Influence of top link length of three-point hitch on performance parameters of ploughing set

Abstract

The target of the realized measurement was to subject the influence of top link on wheel slip and performance and economic parameters of ploughing set. To meet the objectives the set of New Holland 7050 tractor aggregated with plough Kuhn Variomaster 150 was used during field work. Parameters of internal systems were monitored via CAN-Bus, e.g. engine speed, fuel consumption, fuel temperature, atmospheric pressure, intake air temperature, time of trip, etc. Additional external measurement consisted of a signal of rear wheels rotation and signal of radar sensor for slip determination. Load cell sensor HBM was mounted into a top link. The values of slip were reduced when the top link length decreased. A change of wheel slip from 16.6% to 11.2% caused by reduction in length brought improvement in performance up to 16.5% and effective fuel consumption per hectare lowered about 18.1%.
