摘要：

The aim of the investigation was to compare and unveil efficiency Of, electro-hydraulic control (EHR) system to mechanical three point hitch regulation in mouldboard Ploughing. Increase of working velocity and three point hitch automatic regulation activity decreased depth of Ploughing at both regulation systems but electro-hydraulic system done it more accurately since deviation from default value was 10% less than at mechanical regulation system. Electro-hydraulic three point hitch control system decreased wheel slip up to 30 % in comparison to mechanical regulation system. Net energy requirement at mechanical three point hitch regulation system spent 3 %, more energy than electro-hydraulic control system. If wheel slip reduction influenced by electro-hydraulic control system would be added one could account on greater energy savings than previously mentioned value. The greatest working rates were achieved at the greatest working velocity (8,0 km h(-1)), while exactly at that velocity the greatest working rate increase of 3,8 %, influenced by electro-hydraulic three point hitch control was noticed.
