GRADING/SITE PREP Products Caterpillar D7 High Drive Dozer The 265-hp D7 dozer sees Caterpillar’s return to the high drive undercarriage design, with the elevated sprocket undercarriage delivering better ride and balance as well as increased penetration force. A fully automatic four-speed transmission ensures optimal dozing, fuel efficiency and ease of operation. The 65,644-lb. unit incorporates a completely redesigned cab with more space, multiple seat and control adjustments and a 10-in. touchscreen operator interface with standard high definition rear view camera shown in the main display. The ARO with Assist gradeready option is bundled with basic blade control and a new set of assist features. The D7 is also available with integrated Cat GRADE with 3D and comes Remote Control Ready from the factory for use with Cat COMMAND for Dozing. Standard or low ground pressure (LGP) configurations are available, along with specialized waste/landfill and forestry/land clearing guarding.

Trimble Earthworks Grade Control Platform 2.0
The 135-hp 700L and 175-hp 750L include a John Deere six-cylinder, 6.8-liter engine and offer wider blade options, including a 161-in. option. • Can be equipped with a factory-installed slope control to automatically maintain blade angle without the need for external laser or GPS reference • Slope control machines also SmartGradeready for easy upgrade to a full 3D mastless system • Spacious operator station with ergonomically designed EH controls, 7-in. color monitor that can interchange to show grade control information, 14% larger door openings, better visibility to blade and 50% noise reduction (700L) • Include optimized hydraulic hose and electrical harness routings plus 4,000-hour hydraulic and hydrostatic oil change intervals
The Earthworks Grade Control Platform version 2.0 features Horizontal Steering Control that automatically controls the dozer to follow any horizontal alignment such as a back of a curb, breakline, roadway centerline or bottom of slope without operator assistance. • Augmented reality for excavators enables users to understand 3D models, cut/fill information, slope data and other bench points and reference points on the in-cab display in context, without the need to interpret complex 2D plans or stakes • Mastless motor grader configuration gives operators an improved range of blade motion • Integrated LOADRITE Payload Management displays grade control and payload data on one screen, preventing under- and overloading

John Deere 700L and 750L Dozers
Liebherr PR 736 Generation 8 Dozer Liebherr introduces its Generation 8 crawler dozers to the North American market with the PR 736 G8. The hydrostatic drive unit weighs up to 56,218 lbs. and is powered by a 217-bhp Liebherr Tier 4 Final diesel engine. Various blade versions (straight, semi-U and six-way) are available in capacities from 5.36 to 7.27 cu. yds. The OAS – Operator Assistance System offers a “Free Grade” level for active blade stabilization during fine grading, “Definition Grade” level for automatic blade positioning when creating 2D grades and “3D Grade” option to model complex terrain shapes. The dozer includes standard roof-mounted GPS/GNSS antennas and onboard Active Sensor Control to stabilize all blade axis. Electronically pilot controlled work hydraulics allow for swift, highly precise work cycles.

CASE DL550B Compact Dozer/Loader Initially introduced at CONEXPOCON/AGG 2017 as “Project Minotaur”, the production version DL550B leverages the footprint of a compact track loader (CTL) with the chassis-integrated C-frame and blade of a dozer to create a powerful two-in-one machine for grading and loading applications. It features a true dozer-style undercarriage for optimal dozing performance and is available in steel or rubber track configurations. The roughly 18,000-lb., 114-hp unit features a six-way blade and its C-frame attaches directly into the chassis and primary coupler of the machine. This design provides the stability and smooth operating plane of a small dozer and ensures all operating power and stress is channeled through the chassis instead of the attachment coupler and arms. To transition to CTL-style operation, the operator simply hydraulically detaches the C-frame and blade to match up with a bucket, forks or other skid-steer and compact track loader attachments. Major changes compared to the original concept include an evolution from radial to a vertical lift geometry and an increase in rated operating capacity from 4,500 up to 5,500 lbs. (50% tipping load).

Komatsu intelligent Machine Control 2.0 The intelligent Machine Control (iMC) provides proactive dozing control that can operate automatically 100% of the time and is more than 60% more productive than the previous generation. • Automatically cuts/strips from existing terrain like an experienced operator • Lift layer control automatically spreads fill with a press of a button • Measures the terrain it tracks and uses that data to plan the next pass • Tilt steering control automatically tilts blade to maintain straight travel during rough dozing • Creates a temporary design surface also at a press of a button
Dressta TD-16N Dozer The 170-net-hp TD-16 dozer has an operating weight of 42,090 lbs. and features a mid-cab design with all-round visibility encompassing 309°. • Mid-mounted automatic dual path hydrostatic drivetrain • Standard six-way angle blade • Compatible with 2D and 3D grade control systems • Easily accessible, intuitive electrohydraulic joystick controls • Undercarriage design uses a single track gauge for all track shoe widths, allowing easy reconfiguration from standard to LGP undercarriage simply by changing the track shoes and blade
