b. Setting the work depth
To maximize the growing chances of the sown grass seeds, they should be covered by a thin
layer of soil. In principle, this equates to a sowing depth of +/- 3 to 5 mm (0.1" to 0.2"). To do
this, the cutting depth of the machine should be set to a slightly deeper level. A work depth
of 8 to 10 mm (0.3” to 0.4”) is recommended. This means that the blades will penetrate the
soil up to this depth, and the grooves will have this size on average.
The depth setting is fitted centrally at the front of the machine: there is an adjustment disc
there with a diagram with reference indications.
When the
new blades
are used for the first time, the depth setting is "4" (see red marking
line), which corresponds to a work depth of 10 mm (0.4").
Please note:
The purpose of the depth setting is not to make the blades work
deeper, but to compensate for the loss of work depth due to wear and tear!
Please bear in mind that the blades will shorten due to normal wear, and that this will inter-
fere with the depth setting. The depth setting is intended to correct the work depth under
the influence of this wear and tear. The indication on the diagram is not a representation of
the depth, but only a frame of reference for this setting. By shifting the adjustment disc by
one notch, the work depth will be adjusted by
±
2.5 mm (0.1").
Setting procedure:
• Place the machine on a part of the lawn where the ground is level.
• Check that the machine is in transport mode.
• Start the machine's engine (read § 9.5; page 47)
• Start the blades by squeezing the red blade handle.
• Press the handlebars down for a moment so that the front wheels lift.
• Squeeze the depth lever and move the handlebars back up in a controlled manner to lower
the machine to its operation mode.
• Then pull the machine backwards about 50 cm (20") with the blades switched on and in
operation mode.
• Then push the handlebars down again to put the machine in transport mode and switch off
the blades and the engine.
• At the front of the machine, the routed grooves are now clearly visible.
