I run a 6.5X12 open trailer some and have a 48" Gravely WB as well as a 60" Lazer. I run the lazer to the front and then turn the WB sideways on the back. It's tight, but it'll work. You will probably have to step up on the side rail to completely turn it sideways, there is not enough room for you and the mower sideways. I am almost finished with my 16ft. tandem with a 52" side gate at the front. I can't wait. I'll post pics later when I'm done with it.
