hydrostat tranny is not the same as a hyd pump and hyd cylinder application.
Also.. your reference to 'easier' is subjective. I do believe that your tractor, if running at hi idle.. say the 1000 rpm,in th elowest range, and if you don't stomp the speed pedal down all the way, but rather just barely step on it.. i do believe that the tractor will crawl forward.... If you stomp It.. i think it would try to stall.
I don't own a hydrostat, but have driven them, and believe that is the relationship between the throttle and the speed control.

Try what I sugested.. set rpm to 1000, and then select lowest range, then just nudge the treadle down just enough to get forward movement.. I believe it will move... if not.. that would be reason number 87 why I wouldn't own a hst tractor. At idle, the pump should develop max pressure that the system is capable of,, flow rate is another story entirely.. I'm not saying ti will move as fast as at 2600.. but only that it will move. ( out of curiosity sake.. post back your results.. )
