New Holland 8260 Range Command Diesel

Last Updated: July 2024

Overview

The New Holland 8260 Range Command Diesel is a row-crop tractor featuring a selective gear fixed ratio transmission with partial (6) range operator controlled powershift, providing 18 forward and 12 reverse gears. It has a closed center load sensing hydraulic system, hydrostatic power steering, and a 4x2 2WD chassis configuration. The liquid-cooled 6-cylinder diesel engine from New Holland (Genesis model) has a displacement of 456 cubic inches, a bore of 4.4 inches, and a rated speed of 2200 RPM. Independent testing revealed a maximum power output of 107.0 HP at rated engine speed, with a maximum torque of 330 lb-ft at 1456 RPM and 29.19% torque rise. Drawbar performance peaked at 84.5 HP with a 7395 lb pull at 4.28 mph in 9th gear. Hydraulic capabilities include a 24.0 GPM pump flow rate at minimum pressure, delivering 34.6 HP at 2470 psi, with a maximum 10,116 lb force exerted through the hitch points. Fuel efficiency was measured at 17.00 HP-hr/gal at standard PTO speed. The tractor has single wet disc hydraulic brakes operated by foot pedals.
