What It Is

The mankk 50PCS Heavy Duty Lynch Pin Assortment Kit is a bulk set of steel linch pins (also called hitch pins or ring clips) used to secure attachments on tractors, trailers, trucks, and lawn mowers. It’s designed for quick, tool-free attachment of PTO shafts, mower decks, tow-behind equipment, and other pinned connections.

Fitment & Compatibility

• Pin diameters: 3/16", 1/4", 5/16", 3/8", 7/16", and 1/2" – measure your existing pin holes with a caliper or ruler before ordering. Most lawn mower deck pins use 3/16" or 1/4"; tractor PTO shafts often use 5/16" or 3/8".
• Pin lengths: Vary by size (typically 1.5" to 3") – ensure the pin is long enough to pass through your attachment and still allow the ring clip to lock.
• Ring clip style: Standard hairpin-style clips – not locking or cotter pins. Confirm your equipment uses this type (common on lawn tractors, zero-turns, and small farm implements).
• Does not replace: OEM-specific pins with unique shapes, shoulder bolts, or quick-release mechanisms. Check if your mower deck uses a specialty pin (e.g., John Deere’s threaded or snap-lock pins).
• Material: Zinc-plated steel – fine for occasional outdoor use, but not rust-proof for salt or wet environments.

Key Things to Know

• No installation difficulty: Just push through the hole and snap the ring clip over the pin’s groove. No tools needed.
• Durability: Rated as heavy-duty, but the zinc coating can chip or rust over time if left in rain/snow. Consider stainless steel for coastal or high-moisture areas.
• Common gotcha: The ring clips can loosen or pop off under heavy vibration (e.g., rough terrain). Double-check fitment and carry spares.
• Bulk value: 50 pins for $23 is cheaper than buying individually at hardware stores, but you’ll have many sizes you may never use.

Should You Buy It

Buy this kit if you own multiple small tractors, mowers, or trailers and want a one-size-fits-most stash of basic linch pins for non-critical attachments. Skip it if you need a specific size for a high-vibration PTO connection, a rust-resistant option, or an OEM-replacement shape for a modern mower deck.
