drew-mcpherson Drew's Review

The John Deere 770G/GP is an expressive machine packed with features, building on previous models. The standard blade is heavy-duty and the fuel-efficient engine means you get more bang for your buck. All in all, I was very happy with how the 770G performed, and have highlighted some of the key features you should consider before your purchase:

Engine and specs

The engine in the John Deere 770G grader is a lofty 6-cylinder that can deliver up to 243 horsepower while keeping its cool, thanks to the air-to-air intercooler feature. But the machine isn't just a powerhouse: it is also ecologically responsible, with its diesel intake complying with Environmental Protection Agency requirements. The machine runs well on fuel and is cost-efficient compared to some of the competitors on the market. All in all, the John Deere Grader 770 is a smooth and powerful ride.

Visibility and Comfort

On top of feeling good to drive, the 770gp grader is also extremely comfortable for the user. It has a large floor-to-ceiling tinted glass front window, a narrow front console, and a streamlined saddle arm. By making the front windows bigger and the stationary console smaller, John Deere has vastly improved visibility.

All this means that when you are sitting in the driver's seat you have a full view of the work before you. The spacious cabin has a load of amenities, which means the risk of driver fatigue is much lower, allowing for greater overall productivity. The wider backrest gives better lumbar support, while the optional LCD rearview camera lets you see what's happening behind the machine. Operators will be very happy with the comfort of the 770 grader.

Efficient controls and operation

The industry-standard levers and controls of John Deere graders mean that you get a smooth and predictable response from the control panel. The auxiliary functions of the machine are controlled by a set of small levers located to the right of the armrest in an easy-to-reach location. The push button start eliminates the need for a key, but a security feature prevents unauthorised engine ignition until a code is entered.

The auto-shutdown feature means reduced fuel consumption and engine noise while idle. The 770g incorporates EBS transmission, which gives smooth shifting and ultimately improves the material flow across the blade. What's more, who doesn't love cruise control? Operators will be happy to see this feature, which will no doubt reduce stress and fatigue across any job.

Easy serviceability

The John Deere Grader 770 is built to last, but when it comes to servicing, John Deere has also made the job as easy as possible. The fuel tank is at the rear of the machine so that it can easily be filled at ground level. Not to mention, it comes completely protected by a steel guard at the bottom to prevent damage and reduce wear and tear over time. The oil filters for the hydraulic, axle, and transmission are all easy to access in a convenient service bank on the right of the machine.

John Deere has even colour-coded the fluid sampling valves and fluid reservoir caps for simplicity and has made the fluid bank easy to get to for fast refills and evacuations. All machines need regular upkeep to maintain functionality across their lifespan, but the 770G lessens the burden by making the job quicker and easier than ever before.

John Deere 770G Summary

All in all, I think that the John Deere 770G/GP graders are a great improvement on their predecessors, continuing the John Deere tradition of providing solid and sturdy machinery for a range of jobs in the construction and labour industry.

If you decide to go with the John Deere 770, you'll get plenty of grunt out of the powerful engine, without the price tag of hefty fuel consumption and frequent upkeep. If you look after this machine properly, it will certainly go the distance. Your operators will be happy with the comfort and ease of use, and at the end of the day, happy drivers are productive drivers. As with any machine, the 770G is a big investment, but the price tag is fair and relatively affordable for what you are getting.

If you're still not 100% sure that the John Deere 770 is the right piece of equipment for you, why not have a chat with some others who have used this machine and compare it to the demands of your work? Or, if you aren't quite ready to make a purchase or would prefer to save on costs, you can consider hiring the machine and taking it for a test run.
