Hi Here's a couple of mine, sorry for the clutter but I keep everything warm in the heated shed this time of year. Now this bumper cost about $15.00 to make . A piece of 2 1/2 inch muffler pipe ,1 inch square tubing, round bar, some rock guard paint from Canada tire, about 3 hours in the shop and you get what you want.
The bumper works quite well, I was backing the Rhino off the trailer and crashed into the garage door not a mark on the bumper, the garage, oh well a spring project.
I have a few pic's on the post "Look What brought Home with me" this is NOT mounted to the box, it is mounted to the frame with two pins to remove it any time you need to use the dump box.
