Investigation of 161 selected family farms show that annual use of tractors and machines is very low. It is 300- 500 hr/year for tractors and 5-40 hours machines. Also life time is long - in some case more than twenty years. It may be stated that the search for and development of different forms of mechanization is indispensable, as the mean age of the used machines being over 14 years indicates the necessity for their replacement in time, which is impossible, considering the income obtained by small farms.
