Overview

The John Deere 7R 270, also known as 7270R Diesel or e23 Diesel, is a powerful row-crop tractor. It features a 4x4 MFWD chassis with power steering. The tractor is equipped with a John Deere 6-cylinder, twin turbocharged diesel engine with 414 cubic inch displacement, delivering 270 hp and a rated PTO power of 227.46 hp. The engine has a 16.0:1 compression ratio and produces a maximum torque of 822 lb-ft at 1500 rpm with a 44.3% torque rise. The transmission is a selective gear fixed ratio with a range of power shift, electronically limited. The hydraulic system is closed-center pressure flow compensated, capable of 58.5 GPM flow at 2773 psi. The tractor weighs 24,265 lbs and is fitted with 420/90R30 front tires and 480/80R46 rear tires. Its advanced cooling system includes an engine coolant heat exchanger for crankcase oil and a radiator for hydraulic and transmission oil, with two thermostats and a variable speed fan.
