5.5 Landscaping machine operation
Pre-rolling:
Pre-rolling breaks up larger clods of earth so that seeds will not be buried too deeply nor be covered by
excessive soil.
Sowing:
The sowing mechanism features a shaft of wear-resistant Perlon brushes which prove to be very
effective against small foreign objects and tend not to jam as is the case with more rigid equipment.
Precise seed allocation is provided on a large scale.
The seeds held within the seed bin are ejected from the brush shaft through an adjustable perforated
plate once the locking cap has been opened, thereby falling through the seed deflector (simultaneously
a windscreen plate).
Raking the seed into the soil:
Our patented power-driven seed dibbler with cleaning cage also works in pebbly, clumpy or damp soil
without fail.
Behind the seed discharge, the dibbler lodges the seeds into the soil. The dibbler is driven in such a
way that each individual spike will make a raking movement approximately 3 cm long (roll delay).
This works more seed into the ground than if the dibbler were simply to roll along atop the soil.
Finish-rolling:
Finish-rolling compresses the surface of the soil and the seed evenly, allowing the seed to germinate
faster. Advantages of finish-rolling include how it allows for easy steering and turning of the machine
without displacing soil and how it cannot become clogged by stones or clumps of earth. Detrimental
soil compaction is a thing of the past with the light weight of the SEMBDNER RS.
Operating the landscaping machine:
The angled control lever for the seed discharge is located within reach of the operator station.
Open = vertical / Closed = to the right.
To seed, open the control lever for the seed discharge and immediately bring the gearshift lever into
forward drive; the dead man’s handle on the handlebar must now be pulled to avoid the engine
switching off.
When turning or going in reverse, close the seed discharge.
If seeding is paused within an area to be sown, run the machine approximately 15 cm backward before
continuing work so that there will be no unseeded strips.
Care must be taken that sowing follows in a precise lane-to-lane orientation to avoid both double-
sowing of lanes as well as omitting any spots.
In order to preclude any such errors when using very high-grade lawn seeding, sowing can also
transpire crosswise with half the amount of seed. This function largely compensates for any seeding
errors due to imprecise driving.
When turning the machine or running in reverse in tight spaces
! or near stationary objects: Always ensure you maintain a safe distance!
Turning the machine is a function of just the large pressure roller when you press downward on the
handlebar; reduce driving speed at the same time with the throttle.
Adjusting the dibbler: the infeed depth of the dibbler can be adjusted and/or switched off completely
by means of the control handle on the left side of the machine, doing so allows the machine to be used
as just a roller.
When sowing, dibbler infeed depth should be no greater than 2 cm. If necessary, the control lever can
be lifted out of the fixed aligning bore, resulting in a “floating” dibbler (in free suspension).
Disengage the dibbler when not in actual use to prevent the dibbler spikes from becoming damaged.
