Attachments Moldboard plow attachment

Does anyone out there have the moldboard plow attachment for their deere. My husband would like to have an attachment for his 500 mower to make it easier for him to continue gardening. I have contacted several JD dealers in the area and all have told me that they have never sold this attachment but it does have a part number. From what i can tell there is an additional part i need to get to make the unit go on to the mower. The cost isnt cheap but would be great if it reallydoes what it says it does. Is there anyone out there who has this attachment and can give me their input.

If your talking x500 series you would need the sleeve hitch.They make a manual and a power one.Here is the manual.
