I too ran (and still do) exmark for many years.
tossed a 48" ferris stander on the trailer a few seasons back.
It's been a great mower, coming up on a thousand hours, and cuts quite well. had some scag super hi-lift blades cut to fit and it throws down some damn nice stripes.
the thing I think that impressed me most, never having a stander before, is all the tricky places I can put it, very nimble machine.
it has a few more grease fittings than some mowers, including spindles, but no biggie.
current trailer setup is 2 48" TT's and the 48" ferris. which is a good combo for my lawns.
