Just finished a job two days ago building a gravel pad for some grain bins. Used my 973c and champion grader to do it. Cleared a row of trees that would've been in the way of the bin pad, took my grader with the ripper and ripped the roots so they hopefully wont come back. I had a bunch of gravel stockpiled just to the east probably 30-40 feet away from the beginning of the pad. The pad was about 200 feet long, and 25 feet wide. With a small drainage ditch between the existing row of bins and the new pad so they can install a drainage tile next year. I stripped the top soil and organic off the surface stockpiled it at the end with my track loader. Then i went bucket by bucket hauling the gravel onto the pad. And let me say that if anyone remembers the modulation issue i was running into before with lack of fine control lowering the arms down. Well with a heaping bucket of gravel. Modulation was absolutely terrible.
With a full bucket of gravel up at eye level in the cab. I could push the joystick forward 1/4" and it would start to slowly go down, but as soon as the bucket pins get lower then the top loader arm pins by the cab. It drops the bucket as if I'm mashing the joystick into the detent. Maximum speed for dropping.
I'm starting to wonder if the pressure from the loader arm cylinders is being fed into the pilot system and compounding with my pilot pump pressure and opening the valve far more then i am commanding? Is there a port/regulator/valve that controls the flow that could be faulty?
