A test mark “DLG-APPROVED for individual criteria“ is awarded for agricultural products which have successfully fulfilled a scope-reduced usability testing conducted by DLG according to independent and recognised evaluation criteria. The test is intended to highlight particular innovations and key criteria of the test object. The test may contain criteria from the DLG test scope for overall tests, or focus on other value-determining characteristics and properties of the test subject. The minimum requirements, test conditions and procedures as well as the evaluation bases of the test results will be specified in consultation with an expert group of DLG. They correspond to the recognised rules of technology, as well as scientific and agricultural knowledge and requirements. The successful testing is concluded with the publication of a test report, as well as the awarding of the test mark which is valid for five years from the date of awarding.
The DLG test for the distribution quality of livestock manure was carried out using the BRANTNER TA 24078 POWER-SPREAD pro Universal Spreader with CSP2-2 Universal Spreading Unit. The 2-plate spreader is equipped with two horizontally mounted milling rollers. The distribution quality was measured at application rates of 10 t/ha and 30 t/ha with livestock manure. The cattle manure used had a dry matter content of 19.4 % and a bulk density of 726 kg/m³. The transverse and longitudinal distribution were determined in each case.
Other criteria were not reviewed.
Assessment in brief
For livestock manure with spreading rates of 10 t/ha and 30 t/ha, the DLG test achieved very good (+ +) and good (+) spreading qualities in the transverse direction as well as good (+) results in the longitudinal direction. Table 2 shows a summary of the results.

The method
The test is based on the DLG test framework “Spreaders for organic solids“ and the standard DIN EN 13080 “Manure spreaders – Environmental protection – Requirements and test methods“.
To determine the transverse distribution, collection containers (50 cm x 50 cm x 10 cm) are placed flush with each other across the test area, perpendicular to the direction of travel. The tractor then drives through the measuring section with the spreader to be tested. The quantities of spreading material collected in the trays are weighed and calculated on an area basis to determine the basic spreading pattern. The quality of distribution is described by the coefficient of variation (CoV). The CoV value for transverse distribution indicates how evenly the area is covered, taking into account the overlap after further connecting runs. The CoV values show when the permissible CoV threshold is undershot and in which range the optimum working widths (lowest possible CoV) lie.
To determine the longitudinal distribution, the mass flow is measured by continuously recording the weight of the cargo area while stationary during the complete emptying of a load. This is used to calculate the characteristic values: characteristic manure application during unloading, dilation within the tolerance zone (percentage of the unloading time during which the application rate is within the permissible tolerance), the optimum overlap of the connecting journey and the CoV with optimum overlap.
The smaller the CoV and the larger the tolerance zone, the better the distribution quality.
The test results in detail
Test
The test was conducted in August 2025 on a harvested wheat field in the Niederösterreich region of Austria. Figure 2 shows the mobile test bench for measuring transverse distribution with collection trays. Figure 3 shows the unloading of the tested spreader in a stationary position to determine the change in mass during the unloading process.
To determine this parameter, the weighing cells installed on the spreader were used, which had been validated by the DLG Test Center prior to the test. The cattle manure used had a dry matter content of 19.4 % and a bulk density of 726 kg/m³ DM. A John Deere 7310 R was used as the tractor during the test. The spreader was loaded using a telescopic loader.
Adjustment
The spreading quantity of the BRANTNER TA 24078 POWER-SPREAD pro is determined by the feed rate of the transport base, the opening height of the damper valve and the driving speed of the tractor. The transport base speed can be varied continuously from 0.2 to 5 metres per minute. The transport base is hydraulically driven. The opening height to the spreading unit can also be adjusted continuously on the control terminal using the damper valve. With the damper valve with position measuring system, the opening height is preset on the ISOBUS terminal and the damper valve is moved to the preset height at the touch of a button. The current height is displayed in the terminal and used for control purposes. On spreaders without ISOBUS equipment, the opening height is shown to the driver by means of a display (with a scale from 0 to 1.6 metres) on the front panel of the spreader (Figure 5).
The entire spreading unit of the BRANTNER TA 24078 POWER-SPREAD pro is driven by the PTO shaft (max. 1,000 rpm). The spreading material is distributed transversely to the direction of travel by two spreading discs (Figure 6). Each spreading disc is equipped with six swivelling spreading vanes. Seven different opening angles can be set on each spreading vane.
The opening angle is adjusted manually. To do this, the operator loosens the screw connection of the spreading vane (M16) on the inside of the spreading blade. Then the shear bolt (M12) on the outside of the spreader blade is removed. The spreading blade is then moved into the desired position (there are seven holes for each spreading vane) and secured and tightened again with the M12 shear bolt. Finally, the screw connection of the spreading vane is locked again. The operating instructions provide the operator with information on how to adjust the spreading vanes for various spreading materials.
