Hydraulic system
The hydraulics system is a vital component of the tractor 3 point
hitch. It engages and operates the hitch, enabling the lifting and
lowering of attached implements. Pressurized hydraulic fluid is pumped
throughout a complex system of pipes and valves to generate the power
needed to move the hitch.
The heart of this system is the hydraulic cylinder, where fluid is
forced under immense pressure, creating a pushing action that drives the
movement of the lift arms. The amount of hydraulic fluid released
determines how far the lift arms are pushed out, thus controlling the
height and the depth of the attached implement.
Furthermore, the hydraulics system also contributes to the stability
of attached implements. The system can balance the power on both sides
of the hitch, ensuring the attached tools do not tilt or slant, even on

How Tractor 3 Point Hitches
Work
Attachment and
detachment of implements
The process of attaching and detaching implements on a Tractor 3
Point Hitch is relatively simple but requires careful execution. The
first step involves lining up the tractor’s hitch with the implement’s
mount points. These main mounting points typically consist of two lower
links and one top link.
To attach an implement, the operator must slowly reverse the tractor
towards the implement, ensuring the lower links are aligned with the
implement’s connection points. Once aligned, the links must be securely
connected and fastened to prevent accidental detachment. The top link is
then connected and adjusted to achieve the correct operating angle for
the implement.
The detachment process is essentially the reverse of the attachment
process. It’s crucial to ensure that the tractor is turned off and in a
stable position before starting the detachment procedure. The top link
is usually the first to be disconnected, followed by the lower links.
Ensuring the ground around is level aids in a smoother and safer
detachment, minimizing the risk of the implement tipping over or
damaging the hitch’s components.
The process may vary slightly depending on the type of implement
being attached or detached. However, the principle remains the same:
secure attachment for efficient operation, and careful detachment for
safety.
The role of hydraulics in
operation
Hydraulics play a pivotal role in the operation of tractor 3 point
hitches. Serving as the chief source of power, they allow for the
controlled and efficient movement of the hitch and, consequently, any
attached implement.
At the core of this operation lies the tractor’s hydraulic system,
composed of several elements like pumps, valves, hydraulic fluid,
cylinders, and actuators. When the hydraulic pump is engaged, it
pressures the hydraulic fluid in the system. This pressurized fluid is
then directed towards the cylinders linked to the lower links in the 3
point hitch.
The cylinders react to the hydraulic pressure by expanding or
contracting. This controlled movement adjusts the position of the lower
links, determining how close to or far from the ground the attached
implement will be. Higher hydraulic pressure will cause the hitch to
lift the implement higher off the ground, and diminishing pressure will
enable the implement to lower.
Moreover, the hydraulic system also plays a vital part in the
stabilization of implements. It maintains a steady flow of hydraulic
fluid to the hitch, keeping attached tools steady, even through the
tractor’s uneven movements and sudden stops or accelerations. This
feature is paramount for operators’ safety and optimal function of the
machinery.

Stabilization of attached
implements
Once an implement is attached to a 3 point hitch, its stability is
key to ensuring that it operates effectively and safely. The design of
the 3 point hitch greatly aids stability. The two lower points form a
stable, stationary line. The top point or center link allows for
movements which are essentially up and down. It serves as a guide,
helping the connected implement to follow a consistent path, despite
variations in the terrain.
Stabilizers, attached to the lower links, play a crucial role in
maintaining lateral stability. They prevent sideways movements, ensuring
the implement stays behind the tractor, moving straight forward or
backward, following exactly the tractor’s path. These stabilizers are
often adjustable, allowing tractor operators to decide how much lateral
sway they will allow based on the specific task at hand.
Hydraulic systems further bolster the stability of attached
implements. These systems control the intensity of link lifting or
lowering, which in turn controls the working depth of the implement. By
adjusting the hydraulic pressure, the tractor operator can conveniently
control the height of the implement above the ground, thus improving
precision and stability even on hilly or uneven terrain.
In conclusion, the nature and layout of 3 point hitches essentially
make the tractor and the attached implement function as one unified,
stable entity. This stabilization plays a key role in the operator’s
control over the implement, ultimately contributing to improved results,
whether the task is plowing a field or moving construction
materials.
