Last Updated: July 2024

Overview

The New Holland TN70DA (manufactured by CNH America LLC, Racine, WI, USA) is a turbocharged utility tractor powered by a 3-cylinder vertical Iveco Diesel engine (Fuel No. 2 Diesel) with a displacement of 179 cubic inches and a compression ratio of 18.0 to 1. The engine has a bore and stroke of 4.094" x 4.528" and a rated speed of 2484 rpm. Independent test results show a maximum power output of 60.5 hp at 2245 rpm and 60.2 hp at the standard PTO speed of 539 rpm. The tractor is equipped with a 16-speed selective gear fixed ratio transmission and a dual dry disc clutch. Detailed hydraulic performance data includes a pump flow capacity of 17.1 gal/min at minimum pressure and rated engine speed, and relief valve pressures of 3010 psi in the high flow option and 2975 psi in the standard option. The tractor has a maximum torque of 190.6 lb-ft at 1442 rpm and a torque rise of 39.8% with a 19% rise at 1800 rpm. The power take-off speed is 540 rpm at 2196 engine rpm or 1000 rpm at 2260 engine rpm. The test results provide comprehensive information on drawbar performance, hydraulic performance, noise levels, center of gravity, fuel and oil specifications, and weight details. The length and height dimensions from the original data remain unchanged.
