I built my boom pole out of 2"x4"x1/4" square tube, works fantastic with a 300lb weightbox on the front. I use it for logs/rounds and moving thd front mount blower around after taking it off for the season.

If the OP were closer I’d give him my boom pole for free. The only time I used it, it lifted the front wheels off the ground trying to pull a post out of the ground.
