The present invention relates to the technical field of
agricultural machinery, and in particular to an implement adjustment device of a three-point suspension mechanism, comprising an implement hydraulic
system and a vehicle body for
towing the implement, the hydraulic
system comprising a lifting cylinder, an oil inlet pipeline of the hydraulic
system and the lifting cylinder being connected via a
reversing valve, a
piston rod of the lifting cylinder being connected to the implement, a
handle of the
reversing valve being connected to a driving mechanism for driving the same, the content of this patent realizes
servo control of
tractor implements, realizes the correspondence between the position of the control
handle and the height position of the
tractor implements, the position where the
handle operating rod is placed corresponds to the height position of the implement, there is no need to manually supervise the implement position during the adjustment process, and the efficiency is high.
