Analysis of tractor age and its development in Slovak Republic

摘要

The trend in quantitative state and wear degree of tractors in Slovakia during 1995, 1997 and 1999 were analysed. It was found that the increment of tractors rate in age category below 4 years was from 2.55% in 1995 to 4.16% in 1999. On the other hand, the increment of tractors older than 8 years was from 81.86% in 1995 to 92.28% in 1999. The average age of tractors ranged from 11.19 years in 1995 to 12.29 years in 1999. The age wear coefficient increases from 1.40 in 1995 to 1.54 in 1999. Based onthe results, it can be inferred that tractors in Slovakia are considerably worn and obsolete, thus, maintenance and repair must be improved.
