Forged Agri Tractor PTO Shaft

Product: Forged Agri Mower Shaft

What is a steel shaft of mower made?

The steel shaft is typically made from high quality carbon steel or alloy steel. Carbon steel provides good strength and is cost effective. Alloy steel may contain elements such as chromium, nickel, or molybdenum to enhance properties of hardness, toughness, and corrosion resistance. The choice of material and the element control depends on the specific requirements of the mower, such as the load it needs to bear and the operating environment.

How to make steel shaft of mowers?

1️⃣  Forging is a common method for producing the initial shape of the shaft. The steel billet is heated to a suitable temperature and then shaped using a forging press or hammer. This process helps to improve the internal grain structure of the steel, making it stronger and more durable. After forging, the shaft may undergo machining operations. Precision machining is carried out to achieve the exact dimensions required. This includes turning operations to create a smooth cylindrical surface and milling to add keyways or other features for attaching components like pulleys or gears.

2️⃣ Heat treatment is a crucial step to optimize the mechanical properties of the steel shaft. Annealing may be done to relieve internal stresses created during forging or machining. Quenching and tempering are often used to increase the hardness and toughness of the shaft. For example, the shaft can be quenched in a suitable cooling medium (such as oil or water) after being heated to a high temperature, followed by tempering at a lower temperature to reduce brittleness.

3️⃣ Surface Finish: the surface of the shaft may be polished or ground to achieve a smooth finish. This not only improves the aesthetic appearance but also reduces friction when the shaft rotates. In some cases, a coating such as a corrosion - resistant paint or a thin layer of chromium plating may be applied to protect the shaft from rust and wear, especially if the mower is used in humid or corrosive environments.

What function of the shaft in agriculture mowers?

1️⃣ Power Transmission

The steel shaft is a vital component for transmitting power from the tractor's power take - off (PTO) to different parts of the mower. In a mower with a rotary cutting system, for example, the shaft transfers rotational power from the PTO to the cutting blades through a series of pulleys and belts. The shaft's ability to handle high torque and rotational speeds without significant deformation or failure is essential for efficient mowing operations.

2️⃣ Support and Alignment

It provides structural support for other components attached to it. For instance, the cutting blade assemblies are often mounted on the shaft, and the shaft ensures that the blades are properly aligned and spaced. This alignment is critical for achieving an even and consistent cut of the grass or crop. The shaft also helps to maintain the stability of the cutting mechanism, preventing vibrations that could lead to uneven cutting or premature wear of the components.

3️⃣ Load - Bearing Capacity

During mowing, the shaft bears various loads. It has to withstand the weight of the cutting components, as well as the dynamic loads generated during operation. For example, when the mower encounters an obstacle such as a stone or a thick clump of grass, the shaft must be able to handle the sudden increase in load without breaking. Its strength and rigidity ensure that the mower can operate smoothly and reliably under different working conditions.
