NEW JOHN DEERE 700K SMARTGRADE™ DOZER OFFERS CONTRACTORS A COMPETITIVE EDGE The John Deere 700K SmartGrade™ crawler dozer is improving jobsite accuracy and quality of work through its complete integration of the Topcon 3D-MC2 Grade Control System. The system is fully integrated into the machine cabin, structures, and software – delivering precise grading performance while eliminating vulnerable external masts and cables. The SmartGrade technology enables operators to be more productive on the jobsite. Because SmartGrade is integrated into the 130 hp 700K, it removes the need to install equipment daily, reducing setup time. Eliminating external cables to the masts reduces breakage, and the
removal of the masts from the blade eliminates vulnerability to damage and theft. The Auto SmartGrade feature allows the operator to easily adjust the system when moving the machine from one soil type to another, unlike an after-market system, which often requires the GPS manager to make a trip to the machine to recalibrate the system. Especially helpful to new operators, Auto SmartGrade
automatically lifts the blade over heavy loads before track slippage occurs, then returns the blade to grade. SmartGrade also limits the number of passes required, reducing the pace of wear on the undercarriage. Machine dimensions are preloaded into the grade control monitor, reducing the time required to calibrate the dozer to about 30 minutes. Additionally, the easy-to-use system is beneficial to new operators in that it can get them up and running quickly. SmartGrade dozer can pay back its purchase price in one to two jobs. Cc
NEW DESIGN FOR CAT® 630K SERIES WHEEL TRACTOR-SCRAPERS INCLUDES TECHNOLOGY THAT ADDS PRODUCTIVITY AND OPERATOR CONVENIENCE The new Cat® 630K Series wheel tractor-scrapers—631K and 637K—replace the previous 630G Series and feature a complete design update, including high-pressure steering, engine-over-speed protection, tire-spin reduction, differentiallock-engagement protection, and machine/ground-speed control, plus available systems such as Sequence Assist, Load Assist, Payload Estimator, and Cat Grade Control. Payload capacity of the open-bowl 631K and open-bowl twin-engine 637K is 34 cubic yards and 50 cubic yards for the coal-bowl 637K. Redesign of 630K Series models also includes a number of features developed for other Cat K Series models: the Advanced

Cushion Hitch uses new software to dampen end-of-stoke movement of the load cylinder for a smoother ride; hydraulicsystem refinement simplifies the bowl quick-drop function; and draft-arm-overflow guards divert material away from the sides of the bowl. In addition, a new Auto-Stall system assists in quickly bringing the transmission to operating temperature for faster transitions from torque-convertor drive. New

cab interiors feature a redesigned dash, as well as visibility and operator-comfort enhancements. Maintenance improvements include a ground-level-service filter bank, and the 637K’s Fuel Economy Mode adjusts shift points and power distribution for optimum fuel economy. Engine over-speed protection automatically senses engineover-speed conditions, based on the rate of acceleration, and applies the compression brake or service brakes with no operator input. Cat Grade Control, when selected, “intelligently” controls the loading cycle to ensure that the machine does not cut below grade avoiding excess material movement and rework. Cc
