OPERATION MANUAL VERTICUTTER
EN Verticutting | Blades
7. VERTICUTTING
With a verticutter roll installed, the equipment can be used for removing small stones and
mosses from the lawn as well as for skiving to lines. In order to maintain a healthy lawn in
spring, area around grass roots needs to be aerated. We recommend scarifying the lawn
twice a year, for example in spring and in autumn. In order to achieve good results and to
extend the operating life of the roll with knives, trim the lawn with the help of a mower to a
short height (less than 4 cm) before beginning the work.
Choose the swath depth with regard to the lawn condition and grass height.
Incline the verticutter slightly backward so that the front wheels do not touch ground.
Start-up the verticutter, the roll begins to rotate freely.
Move the equipment across the lawn at a suitable speed, if possible in direct lines.
Always push the verticutter forward at steady speed according to the surface type. A
damage of the lawn can occur if you stopped on one place for a longer time or if you carried
out verticutting on humid or too dry soil.
Be extremely careful when moving backward or when drawing the verticutter so that it cannot
slip out.
Always keep high rotational speed of the cutting blades, thus you can enhance quality of the
treatment significantly.
Do not run over the extension cable while working; make sure the cable is always in a safe
position behind you (Fig. 5). Lead the extension cable in a safe position in the area which has
been treated already.
Never use the verticutter on a too steep terrain. Be particular about your safety on a slope
terrain – danger of slipping and injury. When changing the direction of cutting, always
proceed crosswise, never in the perpendicular direction up or down.
If the collection box was full, empty it so that blades do not get stuck and the engine is not
overloaded.
8. BLADES
(Fig. 6)
Worn-out blades cause low performance and overload of the engine.
Check the condition of the blades before each use. If needed, sharpen the blades or replace
with new ones. Entrust specialists with sharpening and replacement of the blades.
The knives are designed as double-sided. Upturning the knife:
- Unscrew 2 screws (1) from the side of mounting of the bearing (A) on the bottom side of the
cover by the delivered hexagonal wrench.
- Take the aeration roll out from the cover.
- Loosen the hexagonal nut (2) from the opposite side and pull-off the cap (3), flange (4),
knife (5) and spacer rings (6) from the shaft (7) respectively.
- Turn the knife the other way round or use a new one and install everything back again in the
given order.
