RT Journal Article SR Electronic A1 Brožek, Milan T1 Technical-economical evaluation of the overlays application on the plough shares JF Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis YR 2014 VO 55 IS 4 SP 129 OP 136 DO 10.11118/actaun200755040129 UL https://acta.mendelu.cz/artkey/acu-200704-0016.php AB The paper presents the performance tests results of plough shares without and with overlays. During the tests the relationship between the single plough shares wear and the plough operation time was watched. Using the in this way determined time behaviour of wear and the basic economical materials the average renovation and operation costs for each used plough share were calculated. Using this criterion it is easy to compare single technical-economical solutions.
