Actually the tractor and bucket were bought new. The bucket gets up close and personal with a lot of rock. :laughing:
I was thinking they might be for grapples but as CDN Farm Boy said there would need to be some place to attach the cylinder.
My other thought was for mounting directly to loader arms instead of with the SSQA mount but, again, there would need to be more sets of ears.
Just one of those things I've always wondered about since I bought it.
