Excavators Feature a Host of Improvements

John Deere's D-Series hydraulic excavators feature Tier-3-compliant engines, as well as a long list of hydraulic, structural and cab changes. These six excavators range in operating weight from 54,244 to 185,520 pounds, and in horsepower ratings from 177 to 532. The new 240D LC, 270D LC and 350D LC feature John Deere PowerTech engines, while the three larger models — 450D LC, 650D LC and 850D LC — use Isuzu engines. All feature a sleek new cab with a brand-new monitor that allows programming hydraulic parameters for attachments, as well as operating and diagnostic parameters. Estimated list price: $350,000 (for the 350D LC).
