The following safety precautions must be observed at all times. Please read them carefully.

TRAINING

  1. Read the instructions carefully. Get familiar with the controls and proper use of the equipment. Learn how to stop the engine quickly
  2. Only use the lawnmower for the purpose for which it was designed, i.e. for cutting and collecting grass. Any other use can be hazardous, causing damage to the machine. Examples of improper use may include, but are not limited to:
    • transport of people, children or animals on the machine;
    • being transported by the machine;
    • using the machine to tow or push loads;
    • using the machine for leaf or debris collection;
    • using the machine to trim hedges, or for cutting vegetation other than grass;
    • use of the machine by more than one person;
    • using the blade on surfaces other than grass.
  3. Never allow children or people unfamiliar with these instructions to use the lawnmower. Local regulations may restrict the age of the operator.
  4. Never use the lawnmower:
    • When people, especially children, or pets are nearby.
    • If the operator has taken medicine or substances that can affect his ability to react and concentrate.
  5. Remember that the operator or user is responsible for accidents or hazards occurring to other people or their property.

PREPARATION

  1. While mowing, always wear sturdy footwear and long trousers. Do not operate the equipment when barefoot or wearing open sandals.
  2. Thoroughly inspect the area where the equipment is to be used and remove all objects which may be thrown by the machine or damage the cutter assembly and the engine (stones, sticks, metal wire, bones, etc).
  3. WARNING: DANGER! Engine fuel is highly flammable:
    • Store fuel in containers specifically designed for this purpose.
    • Refuel using a funnel and outdoors only. Do not smoke while refuelling or whenever handling the fuel.
    • Add fuel before starting the engine. Never remove the cap of the fuel tank or add fuel while the engine is running or when the engine is hot.
    • If fuel is spilt, do not attempt to start the engine but move the machine away from the area of spillage and avoid creating any source of ignition until the fuel has evaporated and the vapour dispersed.
    • Replace all fuel tanks and containers caps securely.
  4. Substitute faulty silencers. Never use the machine without a silencer.
  5. Before use, always inspect the machine, especially the condition of the blades, and check that the screws and cutting assembly are not worn or damaged. Replace worn or damaged blades and screws in sets to preserve balance.
  6. Before mowing, attach the discharge opening guards (grass-catcher or stone-guard).

OPERATION

  1. Do not operate the engine in a confined space where dangerous carbon monoxide fumes can collect.
  2. Mow only in daylight or good artificial light.
  3. If possible, avoid operating the equipment in wet grass.
  4. Always be sure of your footing on slopes.
  5. Walk, never run and do not allow yourself to be pulled along by the lawnmower.
  6. Mow across the face of slopes, never up and down.
  7. Exercise extreme caution when changing direction on slopes..
  8. Do not mow on slopes of more than 20°.
  9. Exercise extreme caution when pulling the lawnmower towards you
  10. Stop the blade if the lawnmower has to be tilted for transportation when crossing surfaces other than grass, and when transporting the lawnmower to and from the area to be mowed.
  11. Never operate the lawnmower with defective guards, or without safety devices, such as the stone-guard and/or grass-catcher, in place.
  12. Do not change the engine governor settings or overspeed the engine.
  13. On power-driven models, disengage the drive clutch before starting the engine.
  14. Start the engine carefully, following the instructions and keeping feet well away from the blade.
  15. Do not tilt the lawnmower when starting the engine. Start the engine on a flat surface that is free of obstacles and tall grass.
  16. Do not put hands or feet near or under rotating parts. Keep clear of the discharge opening at all times.
  17. Never pick up or carry a lawnmower while the engine is running.
  18. Stop the engine and disconnect the spark plug wire:
    • Before carrying out any work underneath the cutting deck or before unclogging the chute;
    • Before checking, cleaning or working on the lawnmower;
    • After striking a foreign object. Inspect the lawnmower for damage and make repairs before restarting and operating the lawnmower.
    • If the lawnmower begins to abnormally vibrate (Immediately look for the cause of the vibrations and contact your local Dealer).
  19. Stop the engine:
    • Whenever you leave the lawnmower unattended. Remove the key from models with electric starters.
    • Before refuelling.
    • Every time you remove or replace the grass-catcher.
    • Before adjusting the grass cutting height.
  20. Reduce the throttle before turning off the engine and turn the fuel off when you have finished mowing, following the instructions in the engine handbook.
  21. When mowing, always keep to a safe distance from the rotating blade. This distance is the length of the handle.

