All was as expected: the sales rep was a joy to work with.
My lawnmower is functioning like new and at 83 I am able to mow the lawn without strain again.

Placed a new side discharge deflector on my mower. No tools were required. New part fell of once after a slight bump but that was the last time I have had any trouble,. Cut yard 2 full times since and it has yet to fall off again.
