3.8.6 PRESSION WHEELS
The coupling of front (1, 2 and 3) and rear (1,2,3 and 4) prerss
wheel Fig. 28 of the equalizer depends on the seeding and soil type:
1) soft rubber wheel, for light, humid and sandy soil;
2) hard rubber wheel, for light, humid and sandy soil;
3) stainless steel fl at type, for light and dry soils;
4) iron grid type, to avoid soil crust compaction.
SOIL SCRAPER WHEELS SEEDING UNIT
Change the position of the spring (B, Fig. 29) to adjust the soil
scraper effi ciency (A, Fig. 29).
Once adjustment is ended, the soil scraper must assure at the
same time the cleanliness of the surface and the rotation of the
wheel itself.
3.8.7 FRONT SOD-BREAKER
The front sod-breaker (Fig. 30) is used to shift likely sods, clots,
residues, etc., from the seeding unit's operating area, thus assuring
seed-planting in the seedbed takes place properly.
Adjust the height of the sod-breaker according to the soil's degree
of preparation.
N.B.: When the interrow distance is less than 20 cm (ORIETTA
«N»), using the sod breaker could cause damage:
ORIETTA «N»
20 cm;
ORIETTA «W»
30 cm;
OLIMPIA (all)
30 cm.
