![]() ![]() The after-treatment system was simplified with the removal of the DEF system and related components, eliminating the future need to add additional fluid to the 450 P-Tier model. “Now customers don't have to worry about adding DEF to the machine throughout the work week on that 450 P-Tier model.” “We wanted to give customers a less complex, simpler after-treatment system while reducing maintenance,” Goedert said. ![]() On the 450 P-Tier, the company has entirely removed the DEF system. ![]() “That's a proven, reliable engine,” he said. Goedert noted that the P-Tier small dozers have the same 4.5-liter engine in them as the previous series. Maximum Life: Provides the same benefits as extended life with the use of SC-2 coated bushings, along with larger components with more wear material on the rollers (upper & lower), chain links, idlers, and seals.The extended bushing life allows you to maximize the wear life of other undercarriage parts. Extended Life: Uses proprietary SC-2 coated bushings designed to double the bushing life compared to standard bushings.Standard Heavy-Duty: Uses a sealed and lubricated track chain with hardened steel pins/bushings and polyurethane seals to keep lubrication in and abrasives out.John Deereįor the undercarriages, John Deere offers a variety of options to help balance component wear and get the most life out of them before performing maintenance. In addition, hydraulic hose and electrical harness routings have been optimized throughout to minimize rub and leak points.Įach of the machines offers ground-level filter access.Įach model provides ground level access to engine oil dipstick, fill and filter. John Deere said there are reduced maintenance costs across the small dozer line with extended hydraulic oil change intervals to 4,000 hours. Under the company’s naming strategy and designations, all John Deere machines that are part of the P- or X-Tier solutions that have electrohydraulic controls will have at least EZ Grade factory-installed.Īll models also are compatible with laser receivers, helping to control elevation and slope while utilizing a rotating laser.Īn additional 10-inch touch-screen display for navigating the grade control interface is added when the machine is outfitted with dual-laser receivers. Goedert said these dozers are technology-packed, offering smarter, more intuitive operations.īase models with electrohydraulic (EH) controls arrive from the factory with EZ Grade, John Deere's entry-level grading solution. The proportional blade angle roller switch is also integrated into the stick controls. Instead of moving the joystick forward and reverse to change directions, it is integrated into a simple rocker switch on the left joystick,” he said. “This reduces operators’ hand and arm movements. Goedert said the joystick controls from Deere’s mid-sized dozers have been integrated into the small dozers for low-effort ergonomics. Lastly, the general control of the dozers has also been simplified. In addition, an operator can set a maximum desired ground speed, and the power-management system automatically maintains peak engine speed and power efficiency without stalling or shifting.ĭeere says counter-rotation enables on-the-go blade repositioning. It also displays the machine’s configurable settings. John DeereVia the SSM, buttons are all centralized to enable features such as automatic turbocharger cool-down, auto shutdown, auto idle, and eco mode.įurther, the touchscreen displays not only the rearview camera but also makes navigation and interaction with slope control and other function easier. The various new technology offerings are integrated into easy-to-use touchscreen displays. In addition, John Deere says, the Sealed Switch Module (SSM) reduces the number of wires and mechanical switches and provides keyless start. The hydraulic and transmission response settings can be set to fit any operator's preferences. The company also has taken into consideration that every operator is different with varying techniques and preferences. In controlĪ new operator-presence system uses a built-in sensor to detect that the seat is occupied before the park brake is released to prevent unintentional movement. An optional LED light package and a rearview camera are displayed on a larger and brighter 8-inch touchscreen monitor. ![]()
