AWD that exceeds all expectations

I have a steep lawn : 30 degrees in most places and fortunately a few short places 45 degrees steep. This mower goes up everywhere easily ( but I cannot climb with it very far on the 45 degree parts) . It starts easily. It changes from 2 wheel to 4 wheel drive so smoothly you cannot feel it ( except that it can climb any hill that I have ) . The personal pace is just as smooth. Does not need a fuel bulb to push before starting. No controls. Just pull the start rope ( usually only once ) and go. I have another Toro lawn mower at my other property which is 24 years old and working still well . I bought it 24 years ago because at that time my neighbor had a 10 year old Toro mower which had never let him down. Toro seems hold up to the test of time in terms function , dependability and places where they can be repaired ( I have never needed a repair ).
