The John Deere 672G motor grader is a powerful and versatile piece of equipment designed for heavy-duty grading and road construction tasks. Part of the well-regarded G-series lineup from John Deere, this model combines advanced technology, ease of operation, and durability to deliver optimal performance in a wide range of applications.
In this article, we will explore the features, benefits, and common concerns of the 2011 John Deere 672G, shedding light on why this grader continues to be a popular choice for contractors and operators working in construction and maintenance of infrastructure.
Engine and Performance
The 2011 John Deere 672G is equipped with a Tier 4 Final compliant engine, which delivers 235 horsepower from its 6.8L, 6-cylinder engine. This engine provides the power necessary for various grading tasks, including leveling, finishing, and scarifying. Additionally, the engine features improved fuel efficiency, a common trend among modern machinery to reduce operating costs and environmental impact.
With a hydrostatic transmission, the 672G delivers smooth and responsive operation. The system allows for seamless speed changes and fine adjustments when working in tight spaces or challenging terrain. The powerful engine and efficient transmission ensure that the grader can handle even the toughest jobs with ease, making it suitable for construction, road maintenance, and even snow removal in colder climates.
Key Features of the John Deere 672G
1. Advanced Hydraulics System
The hydraulic system of the John Deere 672G motor grader is designed to provide ample power for blade lifting, lowering, and angling. The open-center hydraulic system delivers consistent pressure, ensuring that the grader operates at maximum efficiency.
The Blade Control System (BCS) provides precise control of the blade's movement, allowing the operator to make fine adjustments for accurate grading. The advanced hydraulics make it easy for the operator to manage the machine's performance across a variety of tasks, from basic leveling to complex road repairs.
2. Improved Operator Comfort and Visibility
John Deere has focused on enhancing operator comfort and visibility in the 672G, making it a more productive and user-friendly machine. The Visionary™ cab is spacious and equipped with an air-suspension seat, climate control, and low-noise levels to reduce fatigue during long shifts.
The cab is designed to offer 360-degree visibility, allowing operators to have a clear view of the blade, tires, and the work area. This is a critical feature for improving both productivity and safety, as operators can ensure the work is progressing as planned and identify potential hazards in real-time.
3. Intelligent Machine Features
One of the standout features of the 672G is its Grade Control System (GCS). This system allows the operator to achieve more accurate grades, reducing material waste and rework. The Grade Control System is particularly useful in maintaining consistent slopes and depths, especially when working on roadbeds or grading large areas.
The system integrates GPS and laser-based control, offering real-time data on the machine’s position and the surface being worked on. By using these systems, operators can achieve a more precise final grade, reducing human error and speeding up the completion of grading tasks.
4. Enhanced Maneuverability and Stability
The articulated frame design of the 672G enhances its maneuverability, allowing it to easily navigate tight spaces and handle curves while maintaining stability. The machine’s front wheel drive (4WD) provides excellent traction in challenging conditions, whether working on soft soil or frozen ground.
The oscillating rear axle helps maintain consistent ground contact, improving the grader’s overall stability and preventing tipping when working on sloped terrain.
Applications of the John Deere 672G
The 2011 John Deere 672G motor grader is built to excel in a variety of industries and tasks, including:
1. Road Construction and Maintenance
The 672G is ideally suited for road construction and maintenance, where its ability to level surfaces and smooth roads is crucial. It is commonly used for tasks such as road bed preparation, grading shoulders, and ensuring proper drainage. The precision and efficiency of its hydraulic system make it an ideal tool for building new roads or repairing existing ones.
Example: A contractor working on a highway expansion project used the John Deere 672G to prepare the subgrade for asphalt paving. The machine’s laser-guided grade control system ensured that the surface was perfectly level, leading to a smoother, longer-lasting finished road.
2. Mining and Quarrying
In mining and quarrying, the 672G can be used to grade access roads, create safe working platforms, and clear material. The stability and powerful hydraulics of the machine are valuable when working in rough, uneven terrain often found in quarries.
3. Snow Removal
During winter months, the John Deere 672G is a reliable piece of equipment for clearing roads and highways of snow. The machine’s ability to maneuver through snowdrifts, adjust blade angles, and clear wide paths makes it an essential tool in municipal snow removal operations.
Story: During the winter of 2018, a city’s road maintenance crew relied on the John Deere 672G for snow clearing operations after a major storm. The machine’s hydrostatic drive and Grade Control system ensured that roads were cleared swiftly and efficiently, minimizing disruptions and ensuring public safety.
Common Issues and Maintenance Tips for the John Deere 672G
While the John Deere 672G is a highly reliable grader, like any piece of heavy equipment, it requires routine maintenance to stay in top condition. Some of the most common issues reported by operators include:
1. Hydraulic System Leaks
Over time, hydraulic components may experience wear and tear, leading to leaks. Regularly checking the system for leaks and replacing worn seals or hoses will keep the grader’s hydraulic system running smoothly.
Tip: Keep the hydraulic fluid levels checked and ensure that any hydraulic hose replacements are done with high-quality parts that meet John Deere specifications.
2. Tire Wear and Tear
The 672G can put a lot of strain on the tires, especially when used in rough conditions like construction sites or quarries. Regular tire checks and proper inflation are essential for maintaining the machine’s traction and preventing premature tire wear.
Tip: Inspect the tires regularly for signs of excessive wear or damage. Ensure the tread depth is sufficient, and rotate the tires if necessary to promote even wear.
3. Cooling System Issues
As with many high-performance machines, overheating can be a concern, especially during extended operation in hot environments. Regular maintenance of the radiator and cooling system is vital to prevent engine overheating.
Tip: Keep the cooling system clean, especially during the warmer months when the machine is more likely to be working for long periods. Check the coolant levels regularly and flush the system as recommended in the operator's manual.
