4.12 LEVELLING ROLLERS

The levelling rollers are used individually with fi xed harrows,
or in pairs in the case of folding harrows, as shown in the
table below.
Various types of roller can be used, depending on the character-
istics of the soil. However, the function of all the rollers is to level
and pack down the soil while increasing the degree to which this
latter is crumbled on the surface.
These are fi xed to the sides by 2 types of swinging support:
- for rollers up to 2500 in length;
- for rollers from 3000 to 5000 in length.

This can be successfully used in very varied conditions, even when
the soil is fat or damp.
It is advisable to prepare heavy soils in combination with a Seed
drill.

face and at depth.
Dimensions: D = 450; D = 500; D = 600.
Spiropacker Roller
(fi g.74)
Comprises a spiral bar wrapped around a central shaft.
It is particularly suitable for light, sandy soils and leaves a fair
amount of clods on the surface, settling the ground at depth and
forming the most suitable seed bed for the seed drill in certain
situations.
