Massey Ferguson 7700s series

[Barley Brewer]

Anyone on here running a 7716/7718 alongside a 7720? All Dyna 6
Is the lift noticibly slower to raise in the 7720 than the 7716/7718?

Its possibly a software change needed I fitted bigger lift cylinders to a 6613 and made it slow ,changed the software to that for a 6616 which has that size fitted ,sorted. With the different ram size between the 18 and the 20 it is a possibility.

We have two 7620 and a 7618 - all VT, linkages all pretty much the same speed. It could be the linkage/spool priority is set differently between your tractors. Its in the left hand screen, simple to alter the %ages

We have a 7720 but no smaller frame to compare but it lifts slower than 6480 even with 150l/min pump the dyna vt will have a bit more flow as I think they are 190l/min. Just a lot bigger rams to fill on the bigger frame tractors

The linkage spool/priorities are set 100% to the linkage and making no difference

Got a 7720 and a 7718 both Dyna 6 and the 20 is slightly slower at lifting and dropping with the same weight we put down to having bigger Rams on the back

What is it you’re trying to lift and drop so quickly?

 

[Barley Brewer]

I'm not trying to drop anything quickly as thats very hard on machines but I'm just asking the question are the 7720's slower to raise than the 7716/7718

We’ve 7618 7718 7722 7720 and a 6716 ive not noticed they are any different but now you’ve mentioned it I probably will

We find our Dyna VT tractor hyd system are faster than the Dyna 6 ones we used to have

Yes because they are 190 litres/min.

Yes because they are 190 litres/min.

Our Dyna 6 ones were specific with big pumps in them as well think about 170 or so

Think the big pump on dyna 6 is 150
