Make sure the lawn is clear of sticks, stones, bones, wire and debris. They could be thrown by the blade

Stop the engine and disconnect the spark plug wire before clearing blockages, checking, or working on the mower.

Before using, always visually inspect to see that blades, blade bolts and cutter assembly are not worn or damaged. Replace worn or damaged blades in sets to preserve balance.


Check all nuts, bolts and screws often; always be sure the mower is in a safe operating condition. Use only genuine replacement parts.

Refuel outdoors only. Do not smoke while fuelling engine. Add fuel before starting the engine. Never remove the cap off the fuel tank or add fuel while the engine is running or the engine is hot. If fuel is spilled, do not attempt to start the engine but move the machine away from the area of the spill and avoid creating any source of ignition until fuel vapours have dissipated.

Do not mow whilst people, especially children or pets are in the mowing area.

Replace worn or faulty silencers (muffler)

Mow only in good daylight.

Never use the mower unless the grass catcher or guards (rear flap) provided by the manufacturer are in position.

Start the engine carefully with feet well away from the blade.

Do not operate the engine in a confined space where exhaust fumes (carbon monoxide) can collect.

Stop the engine whenever you leave the mower, even for a moment.

Do not allow children or people unfamiliar with these instructions to use the mower.

Store the mower in a well-ventilatedroom away from naked flames such as may be found in hot water heaters.

Do not over-speedthe engine or alter governor settings. Excessive speed is dangerous and shortens the mower life.

It is advisable to wear suitable eye protection when operating a mower.

Turn the fuel off at the conclusion of mowing and reduce the throttle setting during engine run-out.

Store fuel in a cool place in a container specifically designed for the purpose. In general, plastic containers are unsuitable.

Stop the engine, disconnect the spark plug wire and inspect the mower if :

a)the mower begins to vibrate abnormally; or

b)after striking a foreign object.

Before carrying out any maintenance on the mower remove the spark plug lead from the spark plug to prevent accidental starting.

Engine air cleaner

Refer to the engine owner’s manual for detailed maintenance instructions.

The engine air cleaner elements must be serviced after every 25 hours of normal mowing. The elements must be serviced more regularly if the mower is used in dusty conditions. Replace immediately if the element is damaged.

Spark plug

Refer to the engine owner’s manual for detailed maintenance instructions.

For best results, remove the spark plug every 50 hours for gap checking and replace every 100 hours of use. Replace the spark plug at any time if it is found that the electrodes are pitted or burned or the porcelain cracked. For replacement refer to engine owner’s manual for correct spark plug.


Check the condition of the muffler periodically for rust and cracks. Replace if found to be damaged as this can lead to increased exhaust noise. Replace only with a genuine original equipment part.

Blades - refer figure 9.

Check the condition of the blades and central fasteners at regular intervals, or after striking a solid object, or if the mower begins to vibrate abnormally. The blades with use, will lose their sharp edge and the quality of the grass finish will deteriorate. When this happens, all the blades should be removed and replaced with a new set of blades. Always use genuine Rover replacement blades and only replace blades in sets to maintain balance.


Always ensure the engine is stopped and the spark plug lead is removed before attempting any maintenance on the mower.

Secure the mower safely when tilted upwards to access the underside.

To ensure safe operation and long life it is recommended to clean the mower after every use. This will prevent corrosion, overheating and fire risk while ensuring ultimate performance.

Washport (where fitted)

Place the mower outdoors on a flat surface.Set the height to maximum.

With the engine stopped connect a garden hose with a snap on connection, to the washport fitted to the inside face of the cutting chamber. Refer figure 11.

Turn the garden hose on.

Return to the mower and start the engine and run at full speed for 1 minute.

Stop the engine and turn off the garden hose.

Remove the garden hose from the washport.

Figure 11. Washport Connection

Inspect the underside of the mower, if not completely clean use garden hose to flush out remaining debris.


Cleaning the Underside of the Mower


Always ensure the engine is stopped and the spark plug lead is removed before attempting any maintenance on the mower.

Place the mower outdoors on a flat surface.

Set the cut height to maximum.

With the engine stopped, remove the grass catcher or mulch plug and lift open the discharge flap.

Use a garden hose to wash out all the grass clippings.

Inspect the underside and repeat the cycle if still not clean.

Cleaning the Upper side of the Mower


Do not hose the engine as water can damage the air cleaner and ignition system.

Use a dry cloth or soft brush to remove all loose clippings.

Use a damp cloth with mild detergent to clean away oil or other grime.

Wash the grass catcher and/or mulch plug separately from the mower with a hose. Wash all clippings out of the inside, outside and from the grass catcher mesh.

Let the mower dry before storing.

MAINTENANCE - Mulch mowers (only)

Mulching Equipment

For optimum mulching performance

The mulch blades are to be kept sharp.

Maintain the blade sharpening angle when sharpening.

Keep the cutting edge feather free when sharpening.

Keep the underside of the mower deck and the mulch plug free of build-up.

Refer to the “Cleaning” section on page 7 and 8.


Some mowers are fitted with an option for mulch mowing.

A mulch plug is supplied with these mowers and it is installed in the rear discharge chute (as noted in the “OPERATION” section of this manual) to perform mulch mowing.

The following information provides advice on mulch mowing.


The mulch mowing setup reduces the grass clippings into very fine particles.

The design allows for the even distribution of the grass particles at the base of the lawn. The mulched clippings can then:

Break down quickly, releasing nutrients into the soil, saving on fertilizer costs.

Reduce evaporation of moisture from the soil which reduces watering costs and effort.

Help to control temperature extremes protecting the roots of the grass.

Assist in controlling soil erosion.


Figure 12. Grass height



Research has shown that lawns are usually cut too short,

Grass, like any other plant life, relies on photosynthesis to regenerate and survive. Reduced leaf size (from cutting too low) can seriously effect a lawn by:

Making it easy prey for disease.

Encouraging weeds to take hold.

Exposing the soil to:

-greater evaporation

-temperature extremes; and


Raising the cut height and using mulch mowing follows the best practice for nurturing a healthier more attractive lawn with less water usage.


Because you mulch as you mow the time and cost savings are also significant:

Eliminating raking of leaves before mowing (Mulch mowing picks up and converts fallen leaves into mulch).

Eliminating raking of cut grass

Saves time spent emptying the catcher.

Automatically disposing of grass clippings.

Eliminating the need to dispose of clippings at the refuse tip.


Mulch mowing is an art form and to produce the best results consistently, follow these useful hints:

Do not attempt to mulch if the grass is too wet.

Wet grass tends to clump together and does not evenly spread out. It also clogs up the underside of the base.

Do not mulch mow on too low a cutting height.

Remember the maximum cut should be 25mm off the top of the grass, or 1/3rd the grass (blade) height, whichever is the lesser amount . Refer to figure 12.

Do not push the mower too fast.

To obtain the best finish it may be necessary to regulate the ground speed.

Run the engine at full throttle.

Running the engine at low speed does not allow the blades to mulch the grass efficiently.

Keep the mulch blades sharp.

The mulch blades are designed to cut and recut the blades of grass.

If the mulch blades are not kept sharp,

mulching performance will be reduced.

Keep the underside of the mower and

mulch plug clean.

Build-upof grass under the mower base blocks the airflow created by the mulch blade and reduces the mulching performance.

If the conditions for mulch mowing are not ideal and some clipping trails are visible after cutting it may be necessary to:

1.Fit the grass catcher and catch mow.

2.Re-mowover the visible clippings

3.Raise the cut height.

4.Rake the clippings up after mowing.
