FWIW, I just got the salvaged 2166 project up and running and on first use am reminded of just how well built the 2000 series are and how well they drive and mow. It's possible I've got an unsolvable dichotomy in the front lawn has too many trees and flower beds for anything larger than the late-lamented 2135, but the 2166 with 48" deck certainly makes easy/short work of the rough 1/2-acre of back lawn. Once I get the belt-driven-fan-assist bagger attached, it will be too large for tight spaces.
