The three-point hitch system, often abbreviated as TUZ (Three-Point Hitch System), is commonly used in agricultural tractors. This system allows you to easily connect and disconnect agricultural tools and machinery, while ensuring stability and control over them while working.

Construction of the three-point three-point linkage suspension system:

Lower arms (side arms):

• Two lower arms that are attached to the rear of the tractor and extend to the implement.
• They are adjustable in length and angle, which allows them to be adapted to various tools.

Upper arms (upper connectors):

• One top connector that connects to the tool at a central point.
• Adjustable in length to set the right angle of the implement in relation to the tractor.

Mounting points:

• Each arm (two lower and one upper) has mounting points that fit into corresponding pins on agricultural implements.
• These pins are standard, allowing you to quickly connect and disconnect tools.

Hydraulic lift cylinders:

• Hydraulic cylinders mounted on the lower arms that allow the tool to be raised and lowered.
• Controlled from the tractor cabin, they enable precise adjustment of the implement height.

Features of the three-point three-point hitch system:

Connecting tools:

• It allows easy and quick connection and disconnection of various agricultural tools, such as plows, seeders, cultivators, fertilizer spreaders, etc.

Tool stabilization:

• It ensures the stability of tools during work, minimizing their lateral movements and vibrations.

Tool position adjustment:

• It allows precise adjustment of the height and angle of tools, which is crucial for their effective work.
• Possibility of lifting tools for transport and lowering them during work.

Operation of the three-point three-point hitch system:

Connecting the tool:

• The tool is connected to the lower arms and upper link via pins.
• Make sure all mounting points are well secured.

Arm length adjustment:

• Adjusting the length of the lower arms and upper link to ensure the correct position of the tool.
• Possibility to adjust the angle of attack of the tool relative to the soil.

Raising and lowering the implement:

• Use of hydraulic lift cylinders to raise the implement for transport or lower it during operation.
• Tool height control using the hydraulic system from the tractor cabin.
