Introduction
John Deere 6145M: Row-Crop Tractor
The John Deere 6145M is a row-crop tractor produced between 2015 and 2024 at the Mannheim facility in Germany. Designed for versatility in agricultural operations, this model occupies a mid-range position within the John Deere M-series lineup.
Engine and Emissions
The tractor is powered by a 4.5-liter, 4-cylinder John Deere PowerTech PSS engine. This turbocharged and aftercooled unit delivers a rated power of 145 hp (108.1 kW) at 2100 RPM, with a maximum output of 153 hp (114.1 kW). It complies with Tier IV emission standards using cooled exhaust-gas recirculation, a diesel particulate filter, and selective catalytic reduction technology.
Transmission and Drivetrain
The 6145M offers multiple transmission configurations, including the PowrQuad and AutoQuad PLUS systems. These transmissions feature 16 or 24 forward and reverse speeds, utilizing a four-speed power shift and a wet disc clutch. The drivetrain is available in either two-wheel or four-wheel drive configurations, equipped with electro-hydraulic differential locks on both front and rear axles.
Hydraulics and PTO
The hydraulic system is primarily an open-center design, though a load-sensing closed-center option is available. It provides a pump flow of 21.1 gpm (79.9 lpm) at a pressure of 2900 psi. The independent rear PTO supports dual speeds of 540 and 1000 RPM, operated via an electro-hydraulic clutch for efficient implement management.
Dimensions and Operator Environment
Featuring a 108.9-inch wheelbase and a width of 100.4 inches, the 6145M is built on a standard cab chassis equipped with air conditioning for operator comfort. A two-post folding ROPS version is also available. The rear hitch is a Category IIIN/II system with electronic lower-link draft sensing, capable of providing up to 8456 lbs of lift capacity.
Conclusion
With its combination of power, multiple transmission options, and hydraulic versatility, the John Deere 6145M is engineered to serve as a reliable workhorse for varied row-crop and general agricultural tasks.
