I've owned and operated my Ferris 1000Z for 3 yrs out here on the farm. It is absolutely my most prized possession. Right after the tractor. My Ferris, however, gets more seat time.
Debris? My wife calls it being Ferris'd.
You can try a less lift blade set up.
You can place a baffle on your discharge to mulch your clippings.
You can even put a grass bagger/vacuum system on your Z.
However, your best friend is a faster forward speed.
To be somewhere else when the discharge exits the deck is your goal.
Keeping this in mind, I submit that you can look for a machine that discharges to the rear of you deck.
How about making turns with your Z only to the trim side of the deck? In doing so, you are discharging debris to the right and turning left "away from" and not "into" the airborne clippings and dust.
Sometimes problems are more logistical, as opposed to mechanical, no? You'll still come in and have the wife tell you to leave the predominance of your attire in the garage. It's just the nature of the business.
I have an equine facility and, invariably when I drag the various paddocks with a chain harrow to break up the clumps of dobbin's muffins you're just gonna get a little of the airborne "material" in places that the sun never, ever shines.
I actually have a wardrobe set aside for Ferris-ing. There's a certain section of my dresser drawer set aside for various shades of off white, to light green or even light brown socks to underwear(No skid mark jokes, please).
How'd we get off onto this subject, anyway?
Excuse me while I take a moment to clear my nasal passage of foreign material. Wipe some green stuff from the corner of my eye and rinse down the shower.
"Hey, who washed the dog in my bathroom?"
