6 Best Linch Pin Brands for Farm Equipment

You hear the clank and then a sickening scrape of metal on gravel, and your heart sinks. You look back to see your box blade sitting twenty yards behind the tractor, disconnected and useless. A five-dollar part just failed, costing you an hour of your precious weekend and potentially damaging a thousand-dollar implement.

Why a Simple Linch Pin is Critical on the Farm

A linch pin is the humble hero of the three-point hitch. It’s the small, self-locking pin that secures your implements to the lift arms of your tractor. Without it, nothing stays connected. It’s easy to overlook this little piece of hardware until one breaks, gets lost in the tall grass, or simply wears out.

The consequences of a pin failure aren’t just inconvenient. A dropped implement can dig into your driveway, damage your field, or worse, break a hydraulic line or PTO shaft. In a worst-case scenario on a slope, it can create a serious safety hazard.

That’s why experienced farmers don’t just grab any old pin from the bucket of bolts. They know that a quality pin provides peace of mind. Investing in a good brand is cheap insurance against expensive failures. It’s about reliability, not just holding things together.

SpeeCo: The Reliable Standard for General Use

When you walk into almost any farm supply store, you’ll find a bin full of SpeeCo pins. There’s a good reason for that. They are the consistent, reliable workhorse for everyday tasks around the farm.

SpeeCo pins have a solid feel, a dependable locking ring, and a finish that holds up to a season or two of use before showing its age. They aren’t the fanciest or the strongest, but they hit the sweet spot of quality and affordability. For connecting a landscape rake, a light-duty mower, or a carry-all, a SpeeCo pin is more than enough for the job.

Think of SpeeCo as the default choice. If you’re not sure what you need, starting here is never a bad decision. They are predictable and trustworthy, which is exactly what you want from a part that works out of sight and out of mind.

Buyers Products: Heavy-Duty Pins for Big Implements

Some jobs demand more than the standard. When you’re hooking up a heavy subsoiler, a loaded-down box blade, or a big rotary cutter, the shear forces and constant vibration are on another level. This is where Buyers Products shines.

Known for their truck and trailer equipment, Buyers brings a heavy-duty manufacturing mindset to their farm hardware. Their linch pins are often visibly beefier, with thicker steel and oversized, stronger rings that are easier to handle with gloves on. The plating seems to last longer, resisting rust even after being scraped and dinged.

You pay a little more for a Buyers pin, but the cost is negligible when you consider the equipment it’s securing. Use them on your heaviest, most demanding implements. It’s the right tool for the job when the forces involved could bend or shear a lesser pin.

The Hillman Group: Accessible and Dependable Pins

Sometimes you’re not at the farm co-op. You’re at the local hardware store grabbing something else and remember you need a spare pin. That’s where you’ll find The Hillman Group, and they are a perfectly dependable option.

Hillman is a giant in the fastener world, and their quality control is excellent. Their pins might not be specifically marketed to farmers, but they are made to industrial standards. They offer a clean finish, a snappy ring, and precise sizing that fits implements without excessive slop.

Don’t mistake their availability in a big-box store for lower quality. A Hillman pin will reliably secure your post-hole digger or fertilizer spreader without issue. They are a fantastic, widely available choice for keeping your workshop stocked with spares you can trust.

A&I Products: OEM-Quality Aftermarket Options

If you’ve ever priced a simple part like a pin from an equipment dealer, you know the sticker shock is real. A&I Products exists to solve that problem. They specialize in creating aftermarket parts that meet or exceed the Original Equipment Manufacturer (OEM) specifications.

This means an A&I pin is engineered to be a direct, high-quality replacement for the one that came with your John Deere, Kubota, or Massey Ferguson tractor. They focus on getting the details right—the exact length, diameter, and material strength the original engineers called for. This is crucial for implements where a sloppy fit could cause excessive wear on the hitch points.

Choose A&I when you want dealer-level quality without the dealer-level price. They are the smart choice for replacing a lost pin on a newer, expensive piece of equipment where maintaining a perfect fit is a priority.

Forney Industries: Tough Pins from a Welding Name

Forney is a name synonymous with welding—a world of high heat, immense stress, and tough metal. They bring that same reputation for durability to their hardware, including their linch pins. These pins are built to be abused.

A Forney pin feels substantial in your hand. The steel is high-quality, and the construction is geared toward strength. This makes them an excellent choice for custom-fabricated implements or for high-stress connections that see a lot of jarring and twisting motion.

If you have an old, heavy-duty brush hog that rattles every bolt loose or a homemade attachment that puts unusual stress on its connection points, a Forney pin provides an extra margin of safety. They are built with a welder’s understanding of what it takes for metal to hold up under pressure.

Agri-Supply House Brand: Unbeatable Value Pins

Every workshop needs a coffee can full of spare pins. For filling that can, you can’t beat the value of the house brand from a place like Agri-Supply. They offer bulk packs of pins for a price that makes them practically disposable.

Let’s be clear about the tradeoff. The finish might not be as durable, and the tolerances might not be as tight as a premium brand. The ring might feel a little less robust. But for light-duty tasks or for implements you only use a few times a year, they are perfectly adequate.

The real advantage is having plenty of spares. When you inevitably lose a pin in the field, you won’t think twice about grabbing a new one. Having a good-enough pin on hand is always better than having no pin at all. They are the definition of practical, affordable hardware.

Choosing the Right Pin: Zinc vs. Stainless Steel

Beyond the brand, the material your pin is made from matters. The choice almost always comes down to zinc-plated steel or stainless steel, and each has a clear purpose.

Zinc-plated steel is the industry standard for a reason. The zinc coating provides a solid layer of corrosion resistance that is perfectly fine for most farm conditions. It’s affordable and effective. For 90% of your implements that are stored in a barn or shed, a zinc-plated pin is all you need.

Stainless steel is the premium option for specific, harsh environments.

• Constant Moisture: If an implement lives outside year-round, stainless steel won’t rust and seize up.
• Corrosive Materials: For a manure spreader or a 3-point salt spreader for the driveway, stainless is a must. Salt and chemicals will eat through a zinc coating in no time.
• Peace of Mind: A stainless pin will still be easy to remove after years of neglect.

The choice is simple. Use zinc for general purposes and invest in stainless for any implement that is constantly exposed to moisture or corrosive materials. The extra cost upfront will save you from fighting a rusted pin with a hammer and penetrating oil later.

Ultimately, the best brand of linch pin is the one you have in your toolbox when you need it. Don’t overthink it for most jobs, but don’t underestimate the importance of this small part. Stock up on a few good ones, use a heavy-duty pin where it counts, and you’ll spend more time working and less time fixing.
