Re: B7500 w/ MMM and 16\' trailer.....
Don.
On most 16' double-axle trailers the usable floor widths are usually in the 6'4" - 6'7" range and are plenty WIDE enough to handle a 60" mid-mower.
But I do have a personal experience story about B7500s that may be educational for you...
I have a 16' trailer with separate ramps (about 4' long) that sit in a grove at the rear of the trailer when in use. On level ground the front edge of these ramps protrude almost 2" above the height of the floor of the trailer. Once, when un-loading my friend's
B7500 with mid-mower, the edge of the mower caught this "lip" of the ramps unexpectedly. At the time I had a smaller
B7100 with 48" mid-mower, but I never had a problem with this tractor because the 48" mower had a skid plate design along the outer edges of the mower that prevented this from happening. I can easily load and unload the
B7500 when I perform the loading/unloading operation into terrain with a slight uphill slope, or have the trailer attached to a vehicle with a high mounted trailer hitch (thus lowering the rear of the trailer).
Bottom line: Some trailers will work fine, some will not. For trailer that you are considering, pay careful attention to how far the ramp protrudes above the floor of the trailer. Hopefully, you will be able to perform a "practice" loading operation of your
B7500 with the trailer you are intending to purchase
when attached to your intended tow vehicle.
