Removing/Installing And Adjusting Cutter Deck; Shutting Down The Machine - MTD 900 Series Original Operating Instructions

Operating Instructions
Once a season
Apply multipurpose grease to

the teeth on the steering gear.
Lubricate the steering linkage

with a few drops of light oil.
Lubricate all moving parts and

bearing surfaces with a few
drops of oil (control levers,
cutting height adjustment).
Clean the spark plug and check

the gap between the electrodes
or replace the plug. See engine
handbook.
The rear axles must be lubricated

with a special-purpose (water-
repellent) grease at a specialised
garage.
Have the cutting blade

sharpened or replaced
in a specialist workshop.
Note
Regularly check (when visiting your
workshop) the condition of the
mower deck V-belt. This is parti-
cularly important for positively
controlled mower decks.
Removing/Installing and
adjusting cutter deck
Danger
Risk of injury through the engine
being unintentionally started.
Protect yourself from injury. Before
doing any work to this appliance:
– park the appliance on a level
surface,
– turn the engine off,
– remove the ignition key,
– switch off PTO,
– lock the parking brake.
– wait until all moving parts have
come to rest and the engine has
fully cooled.
– remove the spark plug connector
on the engine in order to prevent
the engine from accidentally
being started.
Danger
Risk of injury from sharp cutting
blade.
Wear protective gloves.
Disassembly
Install the cutter wheels at the

highest position.
Lower the cutters.

Remove the V belt from the PTO

clutch (motor pulley). Depending
on the model, remove the V-belt
guide bracket (Fig. 23)
beforehand. Ensure that the
location holes are used again
for subsequent installation.
Withdraw the pin (1, Fig. 15) to

disconnect the cutters from the
suspension.
Repeat these steps on the left

side of the appliance.
NOTE – In doing so, support the
cutters firmly so that they cannot
simply drop to the ground.
Move the cutting height setting

lever into the top catch.
Remove fixing bracket from the

cutter deck (Fig. 22). Pull cotter
pin (A) and pull the fixing bracket
(B) out of the holder.
Pull out the cutters (to the right)

from beneath the appliance.
Assembly
To reinstall the cutters perform
the above steps (for removing
the cutters) in reverse order.
Work proceeds faster when you
are assisted by a second person.
Make sure that the suspension
units are in their respective
recesses on the cutter mount and
the pin has engaged correctly.
Setting the cutter level
When mowing does not appear to
be parallel to the lawn the cutters
can be aligned.
Note
Before aligning the cutters check
the tyre pressure on the appliance.
Setting the side level
Fig. 13
Raise the cutters to the top.

Carefully turn the outer cutters

(risk of injury) transverse to the
drive direction.
Measure the distance between

the ground and the ends of the
two outer cutters. The result
should be identical. To obtain
the correct level you may have to
turn the adjusting segment (2) on
the right cutter side. To do so first
loosen (but do not remove) the
cap bolt (1) and retighten this
after the adjustment.
Set the level from front to back
Fig. 12
Note
Set/check the side level before this
adjustment.
Raise the cutters to the top.

Carefully turn the outer cutters

(risk of injury) parallel to the drive
direction.
Measure the distance between

the ground and the end of the
right cutter. The end of the front
cutter should be about 3.2–6 mm
lower than the end of the rear
cutter. You may have to adjust
the front receiver. To do so,
loosen the locknut (1) and turn
the setting nuts (2) steadily to
obtain the correct level. After
setting, retighten the locknuts (1).
Shutting down
the machine
Warning
Damage to mower materials
Store the mower with engine
cooled down only in clean, dry
areas. Always protect the mower
against rust if it is to be left for

over the winter.
At the end of the grass-cutting
season or if the mower is not going
to be used for longer than one
month:
Clean the mower and the grass

catcher.
Protect all metal parts against

rust by wiping them using an
oiled cloth or spray with spray oil.
Recharge the battery using

a battery charger.
