Works perfectly. Now we can lower the handle easily without having to unscrew bolts every time ### ⭐⭐⭐⭐⭐ Better than OEM *by J***Z on September 14, 2023* I have an Earthquate Versa rototiller that uses hitches like these to attach the tines and to fasten the drag stake into position. When I recently tried to use the tiller, I noticed that the hitch for the drag stake had come apart - the top of the pin was fastened to the loop with what looked like a paper clip, and the "clip" had come undone so the pin was lost. I purchased these pins, and was pleased to note that the pin was fastened with a fully welded loop, so it won't come loose. The size is perfect, and the hitch stays firmly in place while the machine is in use. I'm glad that I now have hitch pins to spare, since the garden is destined to be expanded next year! ## Frequently Bought Together - INCREWAY 4PCS Wire Lock Pin, 5/16" Carbon Steel Shaft Locking Pin Safety Coupler Pin Round Loop Wire Lock Trailers Pin for Farm Lawn Garden - INCREWAY 10pcs Wire Lock Pin, 1/4" Heavy Duty Safety Coupler Shaft Locking Pin Hitch Pto Pin Round Loop Wire Lock Trailers Pin for Farm Lawn Garden - Highwild 8 Pack Silent Shaft Locking Pin with Spring - for Farm Lawn Garden - Hunting Stand Ladder Stands Safety --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.th/products/405807634-4pcs-wire-lock-pin-5-16-carbon-steel-shaft-locking](https://www.desertcart.co.th/products/405807634-4pcs-wire-lock-pin-5-16-carbon-steel-shaft-locking) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-04-30*
