I need an estate mower with Walker/Navigator capabilities. A local dealer has a 2000 Walker MT20 with 200 hours offered at $7,000. The blower has been converted to 10.5". The paint and general condition speaks to its low use. It's a one-owner unit that saw about 15-20 homeowner-use hours a year. Does the price strike you as high, or in the ballpark? Will the 20hp Kohler be underpowered? I cut irrigated rye and it tends to be damp, even in the hot summer months. Will the 42" deck overhang the wheels enough to cut the edges of beds without going tediously slow? Thanks for the advice, Walker fans!
