OPTIMIZATION OF A SYSTEM FOR DRAFT-POSITIONAL CONTROL OF MOUNTED AGRICULTURAL IMPLEMENT

  • 1 ИПАЗР "Никола Пушкаров" – София, България

Abstract

The three-point linkage of Bulgarian middle power wheeled tractors "Bolgar" is equipped with a control system that allows only draft or positional control of mounted implement, which limits the effective use of tractors in the agricultural production.

The article presents results of a study on optimization of the parameters of a control system that provides mixed adjustment. Different variants of new develop lever mechanism which sums the control signals for draft and positional adjustment were analyzed and the most appropriate for practical realization was chosen. Experimental verification was carried out in field conditions, which confirmed the improved functional properties of the optimized design solution and appropriateness for implementation in agricultural practice
