How much should I ask for my Grasshopper 61" mulching kit--used once

[sixdogs]

I bought a new GH 725DT 61" mower last year with a 61" mulching kit but traded the deck for a 72" one after once use. I forgot I had the mulch kit so I have one to sell. It's metal baffles, end chute and blades in almost mint condition. It rally works great. How much should I ask for it?

New they go for $275 to $300
