The key to great grading is excellent visibility, and we deliver.


Excellent Visibility
Visibility is key to productive grading. The D4G delivers excellent visibility to the blade corners and edges. No longer does an operator have to grade by feel. He can easily see blade corners and cutting edges. Wide open peripheral vision allows the operator to have an optimum view of the jobsite.

Large, tinted windows provide excellent visibility to the blade and surrounding work site. Large, sliding side windows provide flow-through ventilation. With 13% more glass area, the operator station delivers an outstanding view all around the machine.

Angled Doors
Angled doors on the left and right hand sides provide virtually unrestricted visibility to the sides of the machine.

Excellent Line of Sight to Blade
Grade stakes and utility structures are easy to see and maneuver around with the G-Series tractors.

Step up to a new machine. The G-Series machines have a new look, one that will have everyone eager to operate them.


Updated Look
The G-Series machines feature a new, more appealing look with rounder corners, new operator compartment and a sleeker shape.

Solid Machine
The new G-Series machines are solid tractors that are well-equipped. From the hexagon shaped cab which originated on large Caterpillar track-type tractors to the sleek, narrow hood, the D4G combines eye-catching styling with solid, reliable performance.

The well-proven Caterpillar 3046 six-cylinder engine provides smooth, responsive power, excellent fuel economy and lasting reliability.


Caterpillar 3046 Diesel Engine
Designed specifically for small to medium size earthmoving machines, the Cat six-cylinder 3046 engine is inherently balanced, providing low vibration, superior performance and exceptional responsiveness. A 25% torque rise at 1400 RPM provides increased lugging force during heavy loads.

Direct Injection Fuel System
The direct injection fuel system is adjustment free for reduced maintenance. High pressure fuel injection results in reduced fuel consumption and emissions. Electric, internal fuel shut-off solenoid is protected from the elements to provide long life.

Spin-on Oil and Fuel Filters
Spin-on oil and fuel filters are vertically mounted and easily accessible for faster maintenance.

In-cylinder Glow Plugs
In-cylinder glow plugs deliver dependable starts when operating in cold temperatures. A built-in temperature switch helps ensure lasting reliability.

Lubrication System

The Caterpillar 3046 engine meets Tier I EPA, MOC and CE regulations.

Hydrostatic Transmission Control
Simple joystick control eases operation and increases productivity.

Hydrostatic Transmission Control

Simpler Operation, Improved Control
We listened to our customers and designed the new G-Series machines with even simpler operation and improved control. This allows the operator to concentrate on more important aspects of the job such as blade control.

Joystick Control
The joystick control is easy to use. Speed, direction and steering are all controlled with the joystick. The result is easier operation and improved productivity. Ergonomic placement reduces operator effort and fatigue.

Speed and Direction
The joystick has three simple detented positions for travel: forward, reverse and neutral. A new feature is the capability to utilize faster reverse speed as a percentage of forward speed for increased productivity. Two joystick-mounted buttons are used to infinitely increase and decrease speed. An indicator on the dash displays the tractor's current operating speed setting. When the joystick is moved to the neutral position, the machine stops.

With the machine moving in forward or reverse, move the joystick to the left to turn the machine to the left; move the joystick to the right to turn right. The more the handle is moved to the right or left, the tighter the turn. Regardless of ground conditions, steering is consistent and predictable. Moving the joystick to the far right or left will make the tracks counterrotate for maneuvering in tight work areas.

The D4G maneuvers easily through side loading blade applications. Simply engage counter- rotation briefly to correct machine position. Counterrotation also provides easy, quick maneuvering in small, confined work areas.

The D4G has excellent tracking capabilities which increase productivity on side slopes.

Utilizing active effort of both tracks during a turn allows for more pushing power at the blade and less spillage of material from the blade.

Durable components provide maximum performance and wear life.


Durable Components
Advanced metallurgy processes produce improved life for bushing and sprocket segments. Segmented sprockets (standard equipment) offer easy serviceability and low replacement cost compared to replacing the complete sprocket hub. Caterpillar undercarriages are designed for long wear and lower owning and operating costs.

