Introduction

John Deere 4620 Row-Crop Tractor

The John Deere 4620 is a row-crop tractor produced in Waterloo, Iowa, between 1971 and 1972. It represents a significant model in the evolution of the brand's heavy-duty machinery, positioned between the 4520 and 4630 series.

Engine and Performance

The tractor is powered by a 6-cylinder, 6.6-liter (404 cubic inch) intercooled turbocharged diesel engine. It features a liquid-cooling system and a dry air cleaner with a safety element. The engine operates at a rated speed of 2200 RPM, with a compression ratio of 16.4:1, providing the necessary torque for demanding agricultural operations.

Transmission and Drivetrain

Two transmission options were available: a partially synchronized John Deere Syncro-Range (8 forward, 2 reverse gears) with a 14.75-inch dry disc clutch, and a full power-shift transmission (8 forward, 4 reverse gears) utilizing hydraulic wet discs. The tractor features a 4x2 2WD configuration with an optional 4x4 HFWD system. Traction is aided by a hydro-mechanical rear differential lock and planetary final drives.

Hydraulics and PTO

The 4620 is equipped with a closed-center hydraulic system, with a capacity of 60.6 liters for the Syncro-Range version and 68.1 liters for the Power Shift version. The independent rear PTO operates at 1000 RPM, achieved at a rated engine speed of 1900 RPM, providing consistent power for implements.

Dimensions and Operator Environment

The machine rests on a 270 cm wheelbase and offers significant ground clearance, measuring 17.8 inches at the drawbar. The operator station is of the open type, with optional two-post Roll-Gard ROPS, canopy, or a full cab. Front and rear tread widths are highly adjustable to accommodate various row-crop configurations.

Conclusion

"The John Deere 4620 is a robust row-crop tractor designed for medium to heavy field work. With its combination of turbocharged power and flexible transmission choices, it remains a notable machine for collectors and professionals requiring reliable mechanical performance from the early 1970s era."
