2026 John Deere Landscaping & Grounds Care 622 G-Tier

For almost six decades, John Deere motor graders have been building a reputation for outstanding control and effortless grading precision. Customer input has driven productivity boosters like onboard diagnostics within the primary in-cab display. Durable and jobsite-proven mechanical controls. Same-side service checkpoints designed to save time and effort. And the smaller, budget-friendly 622 G-Tier. Its exceptional balance, optimized performance specs, and reliable capability can help you take grading performance to the next level and your operation in a reimagined new direction.

Features May Include:

Controls to Choose from

Fingertip: Integrated into each armrest, EH fingertip controls replace traditional front-console levers while keeping the same control pattern. Steering can be controlled by using the lever on the left armrest or with the steering wheel.

Joystick: The dual-joystick option requires minimal hand motion during direction changes and gearshift while still giving the operator intuitive control over the machine. This helps reduce operator fatigue compared to other common joystick controls. Steering can be controlled by using the left joystick or with the steering wheel.

Antler rack: The more traditional motor grader controls are still available with the G-Tier offering

Foundational Circle Options

Premium Circle is a fully sealed bearing style circle that is a John Deere exclusive. The premium circle eliminates the maintenance associated with a traditional circle such as insert replacements and adjustments. The premium circle only requires greasing every 500 hours. The premium circle also increases circle torque up to 40% and speed by up to 15% compared to the single input circle.

With the reduction in maintenance costs and no need for shimming the premium circle is a feature that adds value back to the operation.

Dual Input Circle uses a two hydraulic motor inputs and significantly improves the durability of the circle drive gearbox. The dual input circle provides similar circle rotate torque & speed as the single input circle and is recommended for applications that frequently rotate the circle under heavy loads.

Keep maintenance simple, easy, and practical

Ground-level service access – All daily service points [including fuel and diesel exhaust fluid (DEF)] are conveniently grouped on the left side and are easily accessible from ground-level through one door. All periodic maintenance is oriented on the right side of the machine using easy to access vertical spin-on filters.

Single Input Circle uses a single gearbox and is a good solution for customers rotating the circle under lighter loads.

Superior cooling package – With easily accessible coolers and a hinged swing-out fan assembly, the cooling package is quick and easy to maintain. The variable-speed and auto-reversible fan helps keep the machine running cool by quickly cleaning debris from the coolers. All models offer standard reversing fan

Features with the operator in mind

Overview

John Deere continues to use its proven transmissions with 8 forward and 8 reverse gears. The Motor Grader offers two options in manual or Auto-Shift Plus. Auto-Shift PLUS adds additional functionality for the operator by modulating the clutches and reducing/removing the need for the inching pedal. This simplifies the needed operator inputs for starting and stopping the machine. Auto-Shift plus also offers Hill Hold and adjustable RPMs to further enhance their experience while plowing snow at high speeds or fine grading around obstacles.

Event Based Shifting

Event Based Shifting (EBS) is transmission shifting logic that senses the load on the engine as well as other inputs to determine the optimum shift time when the operator selects a new gear. The inching pedal is not required when performing directional changes (shuttle shifting) or changing gears. This logic gives John Deere the edge on transmission performance in grader applications.

Auto-Shift Plus

Allows operators to seamlessly transition from a stop to full speed without shifting or using the inching pedal. This is achieved by modulating the torque through the transmission, instead of the transmission acting as a direct drive. Auto-Shift automatically shifts between gears 4-8 for roading applications. Auto-Shift Plus functionality can be configured in the monitor.
