New Holland T4.75F Operator's Manual page 124

Operation
The lift works in position control. It is operated with one of
the two levers (1) or (2) that command the rear distributors
with the "DIVERTER" function, that is to say by pressing
the button (3). The levers and distributors are marked with
the same colour to facilitate identification.
Press the button (3) and move the lever of the same colour
in which the connection was made forwards to lower or
backwards to lift the implements connected to the front
lift.
NOTE: On release, the levers automatically return to the
central position. If it is necessary to work with the lift in
the float position, move the levers beyond the stop where
they are held by a special catch (detent). From the float
position, to be able to lift the implement the levers must
be manually unhooked.
NOTICE: When working with implements connected to
the lift, pay attention to the operations as they increase
the dimensions of the machine.
