Waterworks
The pressure potential for system operation is created by a variable displacement pump (Model A10NC045/52R-XRC07H503D-S1958) with volumetric flow at a nominal diesel crankshaft speed of -115 l/min. The system distributor is four-sectional with built-in working fluid flow regulators in each section. The spools are fixed in the floating and neutral positions. The spool of the first section additionally has the function of fixing in the rise position with automatic return to the neutral position.
Distributor Controls
Tractor hitches
The rear linkage is equipped with two hydraulic lifting cylinders Ts110X250. The lifting capacity of the hitch on the suspension axis is 10 tons.
Front linkage with two hydraulic lifting cylinders Ts90x250. The load capacity on the hanging axle is 5 tons.
For connection with trailers and trailed vehicles, the rear linkage is equipped with a hook with a shock absorber - TSU-3K. TSU-2 fork - for connection with semi-trailer transport and technological machines. TSU-1M-01 for aggregation with trailed machines.
Application area
The main use of a tractor of the fifth traction class is to perform agricultural work on large areas of land.
The efficiency of the machine in performing these works is ensured by the possibility of its aggregation with mounted wide-cut mechanisms with large load capacity and high productivity, including foreign-made equipment - Super Rapid 400C and Amazone seeding complexes and the DISCO-8500 mower manufactured by CLAAS.
Layout and ergonomics
The traditional layout for Minsk-made tractors - a cabin located behind the power plant, which does not impede access to the engine during repair and maintenance, and large wheels - are combined with a modern design that emphasizes the power of the machine, making the MTZ-2522 attractive and recognizable.
The tractor cabin is equipped with a reinforced frame that meets the requirements of international standards, ensuring operator safety when the machine overturns.
Systems for heating and cleaning the air entering the cabin, air conditioning, opening windows, a large volume of glazing, electric washing equipment for the front and rear windows, a sunroof built into the roof, a swiveling driver's seat, two control stations with highly ergonomic instrument panels create maximum conditions for comfortable and productive work. operator.
Pneumatic system
The equipment is designed to drive air brakes of trailed vehicles and machines, as well as to extract compressed air when servicing the tractor.
The tractor is equipped with a compressor with liquid heat exchange of the working cylinder - from the diesel cooling jacket. The safety valve limits the pressure in the pneumatic line within 0.85 - 1.0 mPa (8.5 - 10 kgf/cm²). The regulator maintains the operating pressure in the system within 0.65 - 0.8 MPa.
