I have a 48" belt wb and 60" clear space between the steel on my open trailer. Keeping this mower close to the center going up the gate to reload is no problem except if it is wet. But even then, 6" clearance per side is plenty. I am considering a 54" hydro that will be close to 56" wide with the chute up. That only leaves 2" clearance on each side of the mower when reloading. As you might guess, I would rather not buy a wider trailer to go with the bigger mower. I am thinking that a hydro will be much more precise to control, and not need near as much clearance as a belt drive. But I have no experience with hydro's and can't put a number on it. I would like the opinions of lco's who have hdyro wb's as to the minumum width of an open trailer they would use for a 54" hydro. Thanks.
