10. Servicing your mower<br />

Protective gloves must be worn at all times<br />

W during maintenance work.<br />

Checking operating safety<br />

Retighten all screws and nuts after the first few operating<br />

hours and from time to time thereafter. Check<br />

the condition and correct attachment of the cutter<br />

prior to each mowing in order to avoid accidents.<br />

If the cutter is blocked, e.g. by driving over an<br />

obstacle, have a check by your JOHN DEERE dealer<br />

whether parts of the mower are damaged or deformed.<br />

All required repairs should only be done by the<br />

JOHN DEERE dealer.<br />

Replacing and sharpening the blade ) + ≠<br />

Switch off engine and disconnect spark plug<br />

connector, put on safety gloves!<br />

– Turn the mower over onto its left side.<br />

– Insert a screwdriver* into the previously cleaned<br />

blade fastening screw (1) and unscrew whilst<br />

holding the blade.<br />

Remove the blade fastening screw (1), curved<br />

washer (2), washer (3), sliding washer (4), blade<br />

(5) and sliding washer (6) in sequence.<br />

WARNING<br />

The sliding washers may not come into contact<br />

with cleaning agent (e.g. cold cleaner) or oil and<br />

must be replaced from time to time.<br />

– A blunt cutter bar should be sharpened using a<br />

grinder as shown in the sketch since it will otherwise<br />

fall out of balance.<br />

It is recommended that re-sharpening of the<br />

blade be performed by at a specialised service<br />

station. We also recommended that after sharpening<br />

your dealer carry out measurement to check<br />

for imbalance. The blade cutting edges may only<br />

be ground until the value (see the sketch ≠) or<br />

the mark on the blade (ring), has been reached.<br />

– Only use original SABO blades for replacement<br />

purposes. Order no. SA33214<br />

– Blades must be marked permanentoly with name<br />

and /or trademark of the manufacturer or suplier<br />

and with the parts number. Blades may only be<br />

fitted according to the appropriate operating<br />

instructions of the respective mower.<br />

– Reassemble in reverse order, if necessary fit the<br />

curved washer and blower wheel with flange onto<br />

the shaft first. Ensure that the revolving edge of the<br />

sliding washer faces away from the blade bar. The<br />

raised ends of the blade should face the housing.<br />

– Tighten the blade fixing screw with a torque wrench<br />

to 40-45 Nm. Do not use an impact screwdriver.<br />

ATTENTION<br />

Do not leave any tools in the mower!<br />

W Before starting the mower check that<br />

all tools have been removed!<br />

* not supplied<br />

Servicing the wheels<br />

Front wheels<br />

Oil the bearings of the wheels once a year or every<br />

20 operating hours.<br />

– Remove wheel covers.<br />

– Loosen the hexagon head nuts using a socket<br />

spanner and remove the wheels.<br />

– After dribbling oil into the bearings, push on the<br />

wheels and retighten so that they are still able to<br />

rotate easily.<br />

Servicing the rear wheel drive ¡<br />

– Remove the transporter wheels from the wheel<br />

axle after removal of the wheel cover and<br />

loosening of the fixing nut.<br />

– Remove dirt and any grease from the wheel cover,<br />

from the free wheel pinion on the gear shaft and<br />

the drive pinion on the inside of the wheel.<br />

NOTE<br />

Do not remove the free wheel pinion from gear<br />

shaft.<br />

– Grease the pinion pair (free wheel pinion and<br />

drive pinion in the wheel) with a plasticscompatible<br />

multipurpose grease, e.g.<br />

FINA MARSON so that the toothed intermediate<br />

spaces are completely filled.<br />

– When pushing on the transporter wheel make sure<br />

that the pinions engage; it may be necessary to<br />

turn the wheel on the axle slightly.<br />

Servicing the drive “<br />

– It is absolutely essential that the Bowden cable is<br />

easy running for switching on and off, so that the<br />

control drive works perfectly.<br />

– Lubricate the Bowden cable every 10 hours of<br />

operation with thin mineral oil. Slightly bend the<br />

Bowden cable in the region of the point of lubrication<br />

for this purpose.<br />

– The Bowden traction mechanism has been set<br />

ready for operations at the works and requires no<br />

adjustment.<br />

Changing the drive V-belt<br />

– The drive V-belt must be replaced by a<br />

recommended expert workshop.<br />

11. Servicing the engine<br />

The prescribed maintenance and service work must<br />

be performed on a regular basis to ensure long and<br />

fault-free life of the engine.<br />

Keep the engine clean paying particular attention<br />

to the exterior. The perforated plate of the fan wheel<br />

must always be kept free from particles (e.g. grass<br />

cuttings) in particular. Never spray clean with water<br />

as this would result in damage to the ignition system<br />

and carburettor.<br />

Perfect cooling of the engine will only be<br />

guaranteed if the cylinder fins are always kept<br />

clean.<br />

Always lay the mower on the lefthand side for service<br />

work (tank and carburettor facing upwards)<br />

since otherwise there could be starting difficulties.<br />

Oil change <br />

The first oil change of a new engine is necessary after<br />

5 operating hours, and thereafter every 50 hours of<br />

operation or at least once per mowing season.
