### ⭐⭐⭐⭐⭐ The measurements are accurate
*by T***N on November 7, 2025*

### ⭐⭐⭐⭐⭐ Works great for Wonderfold W4
*by E***Y on August 27, 2025*

Purchased to replace the handlebar bolts for the Wonderfold W4. 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!
