I like your design you have for your grapple. I search the web to find a grapple that I could make to use on my skid steer and I liked yours the best of the ones that I have found. I am interested in seeing pictures of your finished product once you have teeth on it.
When I get the grapple finished I will post picture of it. I am in the process of making brackets to mount the arms and hydraulic cylinders. I have the arms made just need the brackets so I can hook them up an see where I need to put the hydralic cylinder. Thanks, Don
