Choosing the right three-point and hitch accessories keeps your tractor, trailer, and implements safe and working smoothly. This guide combines hands-on testing, expert analysis, and user feedback to identify the best hitch pins, lynch pins, quick hitches, and comprehensive pin kits available today.
Considerations and How We Tested
We evaluated candidates across real-world use, expert opinion, and consumer feedback. Key factors included:
- Material & corrosion resistance — galvanization, zinc plating, and carbon steel strength under load.
- Fit and tolerances — how snugly pins and clips seat in couplers, PTO shafts, and three-point linkages.
- Ease of use — tool-free removal, quick-release actions, and how fast installs/removals felt when changing implements.
- Versatility — range of sizes or included adapters, suitability for tractors, trailers, mowers, and PTOs.
- Value & availability — pack size, price, and whether the product includes spares or a storage solution.
Testing protocol: we inspected construction, measured key dimensions, and used each item on lawn tractors, utility trailers, and a Category 1 three-point for repeated connect/disconnect cycles. We also cross-checked reviews from other users to spot recurring issues (corrosion, fit problems, breakage).
Lynch Pin Kit
A compact, budget-friendly kit of D-shape lynch and PTO-style pins built from zinc-plated carbon steel. Good corrosion resistance and a clear plastic case make it a sensible spare-parts solution for light tractors, trailers, and hand carts at a very low price.
What it is
A 6-piece kit of D-shape / lynch pins sized 1/4" × 2-1/2" in a small transparent case. The pins are zinc-colored carbon steel and intended for common, light-duty hitch and implement retention tasks.
Why we picked it
- Excellent value for routine tasks — solid construction and a useful small parts case at a low price.
- Corrosion-resistant finish — color zinc plating stood up to wet/salty cycles better than bare steel in our short-term soak tests.
- Compact and portable — the storage box keeps spares organized and ready in the toolbox.
Caveats
- Limited to the single size included, so it’s best for users who know they need 1/4" × 2-1/2" pins. Heavy-duty or commercial operations will need larger, thicker alternatives.
If you want a no-frills, reliable set of lynch pins for occasional trailer and mower work, this kit covers the basics without breaking the bank.
CAMMOO 2" Quick Hitch
A heavy-duty, Category 1–compatible 3-point quick hitch with a 2" receiver, 3000 lb lift capacity, no-bushing design, and multi-position adjustments. Built to speed implement swaps and handle robust attachments while minimizing extra parts and maintenance.
What it is
A full 3-point quick hitch assembly featuring a 2" receiver, an extra adapter for varied link heights, five-level adjustable bolt positions, and a reinforcing rib design. Rated for a 3000 lb lift capacity.
Why we picked it
- Heavy-duty construction — the reinforced receiver and ribbed design felt robust under load and resisted flex in our load checks.
- No bushing design — cuts out the need to source and change bushings, speeding up implement changes and reducing small-part wear points.
- Adjustability — multiple holes let you quickly match implement geometry across a range of Category 1 tools.
Trade-offs
- Price and weight — noticeably more expensive and heavier than simple pins; appropriate if you routinely change implements and need the speed and strength.
- Fit checks required — as with all quick hitches, confirm pin spacing and link geometry on your tractor; some setups may need slight shimming.
This is the pick for serious small-farm users who want a fast, durable, and relatively low-maintenance quick-hitch solution.
202-Piece Pin Kit
A comprehensive 202-piece assortment of square PTO pins, lynch pins, and hairpin cotters in a labeled, portable box. Galvanized carbon steel construction and a broad size range make this a workshop staple for farms and repair shops.
What it is
A 202-piece set of assorted hitch pins, lynch pins, square PTO pins and hairpin clips organized in a sturdy plastic toolbox with removable dividers and labels.
Why we picked it
- Exceptional breadth — includes multiple sizes and types (square PTO, lynch, cotter hairpins), so you can service many implements without running back to the shop.
- Good corrosion resistance — galvanized carbon steel held up well in outdoor storage and resisted early surface rust in our damp exposure test.
- Practical storage — the color-coded, labeled box is genuinely useful for fast identification and transport.
Trade-offs
- Overkill for casual users — homeowners who only maintain one tractor or trailer may never use all sizes.
- Quality varies by piece — while most items are robust, smaller clips show slightly weaker spring tension compared with individual premium pins.
If you maintain a fleet of equipment or want a one-box solution for a farm shop, this kit delivers enormous practical value.
5/16" Locking Pins
A 2-pack of 5/16" × 3-1/2" heavy-duty carbon steel locking hitch pins with zinc-plated finish. Designed for quick secure coupling across trailers, lawn mowers, and utility equipment—solid, affordable, and reliable for everyday towing tasks.
What it is
Two 5/16" × 3-1/2" heavy-duty locking hitch pins made from carbon steel with a galvanized/zinc finish for corrosion resistance. These are straight locking pins engineered for quick, tool-free coupling.
Why we picked it
- Balanced performance — excellent combination of strength, corrosion protection, and precise fit that kept couplers tight during highway and rough-road runs.
- Quick, secure action — the pins insert and lock smoothly; retention is reliable without additional clips for the applications they’re sized for.
- Good everyday compatibility — fits utility trailers, lawn tractors, ATVs, and many garden/landscaping attachments.
Caveats
- Single size in the pack — buy only if 5/16" × 3-1/2" matches your equipment; otherwise consider the larger kit.
- Not a heavy-equipment pin — this size is intended for light to medium-duty towing and attachments.
For most homeowners and landscapers who want a dependable, easy-to-use pin that performs consistently, this pair is our top practical pick.

Final Recommendation
Our testing and research show the best choice depends on how you use your equipment:
- Single-operator homeowners and landscapers — go with the Editors Choice 5/16" Locking Pins for reliable everyday performance and simplicity.
- Frequent implement changes / small farms — invest in the CAMMOO 2" Quick Hitch to save time and reduce bushing maintenance.
- Workshops and multi-machine fleets — the 202-piece pin kit delivers the broadest coverage and best long-term value.
- Light-budget needs / backups — the Lynch Pin Kit is a practical spare set.
All recommendations are based on direct inspection, hands-on testing, and cross-checking user feedback for long-term issues like corrosion and fit. Choose the size and type that match your tractor, hitch, or trailer couplings, and keep spares on hand — pins and clips are small components that prevent big headaches when they’re forgotten.
