Lift arm pins by Monroe

While small in size, lift arm pins play an important role in many agricultural and industrial machines. They connect to the lift arms of a machine, such as a tractor. Once connected, lift arm pins allow articulation of the lift arms. For a better understanding of lift arm pins and how they work, keep reading.

Overview of Lift Arm Pins

Lift arm pins are removable fasteners that are designed for use with the lift arms of a machine. They are commonly found on tractors. Tractors have lift arms that are part of a three-point hitch. The three-point hitch consists of an upper arm and two lower lift arms. While the upper arm is typically moveable, only the lower arms are powered by hydraulics.

With this three-point hitch with an upper arm and two lower arms, tractors can carry and utilize accessories. Lift arm pins facilitate the use of accessories. They connect to the lift arms while subsequently allowing tractors to carry and use accessories.

Common tractor accessories that use lift arm pins include the following:

  • Buckets
  • Grader blades
  • Mulching blades
  • Forks

How Lift Arm Pins Work

There are different types of lift arm pins, each of which works in a different way. Most lift arm pins, however, use a similar method to connect the lift arms of the tractor or machinery with which they are used.

You can use a lift arm by aligning it with the appropriate hole in the lift arm. Lift arms are typically built with holes designed specifically for lift arms. Inserting a lift arm pin through this hole and into the tractor or machinery will hold it in place. Depending on the particular type of lift arm pin, you may need to use an additional attachment as well, such as a retaining clip or cotter pin.

What to Look for in a Lift Arm Pin

You should choose a lift arm pin made of a strong material. After all, it will be responsible for holding a lift arm. If the pin fails, the lift arm may fall off the tractor or machinery.

Lift arm pins are available in a variety of strong materials. Some of them are made of hardened steel, whereas others are made of reinforced alloys. Whether hardened steel or reinforced alloy, though, you can rest assured knowing that they will last.

You should choose a lift arm pin the right size. Lift arm pins aren’t universal. You can find them in different sizes, with some pins being longer or wider than others. Regardless, you’ll need to choose a lift arm pin in a size that’s compatible with the lift arm.

In Conclusion

Lift arm pins are removable fasteners that are used to attach lift arms. They connect lift arms to tractors so that tractors can carry and use accessories.
