Description and features

The model stands out in its segment with increased power indicators and a high-quality hydraulic system, thanks to which the machine has a very wide range of applications. Many analogues are significantly inferior to this backhoe loader in cost, but this is compensated by the ability to install two buckets at once.

Among the main features of this model, the following should be highlighted:

1. The cab is equipped with digital sensors, through which the operator can monitor the number of working hours, hydraulic pressure, and crankshaft speed.
2. The equipment has excellent visibility when operating at night, which is due to ten powerful headlights. There are 4 headlights in the front, exactly the same number in the rear, and there are 2 more on the side of the cabin.
3. The braking system includes wet disc brakes with a liquid cooling system.
4. The boom equipment mechanism has an increased safety margin, which ensures long service life and resistance to high loads.
5. The rear wheel axle of the machine is supplemented with a differential lock, which serves to increase the maneuverability of the backhoe loader.
6. The cabin is standardly equipped with a multifunctional display that displays the main parameters of the machine. With its help, the operator can diagnose all equipment systems, which greatly facilitates maintenance.
7. The equipment has excellent smooth running and gear changes, which is explained by the presence of its own PowerShift transmission.

The John Deere 325J backhoe loader has a four-by-four wheel arrangement. A special function is provided that allows the operator to connect the front axle drive, which increases the machine's maneuverability on various types of soil. This function is activated via a separate button located on the control panel. Also, in order to improve this indicator, the model is equipped with two differential locking devices, both on the rear axle and on the front.

A distinctive feature of the braking system is increased efficiency and, most importantly, safety. The braking system includes wet disc brakes with a cooling system that uses oil as coolant. The equipment is equipped with a spring-loaded parking brake. Its opening occurs due to the drive of the hydraulic system. Thanks to this solution, the operator can turn it on using a button located on the control panel. A rather interesting and convenient feature is that the braking system, in particular the parking brake, begins to function automatically after the power plant is turned off. This also made it possible to increase the level of safety, since even if the operator forgets to put the car on the parking brake, this system will do it for him, thereby preventing various emergency situations. It is worth noting that the brake will not require adjustment and maintenance even after quite a long period of use, which has a positive effect on saving money when repairing the machine.

The hydraulic system of the backhoe loader has two pumps, the individual capacity of which is about 130 liters per minute. This element of the model is almost completely automated, since when the pressure in the hydraulics decreases, the system automatically connects the pumps, thereby ensuring constant operating pressure and at the same time reduced fuel consumption. Another feature of the hydraulics of the John Deere 325 backhoe loader is the high digging force of 67.8 kilonewtons, which translates to 6913.7 kilograms. In this indicator, the model is far superior to most competitors.

The model can be equipped with a telescopic handle, which allows for increased efficiency when performing excavation and loading types of work. The proposed handle has an external moving part, thanks to which it was possible to prevent dirt and dust from entering the retractable mechanism, thereby increasing its service life.

The operator's cabin is distinguished by fairly modern ergonomics and comfort. It is equipped with a multifunctional display that displays all information and equipment parameters in Russian, which is especially convenient for Russian consumers. If the system detects any malfunctions in the operation of certain elements, this display will instantly display a corresponding alert indicating the cause and the problematic element, which guarantees accurate and quick troubleshooting. The standard cab configuration is equipped with an air conditioning system, ten headlights and a heater, which ensures the most comfortable working conditions.

The manufacturer has eliminated possible jerks when shifting gears and provided the equipment with a fairly good smooth ride by installing an improved PowerShift transmission system. In addition, this transmission allows you to realize the full power of the power plant and has very simple and convenient control, which is due to the location of the gearshift lever on the steering wheel.

On the right side of the model there is a spacious fuel tank. The fuel tank is characterized by a reduced amount of condensate and increased resistance to corrosion processes, which is explained by the use of modern technologies and materials in the manufacture (mainly high-strength plastic was used). The reliability of the product is also due to the installation of a metal box that protects the tank from mechanical damage. The capacity of such a tank is 155 liters of fuel, which ensures long-term operation without stopping for refueling. Its location was chosen extremely conveniently. It has a wide neck, thanks to which it was possible to eliminate fuel spillage and guarantee simple and quick refueling directly to the ground.

The backhoe loader hood can open to an angle of 90 degrees. This provides easy access to the engine compartment. In the same space, all nodes that require regular checking are located in blocks. It is worth noting that in order to get to such elements there is no need to lift the boom mechanism of the front loader, which is quite convenient. The front part is equipped with a metal radiator grille made using high-strength materials. The grille is distinguished by its resistance to damage as a result of falling objects from a height.

In order for the owner to save money when maintaining the equipment, the manufacturer has equipped the machine with a built-in fault detection system, which signals the occurrence of any problems during operation of the machine. The output information is provided in the form of text material, when in many other models only a problem code is often displayed, which is precisely what makes the equipment a leader in its segment. A useful function is provided that checks the functionality of all elements without the need to start the power unit.

At the customer's request, the John Deere 325J backhoe loader can be equipped with a variety of different additional attachments to significantly expand the scope of application. The most popular options at the moment are various types of buckets and working bodies (handle and boom). But in addition to this, there is a lot of equipment, including a front blade, a hydraulic breaker, utility brushes, forks and many other types.
