1989 model with 1999 Deutz diesel engine that starts & runs great. This thing can sit for months & will jump to life when you hit the ignition without using starting fluid. Doesnt smoke or use oil, hydrostatic, 4x4, dozer blade, good rubber(front tires are brand new), front wheel weights, new Shark tooth carbide tipped digging chain on a 48in. boom with removable side augers for cuttings, digs roughly 8-9in.wide & about 42in. max depth trenches. It has no safety features, you can walk beside it & trench if needed, but that is not recommended. Im selling it as is with no warranty. I bought this for a project about 10 years ago. The hour meter reads under 400 hours, though I cant guarantee its original, this unit operates like it has low hours. I am only selling it because I have no good reason to hang onto it anymore as its hardly been used the past 5-6 years. Delivery is negotiable. Its ready to go to work for you!
