grass catcher box and correctly installed
handlebar.
1 0.2 Motorstop lever
The models MB 650 T, MB 650 V,
MB 655 V are equipped with a
motorstop device.
The engine stops when motorstop
lever (1) is released during running
operation.
The engine and blade come to a standstill
within 3 seconds.
Measuring the run-on time
Following engine start-up, the blade
rotates and a wind noise is audible. The
run-on time corresponds to the duration of
the wind noise after the engine stops. This
can be measured using a stopwatch.
The models MB 650 VS,
MB 655 VS, MB 655 YS are
equipped with a
Blade - Brake - Clutch ( BBC ).
Two-hand operation:
The mowing blade can only be engaged as
follows with the engine running:
● Press blade stop lever (1) with one
hand and, while keeping it pressed, pull
blade clutch lever (5) upwards with the
other hand and allow it to engage.

Integrated blade run - down brake:
When the blade stop lever is released (or
after releasing the handlebar), the mowing
blade is disengaged and braked to a
standstill within a maximum of 3 seconds,
while the engine continues to run. (

A perfect, thick lawn is achieved by
– Mowing at low driving speeds.
– Mowing regularly and keeping the grass
short.
– Not cutting the lawn too short in hot, dry
conditions as it will be burnt by the sun
and become unsightly.
– Using a sharp mowing blade – mowing
blade should therefore be sharpened
regularly (specialist dealer).
– Changing the cutting direction regularly.
1 2. 1 Working area for operator
● For safety reasons, the operator
must stay within the working area
behind the handlebar when starting the
engine and when the engine is running.
Always observe the safety distance
provided by the handlebar.
● The lawn mower must only be operated
by one person. Other persons must
keep out of the danger area. (

1 2.2 Applications
The lawn mower is equipped with a multi-
blade and can be used as a
mulching
mower or rear discharge mower as well
as a grass collector .
● To use the machine as a mulching
mower, install the mulch insert. (

● For use as a rear discharge mower or
grass collector (with grass catcher box),
remove the mulch insert from the
machine. (

1 2.3 How should mulching be
performed?
A cutting height between 4 and 7 should
be selected for mulching, as this is the
most suitable height for shredding the
grass.
If the cutting height is too low, the mower
housing may become clogged, resulting in
blockage of the mowing blade
It is important to select the correct
operating speed and cutting height for
mulching to allow the mowing blade to
achieve optimal grass shredding and a
good cutting pattern.
In high grass, it is advisable to work in
several stages and in the higher cutting
height settings.
Mulching should not be performed when
the grass is too high or wet.
Risk of injury!
If the run-on time of the blade
exceeds this delay, stop using the
machine and take it to your
specialist dealer.
11 . Blade brake clutch (BBC)
Risk of injury!
Operation of the blade-brake-clutch
must be checked before each use.

the handlebar.
