Yep, you'll have reverse as well as a high and low range. Most of the time hill descent = engine brake, so you would be correct. Mine will "freewheel", just like a snowmobile does when the clutch isn't engaged. When I'm going down a steepish hill in high range I tap the gas to keep the clutch engaged which then acts like a engine brake. If I'm in low range it's a non-issue. I wouldn't let a machine having or not having hill descent be the deciding factor for a purchase. Tapping the gas will accomplish the same thing. IMO.
