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.
