I'm not sure if this is the right forum for the following question but I thought if you were unable to help you might be able to suggest other forums etc. which may be more appropriate. (I have already posted this on AboristSite.com) I have the opportunity to buy the attached mulcher, not sure what the exact make and model is, the little information I have is 'Twin Disc, Incorporated, Racine, Wisconsin, 53403, USA', model no somewhere between WS09 - WS12. About 4 to 5 years old but laid up for most of that time, only 494 hours. Any suggestions for current value?
