Ask This Old House

Riding Lawnmowers; Garbage Disposers; Rotting Threshold (3x22)

:

Roger heads to Alpharetta, Georgia to help homeowner Dale Eneberg shop for a new riding lawnmower. Then Roger, Richard, Tom and Kevin ask, "What Is It?" Later, Tom replaces a rotting wooden threshold for homeowners Steve Chapman and Maggie Hale of Arlington, Massachusetts. And, back in the loft, Richard shows Kevin how garbage disposers work and explains how to keep them working like new.
