Summary: Vibrations by tractor aggregates occur when a power generating machine is in work, bacause of connecting machines and equipment or uneven agricaltural acreages. Vibrations are transfered from tractor on a driver's body which is not adequatly protected of their negative influence. For temporal estimation of exposure of human body to vibrations, certain references (for example ISO 2631) for only one direction are in use. By this project the levels of vibrations would be established on the seat and on manual and pedal steering commands, by agritechnical operations and by transportations in agriculture. For certain operations rations where the level of vibrations in all three directions is approximately of the same dimensional order, suitable proportions of combinations of these vibrational levels would be difined and the references would be supplemented. The problem of rotative vibrations around mentioned directions would be considered.

Keywords: vibrations, tractor, driver

Research goals: To establish by measuring the level of vibrational loading of a driver in the area of seat and organs (arms and legs) leaned on steering-wheel commands for usual tractor aggregates while performing agritechnical operations and transportation in agriculture. To elaborate the results of measuring and to compare them to the standard references. It is expected by certain agritechnical operations and certain connecting machine that the level of vibrational loading in all three directions (back-chest, left-right side, legs-head) would be nearly of the same order of dimensions. To find out suitable proportions of combinations on the levels of vibrations and to supplement the references which are valid so far for merely one direction. To analyse the occurance of rotative vibrations around afore mentioned directions and to estimate their influence on a driver since the existing standards do not mention them at all. This research should be used as a base for optimalization of driver's work place from the point of view of minimization fo vibrations and for redefining technological velocities of agritehnical operations and limitations of a lenght of working hours with occasional breaks.
