The John Deere 870G motor grader is a robust 4WD machine engineered for precision earthmoving and road maintenance applications. Powered by a John Deere PowerTech PSS 9.0L turbocharged diesel engine, it delivers 209 kW (280 hp) net power with peak torque of 1,430 Nm (1,066 lb-ft) and a 53% torque rise. The six-cylinder, 9.0-liter displacement engine features eight forward and eight reverse speeds, enabling optimal gear selection for varied terrain and operating conditions. Maximum blade pull reaches 15,501 kg (34,173 lb), providing exceptional material handling capability. The 870G accommodates a full 360-degree moldboard circle with superior articulation and circle design. Its frame articulation of ±22 degrees and front axle oscillation of ±32 degrees ensure stability on uneven ground. The blade base measures 2,530 mm (8 ft 4 in), while overall dimensions span 6,160 mm (20 ft 3 in) wheelbase and 3,180 mm (10 ft 5 in) height over ROPS. Operating weight reaches 20,715 kg (45,668 lb) with attachments, while maximum configured weight approaches 24,948 kg (55,000 lb). The closed-center, pressure-compensated load-sensing hydraulic system produces maximum flow of 212 L/min at 18,961 kPa (2,750 psi), ensuring responsive blade and steering control. Advanced features include Eco mode fuel optimization reducing consumption by 10%, auto-shutdown capability, and compatibility with John Deere's industry-leading SmartGrade automated grade-control integration for enhanced productivity and grading accuracy.
