During construction, a machine is often needed that has high power and productivity, is easy to operate, but at the same time has low fuel consumption. The John Deere 850J bulldozer meets these characteristics. In addition, from the model range of its class, it is the one that has the greatest digging depth. The installed transmission does not allow the caterpillar track to reduce cross-country ability in unfavorable conditions, while guaranteeing maximum traction in various power modes, reducing fuel consumption and maintenance costs in relation to other types of transmission.
Bulldozer John Deere 850J
Most 850j models were purchased for waste transport applications. The developers took into account all the necessary details and elements that reduce the operator’s labor costs when working with equipment, as well as protective coatings that are resistant to any substances.

Peculiarities
The main feature of the John Deere bulldozer is the installed transmission. Its operating principle is hydrostatic with full functioning. Thus, the car does not slip, has a smooth ride, and can use dynamic braking. In addition, the power does not decrease during the maneuver. Thanks to this type of transmission, the John Deere 850J has high performance, long service life and efficiency.

Engine
The company itself produces this power element. The model is called PowerTech 6081 and runs on diesel fuel. The installation consists of six cylinders that are constantly in a humid environment. They have a positive effect on the operating time of the engine, and also reduce the fuel consumption of the John Deere 850J to 320 g/kW per hour . The volume of the fuel tank is 370 liters. Engine power is 185 horsepower (138 kW), it is equipped with turbocharging and ONV. If during operation the motor refuses to work, the manufacturer is ready to fix the problem. In this case, repairs are carried out using special technology, and the service life of such an engine will be longer. The rotation speed of the unit is 1800 rpm with a torque of 800 Nm.
| Parameter | Meaning |
| Model | PowerTech 6081 |
| Number of cylinders | 6 |
| Working volume | 8.1 l |
| Power | 138 kW /185 l. With. |
| Rotation frequency | 1800 rpm |
| Cooling type | liquid |
To protect the engine from overheating, an automatic system is provided. It is responsible for the temperature of the oil in the engine, the operation of the transmission and the pressure in the hydraulic system (the volume of the hydraulic tank is 106 l). The protection system has three levels. John Deere 850J bulldozers supplied to the Russian Federation have specific functions. For example, they are adapted to work at low temperatures, using fuel produced in Russia. At the same time, the quality of exhaust gases complies with international standards. The maximum traction force of the bulldozer is 520 kN.
To carry out a technical inspection before starting operation, you need to look under the car. All necessary elements are visible from the ground. This arrangement also has a positive effect on the speed of maintenance.

Device
The model has a separate-aggregate layout. The tractor design includes three parts. The rear and front axles have an axle with a diameter of 100 mm and a length of 3048 mm. The John Deere 9430 has dual rear and front wheels. The equipment has the ability to attach ballast weights. They are installed on the frame and axles, allowing you to significantly increase the weight of the tractor.
The John Deere 9430 tractor is equipped with an automatic step-by-step transmission “Automatic PowerShift”, the gears of which are meshed, and the friction clutches have an electro-hydraulic control drive. This allows the equipment to move at a speed of 2-42 km/h. The innovative PowerShift system allows you to change gears without reducing or interrupting the flow. The operator, taking into account changes in the load on the tractor, can select the appropriate operating mode.
The hydraulic system of the model is made according to the principle of a load-sensitive system. It is built on the basis of an adjustable “Closed System” pump with a capacity of 182 liters per minute. The minimum configuration of the John Deere 9430 includes a fork for interaction with trailed agricultural machines. Only the American brand equips its products with the unique TouchSet system, which allows you to effectively control the hydraulic system. Using it, the operator can set the required flow for each valve of the sectional hydraulic distributor directly during movement.
The tractor has a deluxe CommandView operator cabin that offers unsurpassed convenience and comfort. The redesigned design provides more space for the operator. The operator's cabin features excellent sound insulation, completely preventing extraneous sounds from entering the cabin. The latest backlit instrument panel makes it easy to see and control indicators and instruments at night. The driver will also be pleased with the ClimaTrack temperature control system, which automatically maintains the temperature conditions inside the cabin at a set level. Functionally, the client can order a heated ActiveSeat seat, leather upholstery and a steering wheel braid. The operator's cabin itself significantly reduces the level of driver fatigue, allowing him to always remain alert and fresh. Among the useful options present in the John Deere 9430 model are radar, delayed lighting switch-off and dual power adjustable mirrors.
A large and bright monitor allows you to monitor engine speed, travel speed, transmission and other functions. The CommandCenter LCD display allows you to program and control the operation of 20 diverse systems and functions. All this makes working at John Deere 9430 more productive.
Important How and where can you get a license to drive a bulldozer?
The model is mainly used in agriculture. This determines the specificity of the line of additional equipment used in conjunction with the tractor. Here are present:
- subsoiler;
- disc harrow;
- combined unit;
- mechanical seeder;
- disc pneumatic seeder;
- disk subsoiler;
- chisel plow;
- cultivator;

Service
Transmission and hydraulic filters, as well as the battery, are located directly behind the large doors. This arrangement guarantees the speed of replacement or other manipulations with them. There are locks on the doors.
The cabin can tilt 70 degrees, which also allows access to the hydrostatic system. Separate tanks for hydraulic fluid are provided to avoid oil contamination in both systems at once.
To find out the reason for the equipment failure, just look at the monitor in the cockpit. It displays the error code and description in Russian. The code is necessary for the service center, and the description is necessary for the ability to troubleshoot minor problems yourself at the work site. This has a positive effect on reducing wasted time.
