Up to 620 Horses, 9070kg Hitch Lift Capacity and Efficiency: John Deere’s 9R Series

powertech_psx13.5_l_engine_204x138John Deere has expanded its range of high horsepower tractors, with the recent introduction of the 9R/9RT 4WD Series. The Series includes the 9420R, 9470R, 9520R, 9570R, 9620R and 9470RT, 9520RT and 9570RT, ranging — as the names suggest — from 420 to 620 horsepower.

Designed for large arable farms with hillside terrain and tough field conditions, the 9R Series utilizes Tier 4 Final/Stage 4 compliant engines. On the 9520R, 9570R and 9620R models, the engine rides on a HyrdaCushionSuspension System, which is located on the front axle where its role is to mitigate power hop and road lope, thereby delivering all of the horsepower to the ground.