The so-called foreign object flap can be used to adjust the feed point of the spreading material to the spreading discs. The foreign object flap is adjusted lengthwise (feed point) manually after loosening the lock nuts by adjusting the stop screws (M16). The height of the scraper bar above the spreading discs can also be adjusted. After loosening the screw connection (M12), a hand lever provided can be used for manual adjustment. The hand lever has a fixed location on the loading wall.
Information on the basic settings depending on the spreading material and the desired spreading quantity is also provided in the operating instructions. Due to the very different material properties of the various spreading materials, it is advisable to check the spreader settings during a test run and optimise them if necessary.
Transverse and longitudinal distribution with livestock manure
For an application rate of 10 t/ha, at a driving speed of 5.0 km/h, as well as other setting parameters and material properties, the automatic ISOBUS-controlled application rate control regulated a feed rate of approx. 0.8 m/min. In the third test, a spreading quality with a coefficient of variation (CoV) of less than 20 % was achieved at working widths of up to 17 metres.
Figure 7 shows the basic spreading pattern (quantity distribution after four passes) and the overall spreading pattern (quantity distribution taking overlaps into account) for an application rate of 10 t/ha of livestock manure.
Figure 8 shows the dependence of the coefficient of variation on the working width for an application rate of 10 t/ha of livestock manure. The CoV curve shows that the CoV has a value of 8.6 % (very good, + +) at a working width of 14 metres. For a working width of 15 metres, the CoV has a value of 11.8 % (good, +). At 17 metres, the coefficient of variation exceeds the 20 % line.
For an application rate of 30 t/ha, at a driving speed of 3.0 km/h, as well as other setting parameters and material properties, the automatic ISOBUS-controlled application rate control regulated a feed rate of approx. 1.5 m/min. On the third attempt, a spreading quality with a coefficient of variation (CoV) of less than 20 % was achieved at a working width of 27 metres.
Figure 9 shows the basic spreading pattern (quantity distribution after two passes) and the overall spreading pattern (quantity distribution taking overlaps into account) for an application rate of 30 t/ha of livestock manure. Figure 10 shows the dependence of the coefficient of variation on the working width for an application rate of 30 t/ha of livestock manure. The CoV curve shows that the CoV has a value of 10 % (very good, + +) at a working width of 11 metres. For a working width of 25 metres, the CoV has a value of 14.4 % (good, +). Only at 27 metres does the coefficient of variation exceed the 20 % line.
To evaluate the distribution quality in the longitudinal direction, the calculated coefficients of variation reach values of 11.8 % for 10 t/ha of livestock manure (good, +) and 11.6 % for 30 t/ha of livestock manure (good, +). The dilation within the tolerance zone was 66.8 % (good, +) for 10 t/ha of livestock manure and 72.9 % (good, +) for 30 t/ha of livestock manure.
Figures 11 and 12 show the results for longitudinal distribution.
In the DLG test, the BRANTNER TA 24078 POWER-SPREAD pro Universal Spreader with CSP2-2 Universal Spreading Unit was tested for spreading livestock manure (10 and 30 t/ha). The coefficients of variation determined for the evaluation of the transverse distribution are all below 20 %. The transverse distribution of 10 t/ha of livestock manure is rated as very good (+ +) with a working width of 14 metres and good (+) with a working width of 15 metres. The transverse distribution for a application rate of 30 t/ha of livestock manure and the corresponding working width of 11 metres is rated as very good (+ +) and with a working width of 25 metres as good (+).
The results achieved in the DLG test for longitudinal distribution with livestock manure for application rates of 10 and 30 t/ha were rated as good (+) without exception. For an application rate of 10 t/ha, the dilation within the tolerance zone is 66.8 % (good, +) and the coefficient of variation with optimal overlap is 11.8 % (good, +). For an application rate of 30 t/ha, the dilation within the tolerance zone is 72.9 % (good, +) and the coefficient of variation with optimal overlap is 11.6 % (good, +).
Information on the basic settings depending on the spreading material and the desired spreading quantity can be found in the operating manual. Due to the very different material properties of the various spreading materials, it is advisable to check the spreader settings during a test run and optimise them if necessary.
Based on the available results, the BRANTNER TA 24078 POWER-SPREAD pro Universal Spreader with CSP2-2 Universal Spreading Unit is awarded the DLG-APPROVED test mark for the 2025 sub-test “Livestock Manure Distribution Quality“.