MAINTENANCE AND STORAGE

  1. Keep all nuts, bolts and screws tight to be sure the equipment is in safe working condition. Regular maintenance is essential for safety and performance.
  2. Never store the equipment with fuel in the tank inside a building where vapour may reach a flame or a spa,,rk or a source of extreme heat.
  3. Allow the engine to cool before storing it in an enclosed space.
  4. To reduce the fire hazard, keep the engine, exhaust silencer, battery compartment and fuel storage area free of grass, leaves, or excessive grease. Do not leave containers with grass cuttings in rooms.
  5. Check the stone-guard and grass-catcher frequently for wear and deterioration.
  6. If the fuel tank has to be drained, this should be done outdoors and when the engine is cool.
  7. Wear strong work gloves when removing and reassembling the blade.
  8. Keep the blade balanced during sharpening. All operations on the blade (dismantling, sharpening, balancing, remounting and/or replacing) require a certain familiarity and special tools. For safety reasons, these jobs are best carried out at a specialised centre.
  9. For safety reasons, never use the machine when it has worn or damaged parts. Parts are to be replaced and not repaired. Use genuine spare parts. Parts that are not of the same quality can damage the equipment and impair your safety.
  10. If the machine is not going to be used for 28 days or more, please drain all fuel from the machine. Stale fuel can cause damage to the carburettor.

TRANSPORTATION AND HANDLING

  1. Whenever the machine is to be handled, raised, transported or tilted you must:
    • wear strong working gloves;
    • grasp the machine at the points that offer a safe grip, taking account of the weight and its distribution
    • Use an appropriate number of people for the weight of the machine and the characteristics of the vehicle,  or the place where it has to be placed or collected.
  2. During transport, fasten the machine securely with ropes or chains.

HOW TO GET MOWING

Your Mountfield lawnmower does not contain petrol or oil,,  il and these must be added before use.

Running the mower with insufficient oil can cause serious damage to the engine and will invalidate your warranty.

Warning sign NEVER TIP THE MOWER ONTO ITS SIDE,, AS THIS WILL FLOOD THE AIR FILTER WITH OIL.

To access the underside of the machine, lift the front wheels by lowering the handle to the ground.

Carefully remove the mower from the carton and read these Operating Instructions. An Owner’s Manual for the engine is also included. Please read this before starting the engine.

Warning sign WARNING – Unpacking and completing the assembly should be done on a flat and stable surface, with enough space for machine handling and its packaging, always making use of suitable equipment.

Disposal of the packaging should be done in accordance with the local regulations in force.

HANDLE ASSEMBLY (Figure 1)

  • Insert the lower parts of the handle (1) and (2) into the respective holes and fasten them in place using the screws (3) and the washers (4) supplied. Apply the two caps (5) to the ends of the two lower parts of the handle (1) and (2).
  • Attach the upper part of the handle (6) to the lower parts using the knobs (7) and the nuts and bolts suppliedd,as shown.
  • Engage the Operator Presence Control (OPC) lever by pulling and holding it the orderto release the engine brake. Pull the starter cord (8), and fit it into the cord guide (9) as shown. Tighten the nut (10) using a 10mm spanner. Failure to use the cord guide will result in premature cord wear.
  • Secure the control cables using the clamp (11). Take care that the cables are not secured too tightly (this may impair how the mower operates) or impair the removal of the grass collector. The clutch cable and control lever are only fitted to models with power drive (SP414).

GRASS COLLECTOR

  • Insert the frame into the bag and attach the plastic clips to the frame using a screwdriver, as shown in the drawing (Figure 2).
  • Ensure that the plastic clips are located on the upper front part of the frame (Figure 3).
  • To fit the grass collector onto the mower, lift the rear deflector flap and hook the collector onto the pegs on the rear of the mower (Figure 4).

