Shut the throttle a bit

No, drop rate has no effect. Maybe inline oil restricters to reduce the flow to the hydraulic rams?

r series deere can slow down the lift, about time too much kinder on tractors and implements and doest heave great holes when lifting sumo/subsoiler etc

Good suggestion. I used to drop revs right down on a 7810 pulling TWB subsoiler. Stopped it lurching out and banging the packer roll.
Could be worth a go. Will have to hitch up and try it
. Was hoping for something a bit more adjustable and foolproof for the old boy.

A one way adjustable flow restrictor in the line to the lift cylinders might do it.

I've never found it a problem. Just use the slide control and push it down at the same rate as you want the arms to drop.

Yes.. you can set the ram sizes to different specs when you calibrate the hitch.. which model ?. 00 series you cant do much with the speed except maybe the ram size adjustment before the calibration.
Ill have a look when i can for an easier diy fix when im home. I think there will be an address with a value that can be altered for speed adjustment. Give me a few hours ill look later tonight.

Its a 7800, year 1997 I think. Thankyou, much appreciated.

Ffs I thought these jds were the dogs danglys, there's a dial on mfs with electric linkage to slow lift rate same as there is for drop rate

Would you like fries with that order of pee to go or just the awkward point that in the early 90s neither MF or JD fitted variable rate of lift?Ffs I thought these jds were the dogs danglys, there's a dial on mfs with electric linkage to slow lift rate same as there is for drop rate
I blame the plough, cracked our DP7 a couple of times with a MF 3645, although that was turning over too fast rather than lifting.

My 1991 3630 has variable lift rate
You can turn the flow down on the spools to stop the plough turning over too fast aswell
but yea sounds like a shite plough to me
Which knob alters lift rate?My 1991 3630 has variable lift rate

I haven't seen that function on a 3600 or 3000 series linkage control before or is it not on the computer box with the other controls?
Slowing down turn over made the plough last indefinitely, but the convenient spool was the one without a detent, so had to hold it longer. Those masseys had a lot of good features, but they hadn't got the ergonomics to match them.

The big one when you turn it slowly
