John Deere 9630T

Last Updated: July 2024

Overview

The John Deere 9630T is a powerful and durable track tractor designed for demanding agricultural and earthmoving tasks. Powered by a 6-cylinder John Deere PowerTech Plus turbocharged aftercooled diesel engine with a displacement of 826 cubic inches, it delivers an impressive 530 horsepower at 2100 rpm. The engine features a compression ratio of 16.0 to 1 and a nominal turbo boost pressure of 29.0 - 32.6 psi (200 - 225 kPa). The tractor's cooling system includes three thermostats and a variable ratio fan. The 18-speed PowerShift transmission provides smooth and responsive gear shifts, with detailed gear ratios and travel speeds available from the test results. The hydraulic system, using John Deere Hy-Gard fluid, offers impressive performance with detailed pressures and flow rates provided. The tractor's operating weight ranges from 43,920 lbs unladen to 52,755 lbs with ballast and operator. The test results also provide comprehensive data on drawbar performance, noise levels, and three-point hitch performance, including a maximum force exerted of 16,070 lbs (71.5 kN).