Complete Guarding
Caterpillar undercarriages are designed with full length guarding on top of the track roller frame. This prevents abrasive material from falling down on moving parts.

Available Configurations
The D4G is available in either an extra long (XL) or low ground pressure (LGP) undercarriage configuration.

XL Undercarriage
Track length is extended on extra long (XL) undercarriages for increased ground contact area and flotation, superior balance and excellent finish grading.

LGP Undercarriage
The low ground pressure (LGP) undercarriage offers a wider track, increasing ground contact area for optimum flotation and greater stability on sloping and finish grading jobs. In addition, the G-Series LGP undercarriage is offered with an additional roller versus the C-Series.

Blade and Mainframe
With a 14% increase in blade capacity, the Variable Pitch, Power Angle and Tilt (VPAT) blade is designed and built for unmatched versatility, durability and strength.

Blade and Mainframe

VPAT Blade
The VPAT blade is specifically designed for finish grading, backfilling ditches, cutting V ditches, windrowing, fill spreading, medium land clearing and heavy dozing. VPAT blades are built with four full-width (three on intermediate and LGP), box-section reinforcement cells for unmatched strength and durability.

Increased Blade Capacity
Blade capacity has been increased by 14% to greatly improve productivity.

Larger Trunnion
The blade trunnion ball size has been increased to provide longer life of the trunnion and reduce owning and operating costs. The trunnion is also now mounted on the C-frame instead of the blade.

Adjustable Top Pitch Link
The adjustable top pitch link provides a solid link between the blade and the top of the tilt tower on the C-frame. The turn buckle top pitch link allows the blade pitch to be adjusted without the use of tools. The cutting edge position can be adjusted between 50 and 55 degrees. The pitch link cover has been redesigned to provide better retention.

Improved Pin Joints
Pin joints have been improved to be more durable and provide longer life. Remote lubrication points provide easier service.

One-Piece Mainframe
Modeled after the large Caterpillar track-type tractors, the mainframe provides a solid back bone for handling forces generated during tough dozing. The robotic welding process delivers reliability and durability throughout the life of the machine.

Hydrostatic Winch
Providing high line pull and high line speed, this new winch improves control for better modulation.

Hydrostatic Winch

Hydrostatic Winch
Previous mechanical winches were driven by shafts and controlled by brakes and clutches. This new winch is driven by its own closed-loop hydrostatic system consisting of a variable displacement hydraulic piston pump and motor.

Infinitely Variable Speed Control
Similar to the hydrostatic system used to drive and control the tracks of the tractor, this winch offers outstanding control of the load with infinitely variable modulation of speed and pull. Other shaft-driven winches force the operator to choose the gear ratio of the winch. The G-Series hydrostatic winch eliminates this compromise by providing the speed of a standard speed winch and the pull of a low speed winch, all in one package.

Forestry Segment
A new, easier way to work in the woods. The new hydrostatic winch makes the job easier with:
  • Excellent line pull at any speed
  • Infinitely variable drum speed
  • Lower operator effort
  • Excellent load control

360 Degree Guarding
All around screen guarding is available. Canopy version includes screened, hinged doors with dampening device along with side and rear screens. The cab version offers Lexan glass doors for improved visibility while providing protection. Meets OSHA and WCB regulations.

The new parallelogram ripper and hydrostatic winch make the D4G even more productive on your jobsite.


Parallelogram Ripper
This new, larger tool is more aggressive and allows the operator to do more effective ripper work. Heavy duty design provides long life. Parallel linkage design allows for better penetration and maneuverability in tight working areas. A longer shank delivers more work per pass making the machine more productive.

Product Link
This option allows the customer or dealer to obtain machine diagnostics and location from their office, eliminating trips and phone calls. Scheduled service can be completed more efficiently, thus reducing owning and operating costs. The Product Link provides updates on service meter hours and machine location as well as integrated mapping/route planning.
