Innovative overseeding technology DZC450

Since the new grass seed is inserted between existing vegetation when overseeding, it is essential for the success of the treatment that the seed can
germinate as soon as possible and that growth opportunities are maximised. The patented operating principle of the DZC450 ensures ideal conditions
for the introduction of seed:
1. Cutting open the soil
The cutting blades at the front of the machine cut open 8 mm (0.31") deep grooves in the
soil of the lawn in preparation for the grass seed.
2. Removal of excess soil
The blades rotate over the top and cast the soil in an arch to the rear of the machine so that it
does not fall into the newly cut grooves.
3. Precision sowing
A clever and compact seed distribution system, Helix Seed DuctTM, carries the seed under the projected
excess soil into small funnels leading to discharge channels precisely located above the clean grooves.
4. Injection
A small air pressure generator blows air through the seed funnels so the seed is blown while it is being
distributed. This helps the seed to settle faster and with more precision in the grooves.
5. Rollers
The powered rubber roller immediately follows the seed distribution process and ensures that
there is good contact between the soil and the seeds by pressing the earth down.
6. covering the seed
The flow of projected excess earth falls just behind the roller on the sown area. The earth covers
the seedbed and provides a protective layer for the seed, increasing the chances of germination and
