Benefits and Testimonials
The popularity of the DZ98 grader is based on numerous advantages. These include:
1. Ability to use various attachments.
2. Ability to work on soils of different density.
3. High level of overcoming obstacles.
4. Easy to operate.
5. Ability to adjust the blade width and the degree of penetration.

9. Replaceable attachments for various construction work.
10. Possibility of using a motor grader when temperature conditions from minus 50 to plus 50 degrees.
Numerous reviews indicate that many years later, the DZ 98 grader remains one of the most popular in its class. One significant drawback is seen constant among the reviews. This is an insignificant gas contamination of the cabin during operation. It exists on old models of technology. Modern machines equipped with improved gas evacuation devices, ventilation and air conditioning systems are installed in the cabins.
The DZ-98 "ChSDM" motor grader is, to some extent, a "visiting card" of the domestic mechanical engineering in the field of special equipment. This is a machine for leveling ordinary soil and rocky embankments, removing a layer of earth up to 0.5 meters thick, removing ice and snow, moving large masses of loose cargo (sand, gravel, crushed stone). There have always been a lot of such works in Russia - for example, the construction of railway embankments, the preparation of areas for construction, the cleaning of large sections of roads from snow and ice in cold weather. In this regard, many design ideas and inventions in terms of how to make a machine are reflected in the design of the motor grader:
- very maneuverable with a large mass - about 20 tons - and length;
- highly passable;
- powerful;
- equipped with a set of universal tools, incl. rotary, for the above works;
- moving at a "decent" speed (in the first gear - 3-4 km / h, in the 6th - 41-47 km / h) equally forward and backward;
- maintainable (including modular replacement of any hydraulic cylinder) and quickly readjustable to another attached tool.
What is the uniqueness of the design of the DZ-98 motor grader, what can it
Even when considering the numerous photos of a motor grader on our website, it can be noted that the DZ-98 (approx.: the version of the DZ-98V grader differs in the power plant model - the presence of a diesel engine YaMZ-238ND2, -ND3) in its constructive layout, it is absolutely unlike all other special vehicles, except for analogs of competing manufacturers. This is a kind of "lunar rover", universally equipped to perform its functions, with three drive axles, six forward and reverse speeds(due to the checkpoint with a multiplier), high ground clearance and frame main blade, the angle of rotation of which can be unlimited.
On Russian market road and construction machinery, there is no other type of special vehicle (for example, if we compare the characteristics with a bulldozer), which could turn the blade at such large angles:
- 360 degrees for full-turn blade(the design provides for a blade rotation reducer);
- 0-64 degrees from transverse axis cars - for part-turn.
Attachments DZ-98. How dumps work
Moreover, the DZ-98 grader is equipped with two swivel blades - the main front and side auxiliary... The machine is equipped with both bulldozer and track laying, loosening equipment, special knives and brushes. For example, the DZ-98V1.4 modification is a grader with a YaMZ-238ND2 diesel engine, with bulldozer equipment and a scarifier.
The working body of the machine - a moldboard knife, raking the rock - in the process of moving the grader back and forth, it can rise, fall, turn when controlled from hydraulics, performing planning works on all soils up to fractured rocks. The slide-out and rotating side plow, for example, is good for clearing snow and can also be replaced with a ripper.
Important: about working hydraulic cylinders
All working bodies of the machine are controlled by powerful reliable hydraulic cylinders with rod diameters of 100-160 mm. The design contains hydraulic cylinders:
- removal of the frame;
- front blade extension;
- blade rotation;
- lifting - lowering the blade;
- side blade extension;
- power steering, etc.
Note that the presence of a power steering makes a special vehicle with large-diameter wheels even more maneuverable, despite its large dimensions and only seeming external "clumsiness".
If the owner of a motor grader, when performing work in a large volume at a remote site, has spare cylinder kit(this is a small financial investment in 2018 prices - only 140-150 thousand rubles), replacing a damaged cylinder often solves the issue of restoring the machine's performance.
A certain stock of such hydraulic cylinders is constantly maintained in the warehouse of the Mashservice company for prompt service of our customers, since the sale of DZ-98 is one of our main activities. In our practice as a supplier, there are cases that even within the framework of a military order it was planned to buy a DZ-98 motor grader in Chelyabinsk from our company, which was recently implemented.
As spare parts, we supply high-quality hydraulic cylinders of the "Berezovskiy Mechanical Plant" from our Ural region. For this well-known manufacturer, we have been an authorized dealer for several years and keep in touch with him.
Diesel grader: YaMZ-238, other options, features
As in the case of any large special vehicle of domestic production, known in our market for more than a dozen years, the manufacturer tried several options during this period power plants... The most popular was the YaMZ-238ND2 engine with direct fuel injection and a turbocharging system (for the DZ-98V.1 with a scarifier), although the Cummins M-11S265 (USA) and U1D6-TK-C5 of the Ural Motor Plant were tested.
Diesels for various modifications of the grader are usually 4-stroke, 8-cylinder, V-shaped arrangement of cylinders, although there are other options. One of the characteristics of the YaMZ-238 and its modifications on a motor grader is the consumption about 0.15 kg of fuel for processing 1 m 3 of rock by the machine.
New additional equipment of a modern motor grader
The machine is constantly being improved - on the new motor grader they are already present in the optional equipment:
- a pump load control system to save fuel (the so-called -system);
- joysticks to control working bodies;
- the possibility of transferring the blade to the "floating" mode of movement;
- video camera for the rear working area;
- the Glonass system and many other accessories that improve the operator's work.
How much can you buy a DZ-98 motor grader
A modern car costs a lot: in 2018, you can buy a new DZ-98 motor grader for no less than 5.5-6 million rubles, depending on the configuration and accounting for the utilization fee. However, if the customer has a large amount of work for such equipment, all heavy earthmoving and planning operations that can be performed with its help more than pay off the cost of purchasing a DZ-98 grader.
In addition, the Mashservice company can offer and used after full restoration of the resource and with our guarantee... We have extensive experience in repairing machines that have been used by customers for several years. As a result, our client can get a special vehicle, fully checked and "tightened up" by specialists, after replacing worn-out units with new spare parts from our warehouse, for a couple of million rubles cheaper.
How our customers choose
If the customer wishes to purchase such a heavy-class earthmoving and planning machine, it is quite natural that no one makes a decision only on the basis of information about the price of the DZ-98 grader and its basic technical characteristics... Equipment of this level of cost is not sold "by catalog". A reasonable client may well be interested in, in addition to this:
- availability from our warehouse;
- the experience of our mechanics in the repair of such equipment;
- the number of machines already delivered by us;
