Ive been a long time reader but this is my first time posting maybe you guys can lead me in the right direction. I have the opportunity to buy a 3 year old exmark walk behind with the 32 inch deck. The seller says it has about 300 hours on it. Hes got the grass catcher and the attachment to stand on. He says hell let it go for $800. Does it sound reasonable.He said he says he has a Kohler engine on it. Thanks ahead for any replies.
