Short answer: The LM1704E-SP is the Australian-market identity for a 56V brushless, self-propelled EGO mower with a 42cm cutting deck. Australian promotional material describes a kit containing a 5.0Ah battery and charger, while a current retailer listing should be checked to confirm the bundle you will actually receive. It is a potentially practical choice for homeowners who want drive assistance and a narrower deck for smaller or more intricate lawns, but there is not enough verified evidence to promise a particular runtime, hill capability, noise level, cut quality or long-term reliability for this exact variant.
This review separates confirmed model information from figures that belong only to related regional models. That distinction matters because EGO uses different codes for apparently similar 42cm mowers in Australia, Europe and the UK.

What the LM1704E-SP is
EGO Power+ Australia identifies LM1704E-SP as a 42cm self-propelled cordless mower kit. The platform uses a 56V brushless motor, and Australian promotion material associates this exact kit identity with a 5.0Ah battery and charger. Total Tools Australia has also listed the exact LM1704E-SP as a 56V, 5.0Ah, 42cm self-propelled mower kit.

The 42cm figure is the cutting width, not the overall body width. It places the mower in a maneuverable class: narrower than many large domestic decks, but wider than compact edge trimmers and very small push mowers. Whether that is the right size depends on the area you cut, the number of obstacles, access through gates and paths, and how much value you place on self-propelled assistance.
Confirmed specifications and what is not established
| Item | What the available Australian material establishes | Qualification |
|---|---|---|
| Australian model identity | LM1704E-SP | Use this code when checking an Australian listing, invoice or warranty record. |
| Power system | 56V cordless platform; brushless motor described in Australian product material | Exact motor output, blade speed and controller data were not published in the supplied material. |
| Drive | Self-propelled | The exact speed-control arrangement and operating procedure should be confirmed in the current manual. |
| Cutting width | 42cm | The 42cm platform description is also present in related EGO regional documentation. |
| Battery in promoted kit | 5.0Ah battery | Promotional and retailer bundles are volatile; verify the live seller listing. |
| Charger in promoted kit | Charger | Confirm the charger model and whether it is included in the exact offer you are buying. |
| Weight of LM1704E-SP | Not stated in the available exact-variant evidence | Do not substitute the weights published for LM1700E-SP. |
| Runtime or lawn area per charge | Not established | Grass height, moisture, blade condition, slope, drive use and battery age all change the result. |
| Charge time, noise, cut quality and reliability | Not established for LM1704E-SP | These require exact-model documentation or comparable testing. |
This is why a precise “cuts X square metres” claim would be misleading here. No measured runtime or area-per-charge result for LM1704E-SP is established in the available evidence.
LM1704E-SP, LM1700E-SP and LM1702E-SP: why the codes differ
EGO’s regional documentation uses related codes for the same general 42cm self-propelled platform. The Australian material pairs LM1704E-SP with the related LM1700E-SP code. EGO Europe’s manuals index lists LM1700E-SP as a 42cm self-propelled mower and LM1702E-SP as a 42cm self-propelled mower kit. The UK operator-manual listing for LM1700E/LM1700E-SP also gives a 42cm cutting width.
Recommended Free Tools
| Code | Regional context in the available documents | What you can safely conclude |
|---|---|---|
| LM1704E-SP | Australian-market mower-kit identity | This is the code to match when buying in Australia. Australian material associates it with a 5.0Ah battery and charger. |
| LM1700E-SP | EGO Europe and UK related model | 42cm self-propelled mower platform context. It is not proof of identical Australian bundle contents or performance. |
| LM1702E-SP | EGO Europe related kit code | 42cm self-propelled kit context. Regional equipment, warranty and included items may differ. |
The UK manual search listing reports 22kg for LM1700E and 24kg for LM1700E-SP, both without the battery pack and mulching insert. Those are related-model figures, not verified LM1704E-SP measurements. Do not use them to calculate the Australian mower’s lifting weight, transport burden or expected handling.

