Recent Design Overhaul

Deere's new D-Series range of motor graders, introduced a bit more than a year ago, reflect significant design enhancements compared to their C-Series counterparts. New to the Deere range with the D-Series are the six-wheel-drive 872D and its tandem-drive companion model, the 870D. The standard cab forthe D-Series is a low-profile design, but a full-height or "tall" cab is optionally available.

Number of models: 6

New models: 670D, 672D, 770D, 772D, 870D and 872D

Product-line features: In addition to new emissions-compliant engines, the D-Series features redesigned moldboard and draft-frame geometry, new pressure-compensated/load-sensing hydraulic system, new cab and new transmission-control system (Event-Based Shifting). The new shift-control system electronically senses load and speed parameters, and then determines optimum engagement/disengagement rates for hydraulic clutches to promote smooth shifts. Operational directional changes can be made without the inching pedal.

Case motor graderCase

Floor-to-Ceiling Glass

According to Case, the operator's environment of its 800-Series motor graders provides optimum comfort and convenience. With 85 square feet of floor-to-ceiling glass, the cabs are designed to provide all-around visibility, plus the cabs are secured with an "Isomount" system that is designed to reduce noise and vibration. In addition, the cabs are located on the frame to provide clear sight lines to the moldboard and tires for precise blade positioning.

Number of models: 4

Product-line features: Case graders feature six-cylinder Cummins diesel engines, with the dual-horsepower 865DHP using the Cummins QSB5.9. All use direct-drive powershift transmissions with an inching pedal, and the 8F/4R transmission can be shifted manually or turned over to an automatic system. Optional extensions allow adding two feet to each end of the moldboard, and a five-position saddle can tilt the blade to 90 degrees.

Is Something Missing Here?

If you haven't yet heard, Caterpillar's new M-Series motor graders replace the conventional motor grader's steering wheel and multiple control levers with two multi-function, three-axis joysticks. These controls in its new seven-model M-Series range, says the company, can reduce operator hand and arm movement by as much as 78 percent. M-Series models will replace the 10-model H-Series range, beginning in October 2006 and continuing through mid-year 2007.

Number of models: 7

New models: 120M, 12M, 140M, 160M, 14M, 16M and 24M

Product-line features: The M-Series design goes beyond the new joystick controllers to include the company's ACERT engines, new direct-drive countershaft transmissions with electronic clutch-pressure control (except the 24M), modular rear axle and a new hydrostatic front-wheel-drive system (120M, 140M and 160M). Variable horsepower is standard on the M-Series, and a new power-management system delivers horsepower in increments of five as transmission gear ranges step higher. A new system for maintaining adjustment of the drawbar, circle and moldboard makes this chore much easier, says Cat.

LeeBoy motor graderLeeBoy

Choose Compact or Production Models

LeeBoy's three-model range of motor graders includes two smaller, hydrostatically driven units — the 6,700-pound 635 and the 15,000-pound 685B — and a larger model, the 785, which weighs in at 25,000 pounds.
