A team representing Kverneland, Versatile and Traction magazine – the farm machinery
Magazine – has ploughed 24 hours non-stop with just one full tank of fuel.
A 550 DeltaTrack belt tractor and a 12 furrow Kverneland PW Variomat, with Packomat,
completed an overall acreage of 103,5 hectares. Working depth had been adjusted to 26 cm on medium-heavy soils (loamy to clayey sand).
“Versatile DeltaTrack can use 1.700 l of fuel storage and is therefore one of the tractors
with the biggest tank capacity on the market”, explains André Duenk, Product Specialist at
Stoevelaar Machinery BV, the Dutch importer of Versatile.
“Based on this, standstills for refuelling were minimized and several shifts could be worked in a row. In addition, the Tier 4i homologated Cummins QSX15 engine runs very efficiently as its maximum torque is available at fairly low 1.400 rpm. 550 hp nominal and 591 hp maximum in combination with 2.779 Nm maximum torque ensure sufficient power reserves under all conditions”.
“Kverneland focuses on efficient ploughing for the farmer”, says Dominik Haselhorst, Manager Marketing and Product Management at Kverneland Group. “Hence, this experiment has been a good opportunity to prove that our ploughs are easy to pull“.
Haselhorst highlights three main aspects of the plough: “The entire implement is operated via ISOBUS from the tractor cabin, ensuring smooth turning sequences on the headland, this also relieves the operator during long working days. The plough centerpiece is body N° 28 – providing wide and empty furrows as well as burying organic matter properly. This type of universal plough body generates low pulling forces. In addition to quality ploughing, special attention was given to levelling and re-compacting throughout the entire soil depth with the plough integrated Packomat. Because of this a seedbed was practically prepared in one pass”.
Maximum acreage was not the objective of the task best practice was judged to be far more important.
“The results are clear for every farmer”, explains Traction’s chief editor
Matthias Mumme. “
After harvesting, corn stubble and residues had just been mulched once. “We didn’t choose extremely light conditions, usually chosen for record ploughing, neither had the soil
been worked with a cultivator or disc harrow prior to ploughing.
Also the headlands had not been laid out extraordinary wide”, says Mumme. “Due to the previous long dry spell and wet layer of residues on top of the soil, conditions have been demanding. Not least, compact headlands resulted in comparably long reversing sequences.
The 24-hour ploughing was carried out in two fields of APH e.G. Hinsdorf in
Quellendorf, Saxony-Anhalt. One of the plots was a triangular shape and caused a higher
degree of unproductive headland driving. Despite the expected reduced traction due to the
mulch layer, the team decided to use the PW 100 Variomat driving On-land.
Four, 76 cm wide Camoplast rubber tracks grant extensive gearing between tractor and soil under nearly all conditions which reduced slippage to a minimum.
Both Auto-steering of the tractor and recording of the ploughed acreage were measured by using a FarmRTK-guidance system by AXIO-NET. Metering the fuel tank of the Versatile 550 DeltaTrack after ploughing showed an overall diesel consumption of 1.664 l, equivalent to about 16 l per hectare.
“Based on current conditions, we are very satisfied,” Dominik Haselhorst summarizes. “The soil has been quite tricky to work. The plots were partly sloped and 26 cm working depth has even been slightly deeper than usually on this farm”.
All in all, the 12 furrow PW 100 Variomat offered a working width of 6,0 m – having been
pulled by the Versatile 550 DeltaTrack with an average speed of 9,3 km/h.
“All three team members, namely Kverneland, Versatile and ‘traction’ did an excellent job. The plough left a levelled and re-compacted, well-crumbled seedbed without residues – and also working with the Versatile DeltaTrack has been very convincing. Its even high torque throughout a wide range of speeds is impressive and allows the engine to be operated at lower rpm rates even under full load in order to save fuel”, added Haselhorst.
