Rational use of Versatile 2375 tractor on the main soil tillage

The goal of the work is to substantiate rational trac- tion modes and parameters of Versatile 2375 tractor for zonal tillage technologies. The analysis of the state of the Russian and regional markets for high-capacity agri- cultural tractors, made on the model series of mobile power tools of 4k4b wheel formula of domestic produc- tion is carried out. In the structure of the renewal of the tractor fleet of rural commodity producers in the Krasno- yarsk Territory, the K-744R tractors of the Petersburg Tractor Plant CJSC and Versatile 2375 Rostselmash LLC amounted to 35 and 7 %, respectively. The Models and algorithm of stage-by-stage optimization of mass energetic parameters taking into account established constructional features and restrictions on traction and high-speed operating modes are developed for increase of efficiency of use of Versatile 2375 tractor in technolo- gies of tillage According to the results of simulation and experiment, optimal values of the specific gravity of the tractor for tillage operations of different groups were substantiated...
