Pins are the cheapest part on a tractor and the one that stops the machine when it fails. That is why hitch pins, linch pins and clevis pins sit on nearly every reorder list — and why US dealers, implement shops and distributors keep asking the same question: how do I identify the right pin, and where do I buy it in volume at a fair price?
Jrs Farm Parts is an ISO 9001:2015-certified manufacturer and exporter based in Ludhiana, Punjab, India, exporting linkage and implement hardware to the USA and 60+ countries. We are an Indian manufacturer-exporter — we do not manufacture in the United States — and this guide covers how pins are specified, what buyers mean by the common style names, and how to order direct from the factory.
The Three Pins Buyers Usually Mean
Hitch Pins
A hitch pin holds a drawbar, implement or linkage arm in place. It is the workhorse of implement connection hardware. When US buyers search “hitch pin,” they are usually looking for a pin with a head at one end and a drilled hole or clip at the other to stop it working loose.
Linch Pins
A linch pin is a two-piece retention pin: a shaft with a hinged or spring loop that drops into place and locks the pin against vibration. It is the standard choice where a pin must be removed and refitted often, and it is what most implement operators picture when they talk about a “lynch pin.”
Clevis Pins
A clevis pin is a plain, head-on-one-end pin that takes a separate clip, cotter or R-clip. Clevis pins and hitch pins are often used interchangeably in conversation, but the retention method — and therefore the correct replacement — differs.
A note on terminology: spelling varies in the market (“lin ch pin,” “lynch pin,” “lin chpin”). This guide covers the same part family regardless of how it is spelled. What identifies a pin is not its name but its shaft diameter, usable length and retention style.
How Pins Are Specified — The Measurements That Actually Matter
Pin catalogues are built on dimensions, not names. To identify a replacement pin correctly, four figures are needed:
- Shaft diameter — the diameter of the pin body that passes through the hole.
- Usable length — the length from under the head (or loop) to the retaining hole, i.e. the distance that actually spans the parts being joined.
- Head or loop style — plain head, T-handle, wire loop, or spring/hinged loop for linch pins.
- Retention method — drilled hole with a clip, cotter pin, R-clip, or the linch pin’s own spring loop.
How to measure a pin you already have: measure the shaft with a caliper (not a tape), measure usable length with the pin seated in its hole, and check whether the retaining hole is drilled or the loop is fixed. Sending those three figures is usually enough for us to confirm a match.
Why we don’t publish a one-size-fits-all chart: pin dimensions vary by implement and by manufacturer, and a nominal size label does not guarantee a fit. We confirm dimensions against your measurement or part number before an order is accepted — we do not ask buyers to guess from a table.
Pin Styles Buyers Commonly Ask For
Red Handle Hitch Pins
“Red handle” is a buyer’s shorthand for a hitch pin with a coloured, typically coated handle that is easy to spot in crop or grass and easy to grip with gloves. It describes the handle style, not a different pin — the shaft dimensions and retention method are what determine whether a pin fits. If you are matching an existing part, send the shaft diameter, usable length and a photo of the handle style, and we will confirm what we can supply.
Plain Head / Standard Hitch Pins
The conventional pin format, generally retained by a clip or cotter through a drilled hole.
Linch Pins with Spring Loop
The retention element is built into the pin, which speeds up attachment changes in the field.
Clevis Pins and Clips
Plain pins sold alongside the clip or cotter that retains them, commonly ordered together as a pin-and-clip set.
Styles, handle colours, coatings and packaging are confirmed per order and per market — availability is quoted, not assumed.
Where These Pins Are Used
- 3-point linkage — top link and lower link connection and stabilizer hardware (see the 3 point linkage parts hub)
- Drawbars and implement hitches — see the drawbars category
- Trailer and tow couplings — see the trailer parts category
- Tillage and harvest implements — see the harrow discs and tillage parts guide
Pins are a natural consolidation item: they ship in the same export crates as linkage and trailer parts, so dealers can add them to a larger order instead of sourcing them separately.
Buying Pins Direct From the Manufacturer
- Quotes: send your pin list with measurements (shaft diameter, usable length, head/loop style) or part numbers via the quote form; we reply within 1-2 business days.
- Minimums (MOQ): vary by pin style and finish — standard pins order in bulk wholesale quantities; custom or coloured-handle runs require higher minimums.
- Payment: Letter of Credit (L/C) or Wire Transfer (T/T).
- Production: approximately 40 days for standard and repeat items.
- Shipping: pins ship in wooden export crates from Mundra or Nhava Sheva (Mumbai) by sea; for US buyers we ship to East and West Coast ports. Ask for the current routing.
- US customs documentation: commercial invoice, packing list, certificate of origin (COO) and HS codes. As a US importer you are the Importer of Record — customs entry, duty payment and the Importer Security Filing (ISF, “10+2”) are handled by your customs broker or freight forwarder. We supply the required documentation.
- Trade status: goods manufactured in India do not qualify for USMCA preference; standard US duty rates apply. Confirm the applicable rate with your broker — we do not give duty or tariff advice.
Frequently Asked Questions (FAQ)
Do you manufacture and export tractor hitch pins and linch pins to the USA?
Yes. We manufacture hitch pins, linch pins, clevis pins and related implement hardware at our ISO 9001:2015-certified plant in India and export to the USA and 60+ countries. Send your pin list with measurements or part numbers for a quote.
Are your pins made in the United States?
No. Jrs Farm Parts is a manufacturer and exporter based in Ludhiana, Punjab, India. Our products are manufactured in our ISO-certified plant in India and exported to the USA and 60+ countries. We do not manufacture in the United States.
How do I find the right pin size for my tractor or implement?
Measure the shaft diameter with a caliper, measure the usable length with the pin seated in its hole, and note the head or loop style and how the pin is retained (clip, cotter, R-clip or built-in spring loop). Send those figures to us and we will confirm whether we can match the pin.
Do you supply red handle hitch pins?
“Red handle” refers to a handle style rather than a size. Send the shaft diameter, usable length and a photo of the existing pin and we will confirm what we can supply and in what finish. We do not publish a stand-alone red-handle catalogue because the shaft dimensions — not the colour — determine the fit.
Why don’t you publish a linch pin size chart?
Because a nominal size label does not guarantee a fit across different implements and manufacturers. Once we have confirmed and verified a dimensional range for our pin lines, we will publish it on this page as a reference — until then we confirm each pin against your measurement or part number rather than risk sending the wrong part.
What are your minimums and lead times for pin orders?
Minimum order quantities vary by pin style and finish. Production runs approximately 40 days for standard and repeat items, plus ocean transit to your US port. Ask our team for MOQ and routing for the specific pin you need.
