I recently came across a 6' wide drag harrow to replace my older 4' model. I went online to search for a supplier but all the usual local stores sold only the complete unit and not the tow bar only. I finally came across the Nest Attachments website at www.NeatFarms.com. I was immediately impressed by the ease of navigation and clear information directing me to the right tow bar for my drag. I placed my order, received confirmation and several follow-up messages describing shipping status.
