TestThe test is based on the DLG Test Regulations "Spreaders for organic solids" and the German standard DIN EN 13080 "Manure spreaders; Environmental protection – Re-quirements and test methods" of February 2003.

Collection trays (50 x 50 x 10 cm) are arranged flush next to each other crossways to the direction of travel on the trial field in order to determine the lateral distribution. The spreader carries out altogether three passages through the measur-ing section. The amount of mate rial caught in the trays is weighed and

standing throughout the complete discharge of a load. The data are used to calculate the characteristic values of constant distribution rate, percentage elongation within the tolerance zone, cv at optimal over-lap and the optimal overlap.

Starting from the 50 % line of constant distribution rate, the cv value at optimal parallel tracking with the next load is determined.

The smaller the cv and the larger the tolerance zone, the better the distribution quality is.

used to calculate the basic spread-ing pattern for the unit area. The cv value for the lateral distribution defines the distribution accuracy for the area after further spreading passages (for tramline passages). It is evident from the resulting course of the cv values whether the admissible cv threshold is un-dercut and in what area the optimal working widths (lowest possible cv) are achieved.

To determine the longitudinal dis-tribution, the mass flow is meas-ured via continuous measuring of the axle and support loads when

Test results and individual assessments

10 t manure/ha

For a working width of 12 metres and a spreading rate of 10 t ma-nure/ha, a variation coefficient (cv) of 8.8 % was achieved. Figure 4 shows the basic spreading pattern (quantity distribution per passage) and the overall spreading pattern. The latter shows the final area coverage after further tramline passages.

Figure 5 shows the dependence of the variation coefficient on the working width in graphic terms. It is evident from the course of the cv line that the cv for working

widths of up to approx. 24 metres is below 20 %.For the longitudinal distribution, at a spreading rate of 10 t manure/ha a cv of 14.9 % was determined at optimal overlap. The percentage elongation within the tolerance zone here is 56.5 %.

30 t manure/haFor a working width of 12 metres and a spreading rate of 30 t ma-nure/ha, a variation coeffizient (cv) of 12.2 % was achieved. Figure 7 shows the basic spreading pattern (quantity distribution per passage) and the overall spreading pattern.

The latter once again shows the final area coverage after further tramline passages.

Figure 8 shows the dependence of the variation coefficient on the working width in graphic terms. It is evident from the course of the cv line that the cv for working widths of up to approx. 15 metres is below 20 %.

For the longitudinal distribution, at a spreading rate of 30 t manure/ha a cv of 16.0 % was determined at optimal overlap. The percentage elongation within the tolerance zone here is 41.7 %.

5 t compost/ha

For a working width of 13 metres and a spreading rate of 5 t com-post/ha, a variation coefficient (cv) of 18.2 % was achieved. Figure 10 shows the basic spreading pattern (quantity distribution per passage) and the overall spreading pattern. The latter shows the final area coverage after further tramline passages.

For the longitudinal distribution, at a spreading rate of 5 t compost/ha a cv of 20.3 % was determined at optimal overlap. The percentage elongation within the tolerance zone here is 66.0 %.

25 t compost/ha

For a working width of 13 metres and a spreading rate of 25 t com-post/ha, a variation coefficient (cv) of 17.4 % was achieved. Figure 13 shows the basic spreading pattern (quantity distribution per passage) and the overall spreading pattern. The latter once again shows the final area coverage after further tramline passages.

Figure 14 shows the dependence of the variation coefficient on the working width in graphic terms. It is evident from the course of the cv line that the cv is at its optimum for a working width of 14 metres and that for working widths of more than 15 metres it oversteps the 20 % threshold.

For the longitudinal distribution, at a spreading rate of 25 t compost/ha a cv of 12.0 % was determined at optimal overlap. The percentage elongation within the tolerance zone here is 49.3 %.

Final assessment

Test

11-220April 2012© DLG

On the basis of the DLG Test Regulations "Spreaders for organic solids", the manure spreader TSW 3140 Tandem from Ludwig Berg-mann GmbH Maschinenfabrik was tested for accuracy of manure dis tribution with target spreading rates of 10 t/ha and 30 t/ha and accuracy of compost distribution with target spreading rates of 5 t/ha and 25 t/ha in May 2011.

tribution qualities are also good (cv ≤ 20 %) at working widths of 25 to 28 metres.

The requirements made of distri-bution quality for spreading manure and compost in the DLG Test Regulations were satisfied and the DLG test label "DLG FokusTest Distribution Quality Manure and Compost 09/11" was awarded.

As regards the spreading of manure and compost, very good and good spreading qualities were achieved for working widths of 12 metres (manure) and 13 metres (compost).For manure, with a spreading rate of 10 t/ha, the variation coefficient up to a working width of 24 metres is below 20%, in other words at a good to very good level. For spreading 30 t manure/ha the dis-
