Mild Steel Top Link Pins, Color : Golden for Automotive Industry

Top Link Pin: Overview

A Top Link Pin is a key component used in agricultural and construction machinery to connect the top link (or top arm) of a three-point hitch system to a tractor or implement. The top link pin helps secure the connection and ensures that the implement is correctly attached, allowing for proper movement and functionality during operation.

• Connection Point: The top link pin serves as the attachment point for the top link of a three-point hitch system. It is essential for transferring mechanical power from the tractor to implements like plows, harrows, or cultivators.

• Material: Typically made from high-strength steel or alloy steel to withstand the stresses and loads associated with agricultural or construction tasks. It is often coated for corrosion resistance.

• Size and Fit: Top link pins come in various sizes to fit the specific three-point hitch or implement type. Common diameters include 1 inch, 3/4 inch, and 5/8 inch, but these can vary based on tractor and implement specifications.

1. Agricultural Tractors:

   • The top link pin is used to connect the tractor's three-point hitch to various implements, such as plows, disk harrows, and mowers, for tasks like plowing, tilling, or mowing.

2. Construction Machinery:

   • Used in construction equipment with three-point hitch systems to attach various attachments like backhoes, pallet forks, and grader blades.

3. Utility and Landscape Equipment:

   • In landscaping and utility applications, top link pins help attach dirt graders, lawn aerators, and other machinery to the primary power unit (usually a tractor).

4. Farming Implements:

   • The pin secures the top link of trailers, cultivators, post hole diggers, and other implements, allowing them to be safely used for a wide range of agricultural operations.

• Straight Top Link Pins: Commonly used with implements and tractors, these pins allow for quick attachment and detachment.

• Clevis Top Link Pins: These pins are designed to fit into a clevis (U-shaped coupling) and are typically used in heavy-duty applications where a secure attachment is needed.

• Locking Pins: Some top link pins feature a locking mechanism (e.g., R-clips, cotter pins, or spring-loaded pins) to prevent accidental detachment during use.

The diameter and length of the top link pin are crucial for compatibility with the hitch system and implements. Typical dimensions include:

• Diameter: Common sizes include 1 inch, 3/4 inch, and 5/8 inch.

• Length: Ranges from 3 inches to 6 inches, depending on the size and type of implement.
