This European Standard consists of the following parts under the general title Agricultural machinery Solid fertilizer broadcasters and full width distributors Environmental protection: Part 1: Requirements Part 2: Test methods Annex A is informative. This document includes a Bibliography. 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. Licensed Copy: sheffieldun sheffieldun, na, Mon Oct 30 01:59:24 GMT+00:00 2006, Uncontrolled Copy, (c) BSI EN 13739-1:2003 (E) 4 Introduction The objective of this European Standard is to specify requirements for fertilizer distributors used according to the instruction handbook, so that: unintentional spreading of fertilizers is avoided; an even distribution of fertilizer with the desired application rate is achieved. This 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 full width solid fertilizer distributors and solid fertilizer broadcasters used in agriculture and horticulture. It also gives the requirements for the minimum content of the instruction handbook. The standard does not apply to machines which are: combined grain and fertilizer drills; or equipment for distributing granulated pesticides; or solid fertilizer line-distributors (which are dealt with in prEN 13740-1 and in prEN 13740-2). 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 full width distributors and broadcasters, except in the terms and 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 apply (including amendments).

The machine shall fulfil at least the requirements given 4.2 up to 4.13. NOTEThe manufacturer should also take into 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 the distribution spreading pattern in a negative way. This can for example be achieved by a grid. 4.3 Cleaning and emptying of residuals Emptying and collecting the fertilizer from the hopper shall be possible without spreading 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 On a full width distributor fitted with a boom 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 full width 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 way without being damaged (see Figure 2). The boom sections shall return automatically to their original position after contact with the obstacle.

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. 4.6 Adjustment of flow rate 4.6.1Machines with a hopper volume of 600 l or more, shall either be equipped with: relevant calibration aids (for example chute, guide, collector) to adjust the flow rate; or a system which controls the flow rate automatically (for example load-sensor, mass flow control). 4.6.2If the machine is fitted with a manually controlled system which allows a variation of the flow rate, then this variation range shall be at least ± 20 % of the intended flow rate, but shall not exceed the limit values defined in 4.13. 4.6.3It shall be possible to make the adjustment stepless or in steps of maximum 10 % of the intended flow rate.
