Dual Joystick Controls

Our new dual joystick controls provide motor grader operators with intuitive, ergonomic control.

A History of Innovation

Celebrating 50 Years of the Articulated Motor Grader

1961

The 4XE Project

Through its 4XE project, John Deere begins experimenting with cutting-edge motor grader ideas, including a tandem-drive assembly, front-mounted scarifiers, and articulated steering.
1967

Articulated-Frame Steering

John Deere introduces the JD570, the first motor grader to feature front-wheel and articulated-frame steering, providing operators more maneuverability than ever before.
1968

The 4XM Prototype

The 4XM prototype – with its innovative maneuverability and performance advantages – affirms Deere’s ambition to challenge competitors in the over-145-hp motor grader market.
1970

Experimentation

Deere begins experimenting with hydrostatic front-wheel drive, placing a Waterloo hydro-wheel-powered axle into a JD570 grader.
1971

A Lasting Update

The JD570, updated with several performance and durability improvements, is renamed the JD570A. It remains in production until 1986.
1975

Low-Cost Alternative

In August, the JD670 is introduced as a lower-cost alternative to the JD770, which was introduced earlier that year, and other graders in the 115-145-hp market.
1978

Hydrostatic Front-Wheel Drive

The 672A and 772A – Deere’s first motor graders featuring hydrostatic front-wheel drive – begin rolling off the production line.
1985

Variable Horsepower

The launch of the 770AH and 772AH motor graders introduces variable horsepower.
1987

A New Model

Production of the 570B motor grader begins. It remains in production until 1996.
1997

PowerShift Plus

With a slew of innovative features – headlined by the PowerShift Plus direct-drive countershaft transmission – the C-Series ushers in a new era for Deere motor graders.
2002

Fuel Distribution Advancement

The C-Series-II pairs an electronically controlled, high-pressure fuel-delivery system with a 106-gal. fuel tank, for more precise and consistent fuel distribution. It also sees a significant update to the front-wheel drive, which provides true dual-path hydrostatics.
2005

Introduction of D-Series

The D-Series makes its debut. New innovations include Deere’s exclusive Event-Based Shifting transmission, the pressure-compensated load-sensing hydraulics system, and a redesigned cab. The Series update in 2007 will introduce Integrated Grade Control.
2009

Providing Choice

In addition to cross-slope control, automatic differential lock, and a rearview camera, the all-new G-Series offers an industry first – a choice of console-mounted standard controls or armrest-mounted fingertip controls.
2011

IT4

Six G-Series motor grader models are updated to include Interim Tier 4 engines.
2013

FT4

The entire G-Series motor grader line is upgraded to meet Final Tier 4 emissions standards.
2017

Innovation Continues

Boasting updates to key customer specifications, two new motor grader models (620G/GP and 622G/GP) continue our history of innovation with the introduction of an ergonomic shifter, a high-resolution in-cab monitor, and the new dual joystick control option.
