Description
If you’ve ever been hooking up to a PTO-driven implement and found yourself wrestling with a bent or worn-out lock pin that just won’t slide through cleanly, you know how frustrating it can be. This 5/16 inch square wire lock pin gives you that clean, secure connection every time, whether you’re attaching a rotary cutter, hay baler, or any other PTO equipment that needs to stay put while you work.
What You’re Getting
- 5/16 inch diameter pin with 2-1/4 inch usable length fits most standard PTO applications
- Square wire design resists bending better than round wire pins, especially under vibration
- Spring-loaded mechanism keeps the pin securely locked in place until you need to remove it
- Durable construction that holds up to the constant connecting and disconnecting of farm work
Built for Real Farm Work
This pin works with a wide range of PTO-driven equipment across all tractor brands. Whether you’re running a finish mower on your compact utility tractor or powering a heavy-duty rotary cutter behind a larger machine, having a reliable lock pin means one less thing to worry about when you’re focused on getting the job done right.
Made to Last
The square wire design gives this pin an edge over traditional round wire versions – it’s less likely to bend or deform when you’re working in tight spaces or dealing with equipment that’s seen better days. The spring mechanism stays responsive even after countless uses, and the overall construction handles the vibration and stress of PTO operations without failing.
Good to Know
Keep a spare or two in your toolbox – these pins have a way of walking off when you need them most. The square wire makes this pin slightly stiffer than round wire versions, which some folks prefer for the extra security, though it might take a tiny bit more effort to compress the spring when installing.
