CAT 14H MOTOR GRADERS

Technical Description

The 2005 CAT 14H Motor Grader is a robust, tandem-drive machine designed for heavy-duty grading tasks, featuring a 14 ft moldboard with a 26 in height and a roller chain pitch of 2 in. It is powered by a 6-cylinder diesel engine, delivering approximately 176–196 hp net power across a 1500–2200 rpm range, with engine displacement between 7.0 and 9.3 L. The hydraulic system utilizes a closed-center, variable piston pump, providing up to 24,000 kPa (~3500 psi) for reliable implement control. The grader’s tandem oscillation allows for 15° front and 22–25° rear articulation, enhancing stability on uneven terrain. The blade offers a maximum lift of 18.9 in above ground and a tip forward angle of 40°, while the steering system supports up to 47.5° of front wheel articulation and ±20° frame articulation for precise maneuverability. The transmission is a direct-drive powershift with 8 forward and 6 reverse gears, enabling smooth speed transitions from 2.9 mph in 1st gear to over 15 mph in 6th gear. The machine meets EPA Tier 2 and EU Stage II emissions standards, and its base operating weight typically starts around 33,000 lb, varying by configuration. The 14H’s design emphasizes durability, operator comfort, and efficient performance for a wide range of earthmoving and road maintenance applications.
