Introduction
John Deere 4930 Row-Crop Tractor
The John Deere 4930 is a row-crop tractor manufactured in Waterloo, Iowa, USA, between 1978 and 1981. Primarily exported to the Argentinian market, this model shares technical characteristics with the United States-based John Deere 4440.
Engine and Performance
The tractor is powered by a 7.6-liter (466 cubic inch) inline 6-cylinder diesel engine. It features direct injection, turbocharging with an intercooler, and a liquid cooling system. The engine produces 160 hp (119.3 kW) at a rated speed of 2200 RPM, with an operating range between 1500 and 2200 RPM. Starting is assisted by an ether injection system.
Transmission and Drivetrain
The 4930 offers two transmission configurations: a 16-speed partial power shift (Quad-Range) and an 8-speed full power shift. Both utilize a hydraulic wet disc clutch. The Quad-Range transmission provides four gears across four ranges, with power shifting available between pairs in each range. The tractor is available in either 4x2 2WD or 4x4 HFWD (High Front Wheel Drive) configurations.
Hydraulics and PTO
The hydraulic system is a closed-center design, delivering a pressure of 2250 psi (155.1 bar). The pump flow capacity is 23 gpm (87.1 lpm) for the 2WD model and 26.5 gpm (100.3 lpm) for the 4WD version. The independent rear PTO operates at 540 and 1000 RPM, utilizing a 1.375-inch shaft.
Mechanical and Dimensions
The machine features power steering and hydraulic wet disc brakes. The rear hitch is a Category III/IIIN system with position and draft control. The wheelbase measures 106.7 inches (271 cm), with an overall length of 158.6 inches (402 cm). Optional equipment includes the Sound Gard cab with integrated air conditioning.
Conclusion
The John Deere 4930 is a high-horsepower, conventional row-crop tractor designed for heavy-duty field operations. Its combination of robust engine output, multiple transmission options, and substantial hydraulic capacity makes it suitable for intensive agricultural tasks requiring high traction and implement control.
