This year I only have one mower, Ferris 48'' w/b. But next year I am going to be adding a Ferris ZTR, probably one of the bigger ones. What I was wondering is what size trailer should I get. I don't want to get a 10 ft. now and then have to upgrade when I get a new mower. How big do I need a trailor to fit a w/b and a ZTR? I don't want to get a trailer that is too small and need to upgrade so what size trailer will I need to fit both these machines, and what are you guys running?
