Im selling my 2006 Ditch Witch RT40. It has a H314 Trencher Attachment. The handbook mentions that the trencher has a capability of digging a 52 Inch deep trench, but i myself have never tried going that deep. Its a super strong tractor that can be versatile. I know Ditch Witch sells a bunch more attachments that can be used with it. The Ditch Witch has 1642 Hours on it. But it still starts right up. The diesel engine on it has been a super reliable engine. No leaks. Starts right up. Ready to be put to work. The Trencher is in great shape still. The tires of course still hold their air as well. Let me know if you have any questions. Ill be happy to answer. Feel Free to come by and try it out.
