gradually dropping means that the problem isnt in the pump or filter, it should be the lift cylinder valve or piston rings.
Dont you have warranty on this 2010 model ?

1967 Zetor 3011, technically new, needs paint
1973 Zetor 5718, repainted and shiny, rebuilding it bit by bit
1978 Zetor 5718, rough but full options !! (synchro box, power steering and 1000rpm PTO) wink

If hitch mode is Draft or Mixed it can do that with heavier machines. If selector lever is Position mode, it should keep it up. Does it have pneumatic control? If pneumatic valve electricity feeding has problems? Or then it is lift cylinder seals. Valve it can be too, but its rare problem with Zetors.
