Mulching: composting and spreading.
Rear ejection: ejects the grass in a line behind
the deck.
The deck is set for mulching on delivery. In order
to eject the grass in a line behind the deck, the plug
in fig. 6 must be removed.
Set the deck in service position (see 5.3) in order to
remove/install the plug.
4 USING THE MACHINE
Check that the grass that is to be cut is
completely free of foreign objects such
as stones etc.
5 MAINTENANCE
5.1 Preparation
All service and all maintenance must be carried out
on a stationary machine with the engine switched
off.
4.1 Cutting height
The best cutting results are achieved when the
when the top third of the grass is cut off. I.e. 2/3 of
the length of the grass remains. See fig. 18.
Prevent the machine from rolling by al-
ways applying the parking brake.
If the grass is long and has to be cut significantly,
cut twice using different cutting heights.
Do not use the lowest cutting heights if the lawn
surface is uneven. This would entail a risk of the
blades being damaged against the surface and the
lawn’s top layer of soil being removed.
Stop the engine.
Prevent unintentional starting of the
engine by disconnecting the spark plug
cable from the spark plug and remov-
ing the ignition key.
4.2 Incline
The cutting deck’s rear section can be lifted so that
the deck has a greater forward incline than that
provided by the basic setting. This incline affects
the cutting results as follows.
5.2 Washing position
1. Activate the parking brake.
4.2.1 No incline
2. Set the implement lifter in transport position.
3. Set the lowest cutting height.
4. 125 Combi Pro, 107 M HD, 121 M:
Disconnect the rear section of the cutting deck
by removing pins and any washers. See fig. 2,
7:I and 13.
107 M: Lift up the rear section of the cutting
deck, undo the catches (12:L) and lower.
5. Grip the front edge of the deck and lift up. Hook
on the chain so that the deck is pointing diago-
nally upwards. See fig. 19.
It is absolutely forbidden to start the engine
when the deck is in the washing position.
Reset 125 Combi Pro in accordance with 3.1.1,
point 8.
When the deck is in the basic setting, the best
mulching effect and good dispersion of the cut
grass are achieved. The basic setting is recom-
mended for normal grass.
4.2.2 Incline
When the cutting deck is inclined forwards, the
mulching effect is reduced while the cut grass is
dispersed better.
Inclining forwards is recommended for thicker
grass.
4.3 Mowing advice
In order to achieve optimum mowing results, fol-
low the advice below:
Reset 107 M HD in accordance with 3.2.1, point 7.
Reset 121 M in accordance with 3.2.1, point 7.
Reset 107 M in accordance with 3.3.1, point 7.

5.3 Service position
5.6 Replacing blades
1. Activate the parking brake.
Wear protective gloves when changing
blade(s) to avoid cutting yourself.
2. Set the implement lifter in transport position.
3. If the deck has electrical cutting height adjust-
ment, disconnect the cable from the machine.
See fig. 15.
4. 125 Combi Pro, 107 M HD, 107 M:
Set the highest cutting height.
121 M: Set the cutting height in the centre posi-
tion.
Check that the blades are always sharp.
This produces the best cutting results.
Always check the blade(s) after a collision. If the
blade system has been damaged, defective parts
should be replaced.
Always use genuine spare parts. Non-
genuine spare parts can entail a risk of
injury, even if they fit the machine.
5. 125 Combi Pro:
Remove pins and washers. See fig. 2.
107 M HD:
The deck is equipped with blades accord-
ing to the following alternatives:
Remove pins and washers. See fig. 13.
107 M: Lift up the rear section of the cutting
deck, undo the catches (12:L) and lower.
121 M: Disconnect the rear section of the cut-
ting deck by removing the pins (7:I).
•
Separate blades, screwed into place on the blade
bars. See fig. 22.
•
Full blade. See fig. 23.
5.6.1 Separate blades
6. Remove the belt cover. See fig. 5:E, 8 and 10.
The number in the figure indicates the key
width.
The blades are replaceable. When replacing, both
blades on the same blade bar must be replaced to
avoid imbalance.
Tightening torque:
Screws (22:P) - 24 Nm
Shear bolts (22:Q) - 9.8 Nm
In the event of a collision, the shear bolts (22:Q)
can break and the blades bend back. If this has hap-
pened, install genuine shear bolts and tighten as
above.
7. Only 125 Combi Pro:
Remove the belt guide (5:F).
8. Grip the belt tensioner’s lever with your left
hand. Pull the lever and unhook the tensioner
from the belt with your right hand. See fig. 16.
9. Force the belt off the deck’s pulley.
10.Grip the front edge of the deck and lift up. Lift
until the deck is completely vertical and rest the
rear edge on the floor. See fig. 20.
5.6.2 Full blade, fig. 23
Reset 125 Combi Pro in accordance with 3.1.
Reset 107 M HD in accordance with 3.2.
Reset 107 M in accordance with 3.3.
Reset 121 M in accordance with 3.2.
The full blade is replaced when the edges are worn.
Install the new blade with the punched text facing
down.
Tightening torque: 24 Nm.
5.4 Cleaning
5.7 Synchronising, blades
The underside of the deck must be cleaned after
each use.
The following decks have synchronised blades:
•
•
•
107 M
107 M HD
121 M
Set the deck in washing position.
Clean the underside of the deck carefully. Use a
high-pressure washer, scraper and/or brush.
When the surfaces are completely dry and clean,
touch up the paintwork. Use durable yellow paint
intended for metal outdoors.
If one of the blades has struck a solid object (e.g. a
stone), the positive drive belt may mesh incorrect-
ly, endangering the synchronisation. This entails a
risk of the blades colliding with each other.
Correctly synchronised blades must be offset 90°
from each other. See fig. 24.
Always check synchronisation after a collision.
If there is any suspicion of incorrect synchronisa-
tion, contact an authorised Stiga workshop for re-
pair work to be carried out.
The blades in the 125 Combi Pro are freely rotat-
ing.
5.5 Wheels
125 Combi Pro is fitted with two lubricating cups
(21:M) for the vertical shafts.
107 M HD is fitted with two lubricating cups for
the vertical shafts (21:M) and two lubricating cups
(21:N) for the wheel axles.
The grease nipples must be lubricated with univer-
sal grease after 50 hours of operation.
