John Deere 700L and 750L crawler dozers feature improvements that enhance productivity, reliability, and operator comfort, including an all-new operator station, increased power levels, low-effort electro-hydraulic (EH) controls, and a suite of factory grade-control solutions.
The 700L and 750L deliver more power than the previous K-Series models, with 135 and 175 horsepower, respectively. The new crawler dozers are equipped with a six-cylinder, 6.8-liter John Deere engine. In addition, operating weight of the 750L is increased by 750 pounds, providing more tractive effort and better balance to improve machine performance, says the company. The dozers are available with new, wider blade options, including a 161-inch option, the widest blade offered for the 750L. Integrated spill sheets on the 700L blade further increase blade capacity.
Both dozers can be equipped with a new factory-installed slope-control system, designed to automatically maintain blade angle without an external laser or GPS reference. The slope- control machines are also SmartGrade-ready, creating an easy upgrade path to a full 3D, mast-less system in the field, says the company. The new machines also have “optimized” hydraulic-hose and electrical harness routings to reduce the possibility of rub points. Hydraulic and hydrostatic oil change intervals are extended to 4,000 hours.
The new operator station is a ground-up redesign, says the manufacturer, with a focus on visibility and operator comfort. Featuring 15 percent more volume and 14 percent larger door openings, the new operator station is designed to provide enhanced visibility to the blade. Standard EH controls are designed to reduce operator fatigue and to facilitate grade control installation in the field. Additional cab features include a premium heated/ ventilated seat, rear camera, automatic temperature control, and reduced sound levels (a 50-percent reduction in the 700L, compared with the previous model). A new, 7-inch color monitor can interchange to show grade control information as well.
