STARK Relax U-Plow, H-model
Heavy duty operating efficiency
The largest model of the STARK RELAX U-Plow is the most efficient and versatile U-Plow on the market. Its advantage over competitors is based not only on durability, but also on excellent snow management. The U-Plow can collect, move and pack snow into banks most efficiently.
The wings of the H-models are 1,35 m high, the middle wings are 2,4 m or 3,0 m wide and the total width of the plow varies from 4,2 to 6,6 meters. The H-models are suitable for machines weighing more than 10 tons.
Robust construction and practical features:
- Smoothness and safety: The RELAX blade system ensures a smooth plowing pattern and reduces the amount of packed snow. The blade release mechanism protects the driver, the basic machine and the attachment from damage.
- High-quality work result: The FLOATING FRAME floating system follows the ground surface precisely and reduces the plow bouncing.
- Good controllability: The SMOOTH MOTION side wing swivel system enables controlled plowing and a wide range of motion of the wings.
- Versatility: Thanks to various hydraulic options, steering is more efficient and user comfort is improved.

Technologies
RELAX – UNIQUE PATENTED BLADE SYSTEM
The RELAX blade system keeps the plow blades locked. The plow´s trace is smooth and the formation of the packed snow is considerably less.
When the blade strikes an obstacle, the blade system lock is released, the blade body turns backwards and the blade passes over the obstacle. This protects the driver, implement and base machine from collision damage.
The plow with the RELAX blade system can be pressed against the plowed surface, which allows removal of the packed snow.
How the RELAX blade system works:
- The blade body is mechanically locked by three joints (Figure 1.).
- As the load increases, the lock is released and the blade body makes a rapid and extensive evasive movement (Figure 2.).
- When the load is released, the spring returns the blade body back to the lock (Figure 1.).
- The blade release force can be infinitely adjusted by changing the angle of the joints (Figure 3.).
The greater the angle between the joints (Figure 1.), the lighter the lock will open. WHEN TIGHTENING THE NUT the release force DECREASES, WHEN LOOSENING THE NUT the release force INCREASES (Figure 3.).
SMOOTH MOTION -WING TURNING SYSTEM
Patented SMOOTH MOTION wing turning system with two hydraulic cylinders for extremely precise, controlled and wide range of U-plow´s side wings motion. The plow is easy to use and has an excellent work result.
The speed of movement of the side wings and the force of motion are constant throughout the course of motion, without any sudden changes. Easy manageability increases efficiency and security. Wide range of motion facilitates snow collection, stacking and narrow plowing (Figures 1, 2, 3).
FLOATING FRAME
FLOATING FRAME -technology gives you a very good working result.
The float closely follows the ground, the sliding plates and the positioning of the float reduce the bouncing of the unit during work. The implement can float vertically and horizontally (Figure 1.) without the implement being controlled by the base machine.
The float is positioned at the implement mount, which also allows the payload of the swivel frame and a good focus on the implement (Figure 2.). The sliding plates are maintenance-free (no lubrication required) and dampen plow bounce (Figure 3.).
Applicability
