This ad is for a lot of big wheel surface drive parts. There is enough parts to make a 24' unit and have spares besides. This is available as a lot or as specific items if you do not want to keep spares on hand. Sorry, no picture as the parts are stored in a dark shed. If you have one of these unloaders, then you know what they look like etc. Located west of Ottawa, near Carp. If you're reading this ad then the unloader parts are available. I try and pull my ads the day a deal gets completed. If you want to ensure you hear from me, please include your phone number. I have had ad replies with bad a-mail address's and not been able to get in touch with some buyers. Thanks for looking.
