Tractor mf7722 Dyna 6

Good evening everyone, I'm asking for your help to solve a problem on an mf7722 dyna 6. the tractor does not exceed 1400 revolutions per minute. It has already been scanned and changed filters.

Welcome to the forum.
Does it just limit out at 1400 RPM's or does it start running rough once you reach those revs?
I'd start by checking all the linkages to make sure you're getting full travel.
