From the point of view of energy saving, research into agricultural gantry units equipped
with new implements specially adapted for operation in such systems and capable of efficiently
functioning in controlled traffic (permanent lane) and wide span (gantry) systems is an important
and topical issue in soil tillage science. The range of wide span systems includes harrowing units
for fallow land tillage. This paper describes the experimental determination of the operating
characteristics of the harrowing unit, in which a gantry implement carrier propels harrows for fallow
land tillage, for the purpose of establishing the compliance of their parameters with the fundamental
principles of the effective implementation of the controlled traffic and wide span soil management.
The experimental investigations were done using strain-gauge and control-and-measuring
equipment with analogue-to-digital conversion of the signals received from the sensing elements.
An agricultural wide span unit with a track width of 3.5 m and harrows for fallow land tillage were
investigated. The results show the harrowing unit is well adapted to operation in controlled traffic
and wide span soil tillage systems and delivers high quality performance of the harrowing process.
The latter effect is also due to the fact that the gantry travels on the compacted tracks which have a
few surface irregularities compared to cultivated soil. The coefficient of variation of the draught
force applied to the hook of the gantry during harrowing operations did not exceed 10%. This is
evidence of the high stability (low variability) of the harrowing process, which has a positive effect
on the motion stability of the harrowing unit based on the gantry tractor.
