D21 hydraulic ?

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   What pressure should be at the hookups? Will a D21 struggle to raise modern heavy duty equipment? Spent the day yesterday hooked up to a 18 ft, I dont know what it is really called, renovator, straight disc blades then another row of disc then two rows of spinning leveling drums. At first thought the clutch was slipping thankfully I was spinning out. I ran her for all it could pull for six hours. Had to stop to replace a O ring below the hydraulic pump. But even when I first hooked up, relevilty cool, it fought raising this thing up or folding the wings.

	Remote outlet pressures are to be 2,200 psi with the engine at full throttle and warm hyd oil. Some have been adjusted upwards to 2,400 psi and that would be the max. Modern implements sometimes require 2,900 psi. Sometimes, not always. Wings to implements are oftimes orificed to actually make them slow, for safety reasons.

	There's also a possibility you might have hydraulic coupler mis-match. And also a possibility that your 12 to 14 GPM hydraulic pump doesn't look so good on a modern implement that may have many large diameter hyd cylinders and requires 25 or 50 GPM to make them work at a decent speed.

	It does have large diameter cylinders and long. Taking the 7060 today to give it a work out. I'm in a 70 acre field that just got the beans out. Water pump just in, welded and sealed the cab. This tractor hasent seen 180 thermostats for awhile and I'm taking her to a pull. Edited by whatscooking - 2 hours 25 minutes ago at 11:48am

	7060 is a 2500 psi system with 17 GPM out of each remote valve IF THEY ARE SET CORRECTLY with the rabbit/turtle levers under the seat. One speed lever for one remote valve. Three valves and only one rabbit/turtle lever?? you can only adjust ONE valve for speed/flow.
