7530 speed problem

[Phil-the -farmer]

On way home from mowing yesterday , tractor would not get up to full speed. It's 50k autopower box. On the roller on the gear shift it would increase the speed to 50 on the side controller but the ring of orange lights showing potential speed on the dash would only show about 37.5k .
Then had warning flash up for filter restriction, pulled over and switched off for a couple of minutes before setting off again, no more filter warning but still no speed.
Hope this explanation makes sense to the collective brains out there, any ideas? Speed sensor gone wrong maybe? 500 hours since filter change so should be ok.

Were the brakes slpit? On the r series it will do what you say

It's as if it doesn't know the lever is right forward then ?

Strange one anyway

Spoke to the local fitter, he said about the split brakes but that's only on the newer series. Going to change the filters again just in case there is a restriction in the flow of oil causing a de rate of some sort. See what happens after that.

Now Then..
Have you looked to see if there were any error codes??
Does it have an engine cruise setting like the Powrquad tractors do??

No cruise control, first time it did it , hydraulic filter blockage flashed up . Switched off for a bit. Started up kept going, no warning signal but no speed above 35kph. Wondered if it went into limp home mode or something. Will get new filter element on Monday to see if it cures it.
