If top dressing should be applied, apply this first
before
using the Verti-Drain ® 2519.
If the soil is hard to aerate, sprinkle water on the soil. Afterwards, use thinner and shorter pins or
adjust the working depth. If this is not done, the machine will ultimately suffer damage.
Hollow pins
The soil can be mingled with hollow pins. Various sizes are available (see the Parts page). The
opening of the pin should be in the direction of the rear of the machine.
In case of using hollow pins, it is important that the pin angle is set to 90°. The heave movement of the
pin in the soil is minimal and this way you make a nice ‘clean’ hole. The pin can ultimately break if the
pin always moves in the soil under an angle smaller than 90°.
If a lot of dirt is created during pricking with hollow pins, reduce the revolutions or sprinkle water. Dirt
can accelerate the wear & tear of the machine.
If the lawn becomes damaged, use solid pins first in order to create a set of healthy roots or adjust the
working depth.
If the pins jam, then the soil is very compressed. First, you should use solid pins to break the soil
open. Or sprinkle water or adjust the working depth.
