on the 3-point lifter shell is improperly
installed or damaged
With the 3-point
lift lever at
lifting position,
the hydraulic
distributor
makes a loud
noise
(1) Because of improper adjustment, the
inner lifting arm props against the lifter
case to open the safety valve
(1) First measure the lifting height of the
farm implement. Then readjust and shorten the
force/position adjusting rod to make the highest
lifting position lower than the original position
The 3-point
hitch has
no hydraulic
pressure or
weak output
(1) The oil cylinder inlet line has
been disconnected
(2) The front cone and conical hole of
the speed lowering control valve have
not been sealed tightly
(3) Lifter is in the neutral lifting position
(1) Tighten the lowering speed adjustment knob
