I love this tool it is great for handling 21 bale bundles and round bales it is super easy to use and does a great job even with my small 25 hp tractor.
I have an older machine - JD 675B. The center spear hit my attachment and wouldn't let it sit flush to connect the attachment. I had to cut the center one off. I used it with the 2 spears and it worked great. I will ad the third spear to the top center later on.
I'm very happy with the sturdiness of the construction, and the size and strength of this speers. The only problem there is a 5/8 inch gap between my quick connect and the bottom plate. I would recommend it to anyone who needs a good bail spear.
