9.5 Adjusting the Bowden cable for the
mower mechanism (29)
WARNING!
Risk of injury!
Any work on the mower mechanism
must only be carried out when the en-
gine is switched off!
If the mower mechanism can no longer be
switched on or off again, the switching mecha-
nism on the Bowden cable can be adjusted.
NOTE
If the mower mechanism cannot be
switched on or off at all, have your ride-
on mower checked and repaired by your
customer service workshop.
■
To adjust the Bowden cable (29/1), loosen
the two nuts (29/2) and (29/3).
■
If the mower mechanism can no longer be
switched on correctly, loosen the nut (29/3)
and adjust the Bowden cable (29/1) with the
nut (29/2) until the mower mechanism can be
switched on correctly again.
■
If the mower mechanism can no longer be
switched off correctly, loosen the nut (29/2)
and adjust the Bowden cable (29/1) with the
nut (29/3) until the mower mechanism can be
switched off correctly again.
9.6 Adjusting the mower mechanism (30)
The cutting height setting can be adjusted if it is
no longer correct as a result of wear or because
you have changed the tyres.
1. Park the ride-on lawnmower on a straight and
level surface.
2. Set the cutting height adjustment (09/2) to
the lowest position.
3. Release the locking pin (30/2) from the hold-
ing pin (30/3).
4. Pull the holding pin (30/3) out of the mower
mechanism and the adjusting pin (30/1).
5. Adjust the cutting height accordingly with the
adjusting pin (30/1).
6. Push the holding pin (30/3) back through the
adjusting pin (30/1) and the mower mecha-
nism, and secure the holding pin again using
the locking pin (30/2).
The correct setting of the mower mechanism –
25 mm at the front and 35 mm at the rear – is
measured at the lowest cutting height setting.
These dimensions refer to the lower edge of the
mower mechanism to the ground.
