Abstract
The article presents the results of a study devoted to the operational and technological evaluation of the work of the trailed soil ripper PRP-5,6 "Titan" (manufacturer – Omsk Experimental Plant). The change in soil hardness depending on its moisture content and tillage depth was studied. The agrotechnical parameters of the technological process were determined, and the energy assessment of the K-744R4 tractor operation in combination with the PRP-5,6 ripper was given. The study took place in the fields of a peasant farm located in the Pavlograd district of the Omsk region. The data obtained show that in an undisturbed fallow field the greatest soil moisture is retained in the upper sod layer, which retains moisture and does not allow it to pass into the lower layers. At a depth of 20 cm, the moisture content of fallow soil is 8% lower than that of the cultivated soil. At a depth of 40 cm, the moisture levels level out. The maximum hardness of fallow lands is observed at a depth of 30 cm. In general, the change in soil hardness depending on the depth of cultivation is represented by a se cond-degree polynomial equation. It has been established that, in terms of traction and power performance, the K-744R4 tractor in combination with the PRP-5,6 ripper ensures stable performance of the technological process during autumn soil cultivation at a working depth of 22 cm at a speed of up to 9.05 km/h, and at a working depth of 31 cm at a speed of up to 5.54 km/h. The retention of stubble on the field surface reaches 61–66%. The unit's traction resistance increased by 12% at a working depth of 21 cm with a speed increase from 5.60 to 9.05 km/h. At a working depth of 31 cm with a speed increase from 3.90 to 5.54 km/h, it increased by 11%. The unit's hourly productivity at a working depth of 21 cm and a speed of 9.05 km/h was 5.06 ha/h, and at a working depth of 31 cm and a speed of 5.54 km/h, it was 3.10 ha/h. Specific fuel consumption was 36.1 kg/ha.
