In general, the John Deere 7830 tractor cabin features an increased level of functionality and excellent ergonomic design.

Feedback from John Deere 7830 tractor owners

In their reviews, the owners of these modern tractors no longer hear the surprise and admiration of the comfortable working conditions in the cabin, created for the mechanic, competent and thoughtful arrangement of his workplace, excellent visibility and design. There is almost the same comfort in the cabin as in passenger cars, and the work in such favorable conditions does not cause fatigue.

It is noted that John DIR-7830 successfully and effectively combines the features of Caterpillar and wheeled machines, replacing two tractors “DT-75” or “MTZ-80”. This eliminates the cost of obsolete machines. For the same work, diesel fuel savings of twenty percent are achieved. However, the cost of a John Deere tractor is very high.

However, John Deere 7830 tractor owners are comforted by the fact that the high cost of this model in relation not only to less powerful tractors, but also to similar tractors, is compensated by its reliability, durability and maintenance of technical parameters throughout the whole lifespan at a high level.

tractor-johndeere-7830

However, durability of John Deere tractors largely depends on the quality of diesel fuel and oil, on the skills of the machine operators, and on the performance of the tractor equipment during normal operating conditions. Many farmers are simply afraid to trust such expensive equipment even to experienced, but careless “other good” hired operators. Preferably on their own or with the help of particularly proven and reliable workers.

Of course, John Deere 7830 tractors require special training for workers and maintenance personnel before they can be operated on a regular basis. Repairs to major and optional equipment are so complex that it’s usually impossible to do it yourself in the field.

Dealerships are expensive to service these tractors, parts are not always available and, according to owners, cost “crazy money,” “as if they were made of gold. But in times of trouble “one day nourishes an entire year,” and there is no need to stand behind the price. That’s why John Deere 7830 tractors only work on farms that are solid, provide consistently high productivity and generate reasonable profits.

There is also anecdotal evidence that “John Deere tractors used to be of much better quality. The ones that are produced now, especially the Chinese and Russian-made ones, are not of this quality. Perhaps it is the desire to reduce the cost of production… “However, such statements do not have a high degree of credibility.

The dealers themselves testify that both in recent years and today “there are tractors that have been sold and forgotten about, and there are tractors that barely work anymore. As for the quality of assembly, one farmer remarked that “Mexicans at the American John Deere plant also assemble tractors like we have jumshuts”.

The price of a used John Deere-7830 tractor

John Deere updates its tractor program as often as major automobile manufacturers update their cars. The John Deere-7830 has already been retired and has not been produced since 2012. The series continues with even more modern and “advanced” machinery.

There are few ads for used tractors of this brand on the secondary market. The average cost of a tractor from 2007-2011 is about 4-5 million rubles.
