It consists of four components, including Proactive Dozer Control, which is grade control that can be used 100 percent of the time. The iMC system gives operators more automation features and makes them easier to activate. The D71 will be the largest hydrostatic dozer with factory-integrated machine control on the market, Komatsu says. Komatsu’s D71PXi-24 mid-size dozer became the company’s first machine to offer the second-generation intelligent Machine Control platform. Komatsu D71 integrates latest iMC version To learn more about the 700L and 750L, click here. When opting for Slope Control from the factory, the machines also come SmartGrade-ready to upgrade to Deere’s 3D mastless system in the future. Deere says this system automatically maintains blade angle without an external laser or GPS reference. A heated and ventilated seat is optional.ĭeere is also offering a factory-installed, entry-level grade control system called Slope Control. Cab noise has been cut in half, the company says. The cabs can be equipped with optional automatic temperature control and a rearview camera. New electro-hydraulic controls have been added. It now weighs 37,569 to 40,040 pounds.ĭeere increased cab size 17 percent and increased operator visibility with larger windows. Deere has also increased the operating weight of the 750L by 750 pounds. The 700L weighs 30,900 to 32,088 pounds, depending on the configuration. They are primarily aimed at site development, roadbuilding and underground construction. John Deere says its new 700L and 750L dozers can run all day while keeping the operator comfortable.

The torque converter features a stator clutch to increase efficiency and fuel savings.

Optional technologies include slope indicate, slope assist, Cat Grade with 3D, Blade Load Monitor, Stable Blade, Traction Control and AutoCarry, which automatically lifts and lowers the blade to maintain more consistent blade loads and limit track slip. It features a High Drive undercarriage design that Cat says provides a smoother ride, better stability, long track life and easy cleaning. Deere has also gone with an in-line DEF filter on these models for easier replacement.The new D7 also packs more weight and power. Plus, the sheet metal on the service doors of the machines is 50 percent thicker with improved sealing. That should save you 13.5 percent in fluid and filter costs over the life of this machine. We actually have a cable in there that if you were to get a branch or something in there that would help to keep those hoses from getting ripped out.”Īdditionally, hydraulic and hydrostatic oil change intervals are extended to 4,000 hours, reducing operating cost. Another wrap around the hoses going to the blade. “All the hoses are externally wrapped in a metal spring. “The engineers spent a lot of time to make sure each hose and harness had its own location to make sure it wasn’t rubbing against anything,” Horstman says. To increase uptime, these next generation dozers have optimized hydraulic hose and electrical harness routings to reduce the possibility of rub points. When opting for slope control from the factory, the machines also come SmartGrade-ready, should you want to upgrade to Deere’s 3D mastless system in the future. “Slope control essentially allows an operator to input a cross slope and a main fall angle and make a very basic slope or basic pad without the need for GPS or GNSS satellite coverage or without the need for like a laser elevation reference,” Horstman says. For novice operators, that means hitting grade more accurately, while veteran operators should be able to hold grade with less effort. Deere says this system automatically maintains blade angle without the need for an external laser or GPS reference. “So when the operator is looking from the right side to the left side of the blade, he or she can cross through and check out the grade control monitor.”ĭeere is also offering a factory-installed entry level grade control system called slope control on these machines. “Another improvement we made with this new 700L dozer is we actually raised up the grade control monitor not only so you can interact with it more but also to get it in line of sight with the blade,” Horstman says. The cab on these machines also features a new 7-inch color monitor that displays need-to-know operation data and grade control information.
