• First, the space for the lawn should be freed of all vegetation, stones and non-degradable
material.
• Make sure that tree roots are removed and any pits levelled.
• Next, the upper soil layer (15 to 20 cm) is loosened thoroughly, for instance by aeration or deep
dethatching.
Caution:
Freshly ploughed soil may contain foreign objects.
• It is then mixed with organic material, if possible, such as compost.
• After fertilising, the soil is finely tilled with a cultivator so that the fertiliser is mixed well into
the soil and the coarser clods pulverised.
• The surface is level and does not contain bumps bigger than 150 mm.
• The surface should not be frozen.
• Working a dried out soil is useless and had better be avoided.
• Work on a terrain that is wet and soggy after heavy rainfall must be postponed.
• The work speed must be adjusted to hardness and type of soil.
• The maximum allowed (forward) slope gradient is 25°.
For your information :
Each roller has propulsion and contains apertures. This has the advantage that
soil cannot stick to it and that irregularities are evened out. Should the rollers
soil too quickly nonetheless, this implies that the terrain is too wet and the work
will consequently have to be postponed.
If the terrain does not meet the above mentioned requirements, preparatory
activities should be carried out first (read § 9.3 Preparation of the work area).
9.3 Preparation of the work area
Laying a lawn efficiently requires preliminary study. For strong grass growth a number of factors
must be taken into account, such as soil structure, presence of sufficient nutrients, correct pH, ...
Preparing the terrain
• As indicated in § 9.2, the terrain must be free from foreign objects. If this is not the case, then
all objects that might otherwise hinder smooth operation must be removed (stones, branches,
rope, steel wire, electrical lines, water hoses, parasol base, pickets, lawn furniture, etc.)
• If certain obstacles cannot be removed, then they should be visibly marked (tree roots, water
drain covers, gas lines, sprinkler systems, power outlets, lawn lighting)..
