Abstract. The physical degradation of soil due to the interaction with the<br />

active parts of the agricultural units and with the wheels of the agricultural units<br />

consists mainly in the deterioration of its structure and also in its compaction. In<br />

order to quantify these aspects, experimental studies should be developed to<br />

establish the values of the active parts and wheels’ working parameters lea<strong>din</strong>g<br />

to soil degradation. A laboratory test rig with soil bin was designed and built in<br />

order to perform studies regar<strong>din</strong>g the interaction of agricultural machineries<br />

active parts and wheels with the ground. The studies carried out on the rig allow<br />

the determination of the working parameters for the active parts and the wheels<br />

(forces of resistance, slip etc), and their impact on the physical and mechanical<br />

properties of soil.<br />

Key words: active parts, wheel, soil channel.<br />

1. Introduction<br />

The interaction of the active parts and wheels of the agricultural<br />

equipments with the ground determines its physical degradation, in particular by<br />

compaction, but also through the deterioration of its structure (Căproiu et al.,<br />

1982; Jităreanu et al., 2007; Ţenu et al., 2010). Experimental studies are<br />

necessary to quantify these aspects, in order to establish the values of the active<br />