STARTING YOUR MOWER

Read and understand the Safety Precautions before using your mower.

  • Put Mountfield 4-stroke, or an SAE 10W-30 oil, in the oil filler (Figure 5). Do not overfill, the oil tank capacity is 0,45 litres. Mountfield oil, part number MX855, is available from any Mountfield stockist or B&Q store.
  • Fill the fuel tank with UNLEADED petrol. Use only clean, fresh petrol – stale fuel may contain deposits that will clog the carburettor. Unleaded fuel can start to go stale after just 28 days. Do not overfill; the petrol level should be below the bottom of the fuel tank neck. Do not over-tighten the fuel cap. The fuel cap breathes through the threads of the cap;  over-tightening can cause the engine to cut out.
  • Ensure that the spark plug lead is securely connected to the spark plug. Mountfield SP414 Self-Propelled Lawn Mower-8
  • Press the PRIMER button 3 times to prime the carburettor (Figure 6).
  • Pull and hold the Operator Presence Control (OPC) lever against the handle to disengage the engine brake.
    THE ENGINE WILL NOT START, OR CONTINUE TO RUN, UNLESS THE OPC LEVER IS HELD AGAINST THE HANDLE
  • Pull the starter cord with a strong, smooth pull. Do not remove the pull cord from the guide.
  • When the engine starts let go of the pull cord.
  • To engage the drive to the rear wheels, Self-Propelled models, pull and hold the clutch lever against the handle.
  • To stop the drive, release the clutch lever.
    NOTE: It is not normally necessary to use the “PRIMER” button when starting a warm engine.

STOPPING YOUR MOWER

  • Release the Operator Presence Control (OPC) lever; this will engage the engine brake and operate the ignition safety cut-out device.

ADJUSTING THE HEIGHT OF THE CUT

The height of cut adjustment not only determines the length of the cut grass, but it also controls the airflow,, which carries clippings into the collector. If the discharge chute becomes blocked, increase the airflow by raising the height of cut. To prevent blockages when cutting long, thick grass, set the adjustment to the highest setting and cut the grass; then cut it again on a lower setting.

Mountfield SP414 Self-Propelled Lawn Mower-9

To adjust the height of cut:

  • Stop the engine and disconnect the spark plug
  • Put the mower on a level surface
  • Adjust the cutting height lever by pulling outwards and moving into the required position (Figure 7)
  • All 4 wheels must be at the same height

BEFORE EACH USE

  • Always ensure that the mower is in a safe working condition. Inspect the cutter blade for damage; check safety devices and guards; check that all nuts, bolts and screws are secure.
  • Check the oil level as follows:
    1. Remove the oil filler cap and wipe the dipstick clean (Figure 8). Mountfield SP414 Self-Propelled Lawn Mower-10
    2. Refit the dipstick into the filler neck without screwing it down.
      Remove the dipstick and check the oil level; oil should be at the FULL mark. The oil tank capacity is about 0,4litressre or 20 fluid oz.
    3. If the oil level is,, loadd Mountfield oil part number MX855 or a SAE 10W oill, too the upper limit on the dipstick. Do not overfill; the oil level should not be above the FULL mark.
  • Fill the fuel tank with unleaded petrol. Do not overfill; there is no need to fill the tank to the top. The fuel tank needs only to contain enough fuel to complete the day’s mowing. If you run out of fuel, refilling must only be carried out once the engine has cooled. Fuel stored within the .machine for 28 days or more can go stale and should be drained before further use.

MAINTENANCE

Stop the engine and disconnect the spark plug lead before working on the machine.

Warning sign DO NOT TIP THE MOWER ONTO ITS SIDE AS THIS WILL FLOOD THE AIR FILTER WITH OIL.

To access the underside of the machine, lift the front wheels by lowering the handle until it rests on the ground.

CUTTER BLADE

Examine the cutter blade regularly for wear or damage.

