620 jd hyd.

Trying figure out the reason for super slow drop speed on the 620. Hooked to pull type plow with cylinder and it literally takes 20 seconds for plow to drop. Hook to different tractor, problem goes away. Any thoughts ?

Are you using a one way or two way cylinder? Also are you moving the lever to full detent or just moving it enough to activate the cylinder? These answers may help us to diagnose your concerns.

Two way. And have tried both full detent and the other way. Like i said we hook up to the 630 or 730 or even the 520 and it works fine.

Remove and Transplant the couplers between tractors and try again.

Have you checked the lower metering adjustment, meant to adjust speed of drop...??
(Lower Rt Side, under the Rock-shaft arm)..
It may be set for a heavier piece of equipment and drop too slow for what you have on it..

Checked the metering and was set wrong for our application. Adjusted and works fine now! Thanks all.
