I have a 6x10 trailer with a wooden deck,
but it doesn't have a 3500lb axle,
I think its only 1500 or so.
Anyway the trailer only weighs max 400lbs.
I don't think you have to worry about pulling that mower and trailer.
My dads jeep has a 2000lb towing package and he pulls two skis that weigh 700lbs each and a rather large trailer. His does fine.
I actually think it is the same year as yours. Eitherway, I don't think its a problem.
