This European Standard consists of the following Parts under the general title Agricultural machinery Solid fertilizer line-distributors Environmental protection: Part 1: Requirements Part 2: Test methods Annex A is informative. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Slovakia, Spain, Sweden, Switzerland and the United Kingdom.

This European Standard does not include any direct requirements for the longitudinal distribution. The requirements for evenness of flow rate will partly cover that subject. 1 Scope This European Standard specifies requirements for the environmental protection for design and construction of mounted, trailed and self-propelled solid fertilizer line-distributors, including such machines attached to a basic machine, used in agriculture and horticulture. It also gives the requirements for the minimum content of the instruction handbook. NOTEThe standard is also applicable to seed drills if it is stated by the machine manufacturer that the machine is suitable for fertilizer application. This standard does not apply to machines which are: equipment for distributing liquid fertilizer; or equipment for distributing liquid or granulated pesticides; or solid fertilizer broadcasters and full width distributors (which are dealt with in EN 13739-1 and in EN 13739-2). Personal safety aspects have not been considered in this standard; they are dealt with in prEN 14017. If the term “machine“ is used, it covers both drilling and spreading line-distributors, except in the definitions. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revision of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies (including amendments).

The machine shall fulfil at least the requirements given in 4.2 up to 4.14. NOTEThe manufacturer should also take in consideration that the machine may work in a corrosive environment. 4.2 Hopper filling opening The machine shall be designed to minimize the risk that undesirable materials will cause blockages and influence the flow rate or transversal distribution in a negative way. This can for example be achieved by a grid. Hoppers with a volume equal to or greater than 1 000 l shall be so constructed that it is possible to fill the hopper with bulk fertilizer from a bucket, 1,5 m wide or from big bags of 1 000 kg. 4.3 Cleaning and emptying of residuals Emptying and collecting the fertilizer from the hopper shall be possible without spreading or drilling and without unintentional flow to the ground. If tools are necessary to empty the hopper, they shall be delivered with the machine and a place shall be provided on the machine for their storage. It shall be possible for a person standing on the ground or on the existing access means to clean the machine. 4.4 Contact with obstacles 4.4.1 General On a spreading line-distributor fitted with booms with a working width more than 10 m, the outer end of the boom shall be able to move backwards in case of contact with obstacles in the field. If the spreading distributor is moved forwards at 8 km/h and the obstacle is within 90 % to 100 % of half the boom width measured from the middle of the track, the boom or sections of the boom shall be able to give away without being damaged (see Figure 1). The boom sections shall return automatically to their original position after contact with the obstacle.

The working depth of the coulters shall be adjustable. 4.5 Marker system Combined drills wider than 4 m, for drilling fertilizer into the soil, shall be equipped with a marker system which gives the possibility to choose correct distance to next tramline. 4.6 Estimation of hopper volume The basic-hopper of the machine (e.g. the hopper without any extension walls), shall be fitted with a scale in litres by which the volume of fertilizer in the hopper can be determined. In case of an adjustable partition wall of the hopper (for example in combined drills), the hoppers shall be equipped with scales to indicate the actual volume hopper with different adjustments at each position of the partition wall. The scale shall cover at least 10 % to 80 % of the basic-hopper volume and have a graduation for at least each 10 % of the nominal volume of the basic- hopper. The accuracy of the graduations shall be within ± 10 % of the reading.

The adjustment of the feeding system with fertilizer of type a) as defined in 4.2 and 4.3 of EN 13740-2:2003 shall occur within 5 s when adjusting the flow rate from flow rate 3 by ± 50 %, but shall not exceed the limit values defined in 4.13.1. 4.9 Adjustment for working width For machines where the working width can be altered it shall be possible to adjust the machine to a different working width (for example to a reduced wo
