1010,
Never seen a roadside mower w/ duels? Got some pics, Many of those operators have frequent underware changes. Ther primary purpose for tractors is twofold: one is visibility and the second is roadspeed so they can get back to the barn to change their shorts.
And dont laugh too hard, wouldn't want to to loose your balance. The OP is not mowing the roadside, CORRECT?
I'll get pics tomorrow at work, duels won't hamper visibility at all, and certainly don't cause reduced speed. Like I said this setup will cut grass on slopes that you can barely walk up.
