OPERATING INSTRUCTIONS
ROTARY RAKER
Ref: RR3

DESCRIPTION
By teasing out the thatch and moss from your lawn you will make it more
resistant to drought, insects and disease problems. By removing this layer of
thatch the grassed area will regenerate naturally and will become more receptive
to fertilisers and other pests and disease control products.
The SCH Rotary Raker’s powerful 5.5Hp Honda petrol engine with twin 'v' belt
drive rotates four rows of free floating scarifying blades, which carry out the vital
dethatching process.
For areas that are inaccessible to the garden tractor the unit can be manually
operated with easy attachable handle which is provided with the machine.

SAFETY INSTRUCTIONS
Do not place any part of your body under the canopy whilst the engine is
running.
All guards must be in position when the engine is running.
No adjustments or maintenance may be carried out with the engine
running.
Parts of the engine will be extremely hot –beware where you place your
hands.
The engine noise level is given on the unit. Ear protectors are advised.
When the operating lever is in the ‘stop’ position the rotor will continue
to revolve until the engine is switched ‘off’.
Due to the dual use mode of the unit there is no provision for a ‘dead mans’
handle stop. This means the engine will run when you alight from the tractor seat
or release your hand grip on the manual handle.
No other persons other than the tractor driver/ operator should be in the
work zone.
If you are not mechanically minded we advise you to obtain the services
of a person to talk you through the safe operation of the unit.
The safety instructions must be read before operating the unit.

TO START THE UNIT
1. Refer to starting instructions as printed in the engine manual.
2. The operating lever must be in the starting position.
3. Make sure the throttle switch is in the ‘ON’ position.
4. In the towing mode, the unit must be securely attached to the unit. In the
pedestrian mode make sure the unit is ‘choked,’
TO STOP THE ENGINE
Place the throttle lever in the ‘stop’ position; switch off the engine as directed in
the engine manual
OPERATION
From the seat of the tractor increase the speed of the rake by moving the throttle
lever.
Operation forward speed –a medium to fast walking pace.
The correct operation of the unit is when the tines tease the surface of the
grassed area. The tines should not penetrate the soil. Failure to adjust the
height correctly will result in premature replacement of blades, render the drive
belts unserviceable and cause damage to grassed areas.
The height can be adjusted by the jack leg on the front of the machine.

INITIAL HEIGHT ADJUSTMENT
Ensure that the engine is switched off.
Initial adjustment is carried out on the front adjuster screw.
By turning the jack leg clockwise, the blades will raise. By turning the
jack leg anti-clockwise, the blades will lower.
HEIGHT ADJUSTMENT
When the correct adjustment cannot be obtained from the front screw adjuster,
slacken the four bolts holding the rear wheels to the unit. The stub axle can then
be moved upwards. Ensure that each axle is raised the same amount and re
tighten the four bolts.
Fine adjustment must be made on the front height adjuster (see initial height
adjustment).
The machine should be operated as level as possible.
MAINTENANCE
Engine as per engine manual attached
Keep the front adjuster screw well oiled.
Occasionally lubricate the wheels with light oil.
Periodically check that all nuts and bolts are tight.

WALK BEHIND SETUP
Ensure the RR3 is turned off prior to conversion.
To convert the RR3 to walk behind:
Remove the front towing hitch.
Insert the two manual handle ends into the corresponding points on the
rear of the unit.
Place the D pin through the two holes on the rear of the unit and secure
in place.
The throttle lever will be in easy reach.
As the rotor blades rotate, they will help pull the machine forward - alleviating
some of the effort required to manoeuvre the machine.