  • A slightly worn blade can be re-sharpened by your local dealer
  • If the blade is damaged,, it should be replaced. Replacement blade kits are available from your Mountfield stockist.
    The part number for the blade kit is MS1199. If in doubt,, refer to your dealer, or telephone 0845 601 4221. Blade must always be marked with part number GGP 81004360/3.

ENGINE

An engine Manufacturer’s Owner’s Manual is supplied with your mower. Please read this, it provides detailed information on engine operation, maintenance and battery care. Repair work other than routine maintenanceshould be carried out by an authorised dealer.

STORAGE

A little time spent on your mower after use will ensure many years of reliable mowing.

To access the underside of the cutter deck, ensure that the spark plug lead is disconnected. Then lift the front wheels by lowering the handle until it rests on the ground. Do not tip the mower onto its side, as this will flood the air filter with oil. Failure to maintain and care for your engine may invalidate the machine’s guarantee. Please see the guarantee statement for full terms and conditions.

AFTER EACH USE

  • Remove any grass pulp from the underside of the cutter deck using a non-metallic instrument such as a piece of wood. Take care not to damage the paintwork.
  • Examine the cutter blade for any damage. A damaged blade may upset the balance of your mower and cause excessive vibration. If in doubt, refer to your dealer.
  • Inspect the grass collector and clean it if necessary. If the mesh becomes clogged airflow will be reduced and impair grass collection.
  • The handle can be folded down to reduce the amount of storage space required. Take care not to trap any of the operating cables when folding or unfolding the handle.
  • Store the mower in a clean, dry area well away from any naked flames, sparks or source..ssurce

LONG TERM – (if you are not using your mower for more than 28 days)

  • Give the machine a thorough clean, paying particular attention to the underside
  • Lubricate all moving parts
  • Empty the fuel tank either by running the mower out of fuel or by tipping the machine backwards and onto the back left wheel to drain the fuel into a suitable container. To drain the carburett,,or it is necessary to slacken the drain screw. The drain screw is situated under the carburettor on the float bowl (see diagram page 4). A bolt holds the bowl in place on the very bottom, but on an angle slightly closer to you is another bolt with a red washer. This is the drain screw.

Mountfield SP414 Self-Propelled Lawn Mower- FAQs

What are the common problems with Mountfield mowers?

Common issues include low or old fuel, blocked filters, dirty or loose spark plugs, and engine blockages. Regular maintenance, cleaning, and fresh fuel usually resolve these problems.

Is the Mountfield SP414 a Honda engine model?

No. The SP414 typically uses a Mountfield ST120 or ST140 4-stroke engine, though some higher-end Mountfield models use Honda engines for added performance and fuel efficiency.

How much oil does a Mountfield SP414 take?

The SP414 requires 0.5 liters of SAE 30 or 10W-30 engine oil. Always check the dipstick to ensure the oil is at the correct level before starting the mower.

Are Mountfield mowers 2-stroke or 4-stroke?

Most Mountfield mowers, including the SP414, feature 4-stroke engines. These are more fuel-efficient, quieter, and longer-lasting compared to 2-stroke engines.

Where are Mountfield lawn mowers made?

Mountfield began production in Maidenhead, England, in 1962. Today, the brand is part of the STIGA Group, which manufactures and distributes garden machinery across Europe.

What type of fuel does the Mountfield SP414 use?

It uses unleaded petrol (minimum 90 RON). Always avoid using old or mixed fuel and never add oil to the petrol — 4-stroke engines have a separate oil compartment.

Can I use 5W30 instead of 10W30 oil in my mower?

Yes. Both 5W30 and 10W30 oils are suitable for Mountfield mowers across most temperatures. However, 10W30 is ideal for warmer conditions and regular use.

Why does my Mountfield mower cut out during mowing?

A blocked air filter, dirty spark plug, or old fuel can cause the mower to stop. Clean or replace the air filter, check the plug, and ensure proper ventilation under the deck.

Is Mountfield the same as STIGA?

Yes, Mountfield is part of the STIGA Group, a European brand family that also includes ATCO, Alpina, and Castelgarden — known for high-quality garden machinery.
