Frequently Asked Questions - Rancher 27155 Rover

How do I start the Rover Rancher 27155 lawn mower?

To start, ensure the fuel shutoff valve is open (if equipped), push the primer bulb 3 times, set the throttle to fast/choke position, grasp the starter handle and pull slowly until resistance is felt, then pull briskly. Once the engine starts, gradually move the throttle to run position.

What type of oil should I use for the Rancher 27155?

Use a high-quality detergent oil classified as SF, SG, SH, SJ or higher. For temperatures above 40°F (4°C), use SAE 30. For all temperatures, use SAE 10W-30. Do not use synthetic oil.

How do I adjust the cutting height on this mower?

The cutting height is adjusted by moving the cutting height levers on each wheel. Pull the lever outward, slide it to the desired position (1=lowest, 6=highest), then release to lock. Ensure all wheels are set to the same position.

How often should I change the engine oil?

Change the oil after the first 5 hours of use, then every 50 hours or every season. Always change oil while the engine is warm to ensure complete drainage.

How do I clean the mower deck?

After each use, tilt the mower with the air filter side up and scrape off any grass clippings from the underside of the deck. Use a hose to rinse if desired, but avoid direct water into the engine or air intake.

What should I do if the mower vibrates excessively?

Excessive vibration may be caused by a bent blade, loose blade, or debris caught in the blade. Inspect the blade for damage and tighten it to 45-50 ft-lbs. Remove any wrapped debris. If vibration persists, check the engine mounting bolts.

How do I replace the blade on the Rancher 27155?

Disconnect the spark plug wire, tip the mower on its side (air filter up), use a block of wood to hold the blade, and remove the blade bolt with a wrench. Install the new blade with sharp edge towards the ground, tightening the bolt to 45-50 ft-lbs.

Is the Rancher 27155 self-propelled?

Yes, the Rancher 27155 features a rear-wheel drive self-propel system. Squeeze the drive bail to engage. The speed is fixed; adjust by pulling or releasing the bail as needed.

How do I store the mower for winter?

Run the engine dry of fuel, change the oil, remove the spark plug and add a teaspoon of oil into the cylinder, pull the starter slowly to distribute, then replace the spark plug. Store in a dry, clean place.

Where can I find replacement parts for the Rover Rancher 27155?

Replacement parts such as air filters, spark plugs, blades, and belts are available at most outdoor power equipment dealers. Use the model number 27155 when ordering. Online retailers and the Rover website also stock parts.

SAFETY INSTRUCTIONS

This product is manufactured to comply with Australian Safety Standards. If non-genuine replacement parts; including blades; are fitted to this product it may no longer meet that Australian Safety Standard and Rover Mowers Warranty. The fitting of non-genuine replacement parts could result in a serious injury, and, or machine malfunctioning which may result in litigation against the person or persons responsible for the alterations.

* Know your controls. Read the owner's manual carefully. Learn how to stop the engine quickly in any emergency.
* Do not allow children or people unfamiliar with these instructions to use the mower. Do not carry passengers.
* Make sure the lawn is clear of sticks, stones, bones, wire and debris. They could be thrown by the blade.
* Do not mow whilst people, especially children, or pets are in the mowing area.
* Never mow across the face of the slope, unless the mower is designed for this purpose.
* Exercise extreme caution when on slopes. Reduce speed on slopes and in sharp turns to prevent overturning or loss of control.

Do not stop or start suddenly when going uphill or downhill.

* Stay alert for holes in the terrain and other hidden hazards.

Use care when pulling loads or using heavy equipment

(a) use only approved drawbar hitch points
(b) limit loads to those you can safely control
(c) do not turn sharply
(d) use care when backing up, and
(e) use counterweight(s) or wheel weights when suggested in the owner's manual.

* Watch out for traffic when crossing or operating the mower near roadways.
* Stop the blades rotating before crossing surfaces other than grass.
* When using any attachments, never direct discharge of material toward bystanders nor allow anyone near the machine while it is in operation.
* Before leaving the operator's position -

(a) disengage all clutches and secure cutting units
(b) change into neutral and set the parking brake, and
(c) stop the engine and remove the key.

* Stop the engine and disengage drive to attachments -

(a) before refuelling
(b) before making height adjustment unless adjustment can be made from the operator's position
(c) before clearing blockages
(d) before checking, cleaning or working on the mower
(e) after striking a foreign object (inspect the mower for damage and make repairs before restarting and operating the equipment) and
(f) if machine starts to vibrate abnormally (check immediately).

* Disengage drive to attachments when transporting or not in use.

* A mower operator should be in good mental health and not under the influence of any drug or alcohol which might impair vision, co-ordination or judgement.
* Never mow while barefoot or wearing open sandals, or thongs. Wear long trousers and heavy shoes.

* It is advisable to wear suitable eye protection when operating a mower.
* Mow only in good daylight.
* Before using, always visually inspect to see that blades, blade bolts and cutter assembly are not worn or damaged.
* Replace worn or damaged blades and bolts in sets to preserve balance.

DAMAGED BLADES AND WORN BOLTS ARE MAJOR HAZARDS

* Check all nuts, bolts and screws often, always be sure the mower is in a safe operating condition.
* Keep safety devices (guards and switches) in place and in working order.
* Never use the mower unless the grass catcher, or guards provided by the manufacturer, are in position.
* Ensure any spare parts used comply with the original manufacturer's recommendations and specifications.
* Replace worn or faulty silencer.
* Keep engine free of grass, leaves or excessive grease. These can be a fire hazard.
* Refuel outdoors only. Do not smoke while fuelling engine. Never remove the cap of the fuel tank or add petrol while the engine is running or the engine is hot. Remove fuel cap slowly to relieve any tank pressure. If petrol is spilled, do not attempt to start the engine but move machine away from the area of the spill and avoid creating any source of ignition until petrol vapours have dissipated.
* Check for fuel leaks while refuelling or using the mower. If a fuel leak is found, do not start or run the engine until the fuel leak is fixed and spilled fuel is wiped away.
* Do not operate the engine in a confined space where exhaust fumes (carbon monoxide) can collect.
* Always mount the mower on the opposite side to the discharge chute.
* Start the engine carefully with the cutting means disengaged.
* Do not over-speed the engine or alter governor settings. Excessive speed is dangerous and shortens mower life.
* Stop the engine whenever you leave the mower, even for a moment.
* Store the mower in a well-ventilated room away from naked flames such as may be found in hot water heaters.
* Do not lend or sell the mower without the Owner's Manual.
