JOHN DEERE 790D CRAWLER EXCAVATOR

Technical Description

The John Deere 790D is a mid-size hydraulic excavator engineered for versatile earthmoving and construction applications. Powered by a John Deere 6466A engine, this machine delivers 165 gross horsepower and 155 net horsepower at 2100 rpm, generating maximum torque of 510 lbs-ft at 1300 rpm. The turbocharged engine with aftercooler ensures reliable performance across demanding job sites. The 790D features three configurable boom and stick options to accommodate varying project requirements, with maximum digging depths ranging from 20.5 to 24.7 feet and maximum reach along ground extending from 31.3 to 35.2 feet. The bucket capacity options of 0.8 to 1.4 cubic yards provide flexibility for different material handling needs. Operating at a weight of 53,143 pounds, the machine maintains excellent ground pressure of 7.3 psi, minimizing site disturbance. The hydraulic system operates at 4,980 psi relief pressure with a 124.8 gallons-per-minute pump flow capacity, delivering responsive boom, stick, and bucket control. The undercarriage incorporates 47 shoes per side with an 8-foot track gauge, providing stable traction and 37,250 pounds of drawbar pull. With a maximum travel speed of 2.8 mph and swing speed of 12 rpm, the excavator efficiently repositions between work zones. The machine's 9.6-foot cab height and 9.7-foot tail swing radius enable operation in confined spaces, while the compact 9.9 to 10.5-foot shipping height facilitates economical transport. This combination of power, precision, and maneuverability makes the 790D suitable for trenching, grading, loading, and general construction work.
