Tractor

UMZ-8244.2М
General purpose tractor has power 80 hp with front braced type axle from Italian company "Carraro" – world leader in the sphere of designing and production of tractor’s transmission, road-building engineering and machines, loading engineering. 

Technical features of the model: 
 strengthened transmission; 
 strengthened mechanism of a hydraulic hitch system; 
 automatic unifying PPC transfer box; 
 strengthened half-frame with heightened safety factor of axle drive gear; 
 operating speed – from 1,62 to 11,57 km/h, transport speed up to 35,33 km/h; 
 heightened vehicle capacity with allowable load to the front axle up to 2 t. 

Application areas: 
 agriculture;   
 community facilities; 
 forestry; 
 building; 
 industry. 

Due to establishing capacity of special purpose with changeable operating parts this tractor become the universal road building and digger machine operating as an excavator, bulldozer, loader. 

Tractors under the UMZ brand could operate both at the temperate and tropical climate.
