One of the promising ways of efficiently applying high power intensity tractors is their design and utilisation in the form of modular traction vehicles comprising […]
Theoretical research into the stability of motion of the ploughing tractor-implement unit operating on the ‘push-pull’ principle
The reduction of power consumption in the ploughing operations can be achieved by way of improving the grip properties of the implement-carrying tractors, which is […]
Theoretical research into the motion of combined fertilising and sowing tractor-implement unit
A mathematical model has been developed representing the motion of a seed drill combination simultaneously performing the preceding banded placement of mineral fertilisers. Such a […]
The action of force measurement for the three-point hitch of a tractor
The object of the executed measurements which were carried out was to obtain time courses for the forces and pressures inherent in a hydraulic system […]
Monitoring oil degradation during operating tests
This paper deals with a lifetime test of the hydraulic and transmission oil, Shell Spirax S4 ATF (Universal Tractor Transmission Oil (UTTO)). This fluid was […]
Theoretical research into the frictional slipping of wheel-type undercarriage taking into account the limitation of their impact on the soil
The frictional slipping of the tractor’s wheels causes great damage to the soil fertility. To ensure the minimal disturbance of its structure, it has been […]
Light tractor simulator
A tractor simulator was made for hard tillage work. The aim of the simulator was to have it in national language and that it is […]
Specific Features of Establishment and Maintenance of Tractor Fleet in a Typical Estonian Agricultural Holding
In spite of the high reliability of modern tractors, they are no perpetuum mobiles and need at times designated by the manufacturer’s technical condition regular […]
