7.2. Adjustment of Working Depth
The working depth of the cultivating knives is determined in relation to the position of the rear roller.
Adjustments of the roller position are made by turning the cranks (1), Fig.9-2, located on both sides of
the harrow. Remember that the number of revolutions of the right and left crank was the same, which
ensures an even working depth on both sides of the harrow. The more screwed in the screw, the greater
the working depth.
Check the working depth by pushing the rigid strip into the cultivated soil until you feel resistance.
The depth of the strip insertion in the cultivated soil is the working depth.
7.3.
Adjustment of Fender Beam
The adjustment is made by raising or lowering the beam and securing it in a given position by means
of bolts (1), Fig.9-3, secured with linchpins (on both holders equally). The beam located directly behind
the rotors serves for additional crumbling of clods on the soil surface. The lower the beam is set, the
greater the crumbling. The beam cannot work like a drag, i.e. scrape the layers of loosened soil.
7.4.
Adjustment of Side Shields
The shields (RH and LH) are pivoted so that the stones can leave the work area quickly. Set the shields
by loosening the screws (1), Fig. 9-4, and shifting the shields into a suitable notch so that they do not
sink deeper than 2 cm into the soil. A deeper setting can damage the shields.
7.5.
Adjustment of Scrapers
In order to properly clean the pipe of the tyre and toothed rollers from the soil sticking to them, the
size of the gap between the pipe and the scraper should be as small as possible. The scraper settings
are made by loosening the nut on the scraper fastening screw, then setting the scraper in the
recommended position and tightening the nut. After setting all the scrapers, ensure that the scrapers
do not rub against the pipe during rotation of the roller. After one side of the scraper become worn,
turn it to the other side.
7.6.
Setting Supports Under the Seed Drill Wheels
Before starting work with HERMES + seeder unit and after each working depth change, set the
angle/bolts (1) (if any), Fig. 6-9, and the height of the supports/bolts (2), Fig.9-7, so that there was no
interference between the seeder and the rotary harrow after placing the seeder on the supports.
7.7.
Changing the Speed of Working Knives
In order to increase the intensity of soil crumbling, it is necessary to increase speed of the rotors with
working knives by replacing the gears in the gear (see Fig. 9-5).
The speed of the PTO must be 540 RPM or 1000 RPM (Hermes 4.0 option). Such parameters ensure
the proper operation of the machine.

Caution!
After replacing the wheels (up-down or down-up), the mating wheels must touch the same tooth
working surfaces as before the replacement!
