Last Updated: July 2024

Overview

The Agco RT140a is a robust and versatile utility tractor equipped with a powerful Sisu Diesel engine with a displacement of 6.6L (402.8 ci). The tractor features a Continuously Variable Transmission (CVT) with 24 forward and reverse gears. The engine is electronically controlled to provide two power levels, with a maximum power output of 180.4 hp at 2000 rpm and a rated power of 153.8 hp at 2200 rpm. With an operating weight of 16,305 lbs, this tractor is designed for heavy-duty agricultural tasks. The hydraulic system has a pump flow capacity of 30.5 gal/min at minimum pressure and 26.5 gal/min at maximum hydraulic power, with a maximum observed pressure of 2845 psi. The tractor's maximum torque is 595.3 lb-ft at 1400 rpm, with a torque rise of 62.0%. Detailed fuel consumption rates across different conditions are available from the test results. The RT140a also features a Category II-IIIN three-point hitch with a maximum observed lift force of 17,335 lbs. Additional features include sound level data, information on tire configurations and ballast weights, and manufacturer details from the test results.
