Three-point linkage / CAT I / Kubota / Iseki TX

The TUZ is a connection between a tractor and an agricultural machine and is a special arrangement of elements, thanks to which it is possible to lift, transport and set the appropriate position in relation to the ground and the tractor, agricultural machines and devices. Hydraulically controlled three-point suspension system (abbreviated TUZ) as the name suggests, is a connection of an agricultural machine with a tractor at three points, i.e. on two hydraulically lifted beams connected to blades with a so-called tie rod (right left side) and a centrally located connector, a so-called turnbuckle. What is the TUZ of a tractor for?:

• for lifting and transporting agricultural machines and equipment,
• to determine the appropriate working depth or height of an agricultural machine or device,
• for transporting machines and equipment,
• to stabilize machines and equipment during transport.

How does a tractor’s three-point linkage work?

The hydraulically operated rear linkage consists of a cylinder, pump, safety valve and hydraulic distributor. The operation of the linkage system is directly responsible for the hydraulic oil flowing through the system under pressure, controlled and operated by the cylinder and hydraulic distributor. The hydraulic cylinder (single or double-acting) is responsible for lifting the system (and lowering the double-acting cylinder), the hydraulic pump for generating the appropriate pressure in the system, the safety valve is a fuse that reduces the pressure in the system after exceeding the maximum possible lifting capacity, and the hydraulic distributor is a device controlling the flow of oil in the system. The operation of the linkage lift is directly responsible for the hydraulic oil flowing through the system under pressure, controlled and operated by the cylinder and hydraulic distributor.

The TUZ Cat I suspension set is designed for Kubota and Iseki tractors and mines and consists of :

• lower arms x 2 (lases),
• upper connector (turnbuckle),
• hangers (connecting the lower arms of the lift with the upper ones, the so-called lifting arms) x 2,
• chains pulling lower arms x 2,
• lower arm mounting bracket,
• turnbuckle bracket,
• trailer drawbar.

The lower arms of the TUZ most often have a ball end, but in modern systems manufacturers use more universal hook ends. The three-point TUZ suspension system can be used both at the rear and at the front of the tractor. TUZ suspensions differ in the length of the lower arms, the diameter of the ball holes and the length of the hangers and before buying, you should carefully measure the distance from the lower arm mounting pins to the appropriate distance behind the tractor tire.
