I have a 647a for sale or trade. Unit has 100 hrs on it hasn't been used all year and only a couple of hrs last year. Looks, cuts, and feels like brand new. Only thing I have done to it is changed the oil. Has mulch kit installed since new. Have extra set of blades too. Will not find one this clean anywhere. Maybe able to help with delivery. Will trade for a walk behind, tank sprayer, renovation equipment, or just let me know what you got. Wife says this has to go.
