I have a chance to buy a Walker MT20 with ~600 hours on it. It is a 20 HP with a 52" deck. The mower is supposedly in excellent condition and has recently received new blades, 2 new tires on the back and one new spindle. It needs a hydraulic strut on the back replaced but other than that and a few scratches where the paint needs touched-up it is in good shape. I'll get to see it and test it tomorrow but I wanted to get an idea of what a fair price would be. Any suggestions? Thank you.
