The John Deere 6920 tractor is an agricultural machinery that is designed to perform a wide range of work using a large number of various attachments. This manufacturer focuses a lot of attention on the performance of the final product, as a result of which almost all machines in the 6020 series have fairly good performance characteristics. This, combined with high quality, reliability and efficiency, has ensured the entire series, including the John Deere 6920 tractor, great popularity in many countries around the world. Currently, mass production of this tractor has been discontinued, however, the machine is very often found in agriculture and, moreover, a lot of completely new equipment is available on the world market.
Under the hood of the tractor there is a six-cylinder engine, usually of its own design and assembly, namely the diesel John Deere 6068T 4V-CR. The engine has a turbocharging system with cooling of the charged air, as a result of which in nominal operating mode a power of 114 kilowatts is achieved, which translates to 155 horsepower.
In its traction class, the John Deere 6920 tractor is one of the most popular models of special equipment designed for a wide range of applications.
Purpose
The John Deere 6920 tractor is most used in agriculture. Here the machine serves as the main hard worker, who is able to single-handedly cope with all the necessary operations. The tractor, paired with attachments, performs a full range of work, which includes: cultivation of row crops, industrial crops, and vegetable crops; preparing the fertile soil layer for sowing; sowing; soil cultivation; harrowing the soil; inter-row cultivation of various crops; harvesting the resulting crop; feed preparation; loading and unloading; transportation of various goods over certain distances.
The tractor also works in large-scale industrial sectors and various large organizations. But it is worth noting that the range of work performed by this machine in these areas is not large, and the tractor is used only for loading and unloading operations and transporting any cargo over various distances.
Reviews John Deere 6920
- Vasily, Tver region. A good tractor is compact and quite lightweight, in demand in agriculture. It produces about 150 hp. s., and at the same time it is distinguished by high high-torque. Fuel consumption is at an acceptable level, as well as other consumables. On our farm, the machine is designed for hilling, cultivating, harrowing and other earth-moving operations. Maintenance is not a cheap procedure, but for the sake of reliability and smooth operation it is worth forking out. The John Deere 6920 is ideal for tug duty and is also suitable for construction site operations. There is noise in the cabin, and vibrations from the engine are transmitted to the steering column, and discomfort occurs. But if you don’t pay attention, it’s generally convenient to drive. In addition, all the organs are at hand, as they say. Overall a normal tractor for a foreign car.
- Sergey, Kursk. The best tractor among foreign cars. I say this without any exaggeration; I already have experience working on foreign cars. Compared to New Holland, the car looks more advantageous - both in terms of efficiency, convenience, and functionality. The John Deere 6920 model supports a variety of attachments and has a maximum lifting capacity of 8,500 kg. A universal device capable of handling cultivation, plowing, harrowing, loading, unloading and other popular tasks. The engine, I would say, is voracious, it consumes a lot of fuel and engine oil. With proper care there should be no problems with reliability.
Attachments
The hydraulic system of the tractor provides for the installation of additional attachments. The hitch on the John Deere 6920 is located in the rear part of the structure, where most of the units are installed; however, optionally the machine can be equipped with a front hitch with an independent power take-off shaft. This allows the tractor to use additional front-type equipment in the work process. The list of units is quite large, but only part of the equipment that is most often used in conjunction with a tractor will be affected. So, this list includes the following types of additional equipment:
- Front loading equipment. Designed for loading any cargo. Mounted in the front part of the tractor structure. The controls are located in the operator's cabin. Is an additional attachment.
- A type of mounted seeders. This equipment is designed for sowing various crops. There are several types of such units, namely pneumatic type, mechanical type, as well as pneumatic and mechanical disc type seeders. All types of seeders are installed at the rear of the tractor structure. There are hydraulic drives that lift and lower the equipment. The unit controls are also located in the operator's cab. A type of mounted seeders is an additional equipment of the John Deere 6920 tractor.
- Mounted precision seeders. These units could be classified as previous equipment, however, unlike them, this equipment has fundamental changes in both design and operation, as a result of which they belong to a separate type of additional attachments. Mounted at the rear of the tractor structure. There are hydraulic drives that lift and lower the equipment. The controls are located in the operator's cabin. Is an additional attachment.
- Attachable chisel equipment. This type of aggregate is intended for subsequent loosening of the soil. There are several different types of chisel tools, which differ from each other in the width of the captured area and their design. Mounted at the rear of the tractor structure. There are hydraulic drives that lift and lower the equipment. The controls are located in the operator's cabin. Is an additional attachment.
- Mounted cultivators. The main purpose of this type of equipment is the same as the previous one, namely loosening light soil. There is also a variety of cultivators that differ in operating principle, width and, of course, design. Mounted at the rear of the tractor structure. There are hydraulic drives that lift and lower the equipment. The controls are located in the operator's cabin. Is an additional attachment.
- A type of mounted subsoilers. This equipment is designed for deep loosening of soil of varying density. There are only two types of subsoilers, namely fang-type units (these are the most common) and disc-type rippers. A distinctive feature of the equipment is a fairly large range of adjustable tillage depths. All types of subsoilers are installed at the rear of the tractor structure. There are hydraulic drives that lift and lower the equipment. The unit controls are also located in the operator's cab.
