I did have a welder, but I still bolted mine on 'cause I thought I might change my mind someday and want them done differently and it would be easy to unbolt them.
I have two mounted on my TC35D on either side at the top of the bucket. They bolt on and can be removed when not needed. They are definitely handy when trying to secure large loads and picking up things. Good Luck /forums/images/graemlins/laugh.gif
