Dollar saving developments

The 670G John Deere grader is not only cost-effective at the outset, but it is fitted out with features that keep operational costs low over the life of the machine. Quick change filters, gauges that are easily within sight, cores that are easy to reach and clean, and a full suite of hardware that can easily be switched out and replaced individually if needed, this machine is made with ease of maintenance and durability in mind.


Quality of build

You can differentiate between the best and worst products on the market simply by looking at the solidness of the build. The John Deere grader 670G doesn’t skimp when it comes to materials. It comes standard with a high-strength draft frame that can endure high-impact loads. Not to mention, this John Deere grader has a blade impact system which adds an extra layer of protection against structural damages in case of accidents or obstructions. When operating this machine, you can feel that it is a sturdy workhorse up to most jobs. The blades are also pre-stressed to ensure lasting durability and high strength when put under pressure.

Fuel efficiency

Another way that the John Deere motor grader saves you money is via its efficient fuel system. It is equipped with a tier 2-certified fuel-efficient nine-litre engine, that boasts the ability to deliver high power and torque without the need to guzzle fuel. Other smart features include variable speed hydraulic fans that only switch on when necessary, meaning less fuel consumption, less noise and less wear and tear. The John Deere grader 670G auto-idle automatically reduces the engine speed at user determined intervals which is another great fuel saving feature. The savings on fuel alone compared with some other competitor machines is a serious factor to consider when purchasing.

Cool, calm, and controlled

It’s all well and good to have the most powerful machine on the market, but if it doesn’t handle well, then it becomes more of a burden than a benefit. The 670G John Deere grader comes with a steering system that automatically adjusts its speed outside the front type, at the same time boosting pull and giving the user the power to achieve full, clean and powerful turns. The front wheels are in good synchronicity with the rear tandems, engaging with ease and allowing for a cool, calm and controlled ride throughout. The 670G John Deere motor grader is really a joy to manoeuvre.


Drew’s verdict on the John Deere 670G grader

If you are looking for a John Deere motor grader that offers performance, practicality and affordability, then look no further than the 670G grader. It will not only help you to achieve time and cost savings, but it will overall enhance the productivity of your operations with its vast array of features. Its reliability and dynamism will help you speed up your jobs, without sacrificing quality.
