Use and adjustment of the three-point lifting mechanism
(1) When the tractor is ploughing, in order to ensure the quality of ploughing, you shall
adjust the length of the upper pull rod, lifting rod and limit chain according to the
plow’s connection requirements and cultivation needs of the plough. In general, the
upper pull rod is adjusted to keep the plow front and back horizontal, and the left and
right lift rods are adjusted to the left and right horizontal, and the left and right limit
chains are adjusted to swing the horizontal direction of the plow.
(2) The plow with belt wheel is adjusted by the belt wheel. In the first plow tillage, the
first round of adjustment, when one of the plough is till to the required depth, adjust the
upper pull rods to ensure plough plane parallel to the ground, and then adjust the left
and right lift rod length, make each plough tillage the samen depth; When ploughing the
second plough, the ploughing of the tractor is caused by the running of the side of the
wheel, which causes the ploughing depth to increase greatly. The length of the lift rod
and the length of the upper pull rod should be adjusted so that the furrow ploughing is
consistent.
(3) When the tractor is equipped with farm implement, the left and right limit chains
limit the deflection of the hanger rod and the farm implement in the process of use. In
order to ensure that the plow is automatically returned to the origional position, a
certain amount of deflection (about 5cm) is required, so that the deflection cannot be
too large, so as not to touch the tire. When the tractor rotary tillage, it can be adjusted to
the unbiased pendulum. Tighten the lock nut after adjusting. When do not hanging the
farm implement, use the lower rod limt spring to connect the two lower pull rods to
prevent the wheel from touching the tyre.
(4) When the tractor driving long distance with farm implement, in order to ensure the
safety of driving, the following requirements should be carried out:
Adjust the length of the upper pull rod to meet the transport requirement. When the
lifting height of farm implement is determined, the left and right limit chains should be
adjusted to make the farm tools swing less. Then, lock the locking nut on the upper pull
rod and the locking nut on the left and right limit chains respectively. Finally, rotate the
hydraulic lock handwheel to the bottom position.
