I did my first winter equipment demo last week over at the Greywalls shop.
I tested a Toro GroundsMaster 7210 with the Polar Trac attachment system, it also had an out front snow blower.  This unit is a zero turn mower that can come with a full articulating 100" front deck for summer use and then provide additional value as the trac and heated cab are added for winter use.  Multiple front attachments are available from the snow blower to a V-plow to a rotary brush and of course the mowing deck.
I was really impressed with the snow blower, it launches some serious snow.  If we ever get into winter recreation at the club this could be a valuable unit to pull a small groomer with.
Great demo, I was impressed.
