Single seed drills
Single seed drills must adhere to additional requirements beyond those specified in section 5.4.2 Specifically, the power transmission components driven by ground wheels must be shielded on the outer side of the outer seeding units If the seeding units are interchangeable, the instruction manual must clearly state that only those units equipped with covered power transmission parts are to be installed on the exterior of the seed drill.
Inspection is required to verify compliance with safety standards Specifically, any drive components, such as shafts, pinions, and drive chains, positioned within 850 mm of the machine's outer edges or the platform must be adequately guarded to prevent risks of drawing-in, trapping, or entanglement hazards.
This shall be verified by measurement See also 7.1 h).
Blower
A seed drill equipped with a blower must have the blower positioned or shielded to prevent the intake or release of foreign materials that could harm the operator during operation This safety measure should be confirmed through inspection.
The blower's actuation and intake area must be protected by fixed guards, which may consist of a combination of mesh and imperforated materials Furthermore, it is essential to adhere to the safety distances specified in Tables 1, 3, and 4.
Flow rate calibration system
A seed drill equipped with a flow rate calibration system allows operators to conduct calibration tests and monitor seed flow without needing to go underneath the machine during operation This feature must be confirmed through inspection.
Hitching and clearance zone
To ensure proper functionality of mounted machines, it is essential to maintain adequate clearance between the machine and the tractor, as well as between the machine and the soil working machine This clearance is necessary for the connection of driving elements, such as the transmission, and steering elements, including electric or hydraulic remote controls.
To facilitate the connection of driving and/or steering elements after coupling the seed drill, it is essential to increase the clearance zone shown in Figure 6 on at least one side.
design of the driving and steering elements so that their connection is possible before coupling the seed drill in a comparable clearance zone according to Figure 6

Noise reduction as a safety requirement
5.10.1.1 Reduction at source by design and by protective measures
The machine shall be designed to generate a noise level as low as practicable The main sources causing noise are:
blower (applicable only for pneumatic machines);
Machines shall be designed and constructed taking into account the available information and technical measures to control noise at source at the design stage, as described in EN ISO 11688-1
NOTE EN ISO 11688-2 gives useful information on noise generation mechanisms in machinery
If a manufacturer deems additional operator protection necessary after implementing all feasible noise reduction measures during the design phase, they must provide sufficient information in the instruction manual.
Verification of requirements on noise based on noise emission values
To determine the sound power level and the emission sound pressure level at the operator's position, the noise test code specified in EN 1553:1999, Annex D must be utilized.
6 Verification of the safety requirements and/or protective measures
The requirement of 5.3.1 shall be verified by measurement as follows: the height of 4 m shall be measured with machine on horizontal level ground
Instruction handbook
The manufacturer shall provide detailed instructions on machine maintenance and safe usage in the instruction handbook, including guidelines on appropriate clothing, personal protective equipment (PPE), and necessary training For additional guidance on drafting the instruction handbook, refer to section 5.5 of EN ISO 12100-2:2003.
In particular the following points shall be emphasised (residual risks): a) hazards resulting from a combination, association or coupling of equipment, in particular with soil working machines (see 5.2);
When operating the machine, it is crucial to ensure that no one stands nearby while it is in motion, particularly due to hazards associated with contact with markers Safe procedures must be followed for adjustments, calibration, and loading Additionally, operators should refrain from wearing loosely fitting clothing to prevent entanglement with moving parts.
It is essential to wear personal protective equipment (PPE) when required, as outlined in section 5.8 Additionally, attention must be given to the hazards associated with the removal and refitting of seed units, along with the specific handling instructions that must be adhered to for safety.
When operating machinery, it is essential to use a PTO drive shaft with a properly maintained guard to ensure safety To prevent blockages, avoid using damp seed and be aware of the hazards associated with clearing blockages, particularly those caused by incorrect machine lowering A thorough risk assessment is necessary to mitigate the risk of accidental contact with overhead power lines, especially in uneven terrain or when using movable components Additionally, it is crucial to verify that the unlocking procedure does not lead to uncontrolled movement of swivelling components, particularly with new machines Lastly, ensure that the appropriate seed units are fitted on the outside of the machine when using interchangeable seeding units.
Instructions for the use of automatic and semi-automatic hitching should be followed, along with guidelines for manual handling of heavy loads and proper sack handling techniques Additionally, users must refer to the instruction handbook and technical documentation provided by the manufacturer for comprehensive information about the machine.
give the declared noise emission values of the machinery as follows:
the A-weighted sound pressure level at workstations, where this exceeds 70 dB Should the sound pressure level not exceed 70 dB, this fact shall be indicated;
the peak C-weighted emission sound pressure level at workstations, where this exceeds 63 Pa
(130 dB in relation to 20 àPa);
the A-weighted sound power level emitted by the machine where the A-weighted emission sound pressure level at any workstation exceeds 85 dB;
give reference to the noise test code specified in Annex D of EN 1553:1999;
recommend the use of low-noise operating modes, and/or limited time of operation, if necessary;
give a statement of the noise level and recommend the use of ear protection, if necessary

that it is dangerous to ascend onto the machine while it is moving; this warning is to be affixed near the means of access, if any;
hazards caused by moving parts (hopper)
Examples of pictograms are given in Annex C
Stability of the tractor-seed drill combination
This annex pertains to section 7.1 r), which mandates the provision of information regarding the potential loss of stability of the tractor when connected to the seed drill.
The following text is a suggestion to the manufacturer to enable him to provide adequate and complete information
The example suggested refers to a seed drill mounted on a tractor
The tractor-seed drill combination can experience instability due to the weight of the machine and the materials in the hopper To ensure total stability, it is essential to calculate the minimum front ballasting, denoted as \( I_{F,\text{min}} \), which ensures that the weight on the front axle is adequate.
20 % of the unladen weight of the tractor: b a b T 0,2 b T d c
NOTE Rear mounted implement and front/rear combinations are considered for this calculation
T E [kg] Unladen weight of tractor n
T F [kg] Front axle load of unladen tractor n
T R [kg] Rear axle load of unladen tractor n
I R [kg] Combined weight of rear mounted implement/rear ballast o
The combined weight of the front-mounted implement or front ballast is denoted as \( F \) [kg] The distance from the center of gravity of this combined weight to the front axle center is represented as \( a \) [m] The tractor's wheelbase is indicated by \( b \) [m], while \( c \) [m] refers to the distance from the rear axle center to the center of the lower link balls Additionally, \( d \) [m] measures the distance from the center of the lower link balls to the center of gravity for the combined rear-mounted implement or rear ballast For further details, please consult the tractor's instruction handbook and the price list or instruction handbook of the implement Measurements should be taken as specified.