What should be in the Australian kit?
The strongest Australian bundle evidence describes a 5.0Ah battery and charger alongside the mower. Because the cited promotion is time-sensitive and retailer packages can change, inspect the listing and the carton contents before accepting delivery.
Pre-purchase checklist
- Match the complete code. The listing, box and invoice should say LM1704E-SP, not only a shortened LM1700E or a generic 42cm description.
- Read the “included” line. Confirm that one 5.0Ah battery and a charger are explicitly listed. Do not assume a photograph proves inclusion.
- Check battery condition and warranty terms. Ask whether the battery is new, what Australian warranty applies to the battery and charger, and who handles a fault.
- Confirm accessories. Check whether a grass catcher, mulching insert, side-discharge part or other attachment is included. The available evidence does not establish the exact accessory set for every LM1704E-SP offer.
- Save the model and serial records. Photograph the label and retain the invoice for service or warranty claims.
Is a 42cm deck suitable for your lawn?
A 42cm deck covers 0.42m on each straight pass. A narrower deck generally makes it easier to weave between garden beds, trees, posts and play equipment, and it can fit through tighter gates than a broad residential mower. The trade-off is that a large, open lawn requires more overlapping passes than it would with a wider deck.
Choose this width when maneuverability matters
- Your lawn has many corners, narrow strips or obstacles.
- Storage space or gate width limits the mower’s physical size.
- You prefer a mower that is easier to position at edges and around beds.
- Your cutting area is modest enough that additional passes are acceptable.
Consider a wider alternative when coverage dominates
- You mow a broad, uncomplicated area with few obstacles.
- You want to reduce walking time and turning frequency.
- You regularly collect heavy growth and would benefit from a larger deck, provided the chosen model’s motor and battery system are suited to that load.
Deck width alone does not tell you how quickly a mower will finish. Turning layout, overlap, grass density, slope and whether the drive is engaged can be as important as the nominal 42cm measurement.
How self-propelled drive changes the decision
Self-propulsion moves the mower without requiring you to push its full rolling resistance. That can be valuable on inclines, thick grass and longer sessions, or for anyone who finds pushing difficult. It also reduces the effort of maintaining a steady pace around a lawn.

The assistance is not free. The drive system draws energy while it is engaged, and its usefulness depends on speed control, traction and the terrain. The supplied evidence does not provide an LM1704E-SP runtime comparison with drive switched off versus on, nor does it establish a maximum slope. Therefore, do not assume that the mower will cover a particular area on a charge simply because it is self-propelled.
Questions to ask if your lawn is sloped
- Does the seller or current manual specify an operating limit for slopes?
- Can the drive speed be adjusted to match your walking pace?
- Are the drive controls comfortable to hold while steering around obstacles?
- How will you move the mower when the drive is disengaged, such as during storage or transport?
For a flat, small lawn, self-propulsion may be a convenience feature rather than a necessity. For a sloping block, it can be the feature that determines whether a 42cm mower is usable, but that judgment should be made with the exact manual’s limits and your terrain in mind.
Runtime: what you can and cannot predict
There is no verified LM1704E-SP runtime, mowing-area figure or charge-time result in the available material. A 5.0Ah label identifies battery capacity within the 56V system; it does not translate into one guaranteed number of minutes or square metres.

- Grass species, height, moisture and density.
- Blade sharpness and cutting-height setting.
- How much overlap you leave between passes.
- Whether self-propelled drive is engaged continuously.
- Slope, wheel resistance and frequent stopping or turning.
- Battery temperature, age and charging state.
A practical way to establish your own result
- Fully charge the supplied battery using the included charger and record the starting condition.
- Mow a known section of your lawn under normal conditions, using the cutting height and drive setting you would ordinarily choose.
- Record the area completed, the time spent and the remaining battery indication, if the mower or battery provides one.
- Repeat on a second session with similar grass conditions. Avoid comparing a dry, recently cut section with wet, overgrown grass.
- Use the lower result as your planning figure and leave reserve capacity for unexpected thick patches rather than planning to drain the battery on every mow.
This method gives you a household-specific benchmark without pretending that a manufacturer-style laboratory figure applies to every Australian lawn.

Performance claims that remain open
A review should not turn a product description into a test result. For LM1704E-SP, the available evidence does not establish:
- How evenly it cuts across different grass types.
- Whether it leaves visible striping or scalping on uneven ground.
- How it performs on wet or tall grass.
- Its traction and control on a particular hill.
- Sound level during cutting or charging.
- Time required to recharge the 5.0Ah battery.
- Battery degradation or mower reliability after extended use.
These are not minor omissions if you are choosing between cordless systems. Look for exact-model tests that state lawn conditions, cutting height, drive use, weather, battery age and measurement method. A single unqualified runtime number is less useful than a shorter test that explains those conditions.
First-use and setup checklist
The full operating and safety procedure should come from the current official LM1704E-SP manual. The official manual PDF for the related LM1700E-SP was not available in full through the supplied source material, so exact control sequences and safety limits should not be inferred from another model’s illustrations.

- Charge the battery according to the current Australian manual and charger instructions before the first cut.
- Inspect the deck, blade area, catcher and discharge openings with the battery removed and the mower secured.
- Clear stones, wire, toys and branches from the mowing area.
- Set the cutting height and drive controls only as described by the manual.
- Start on a flat, clear section so you can learn the controls before approaching edges, slopes or obstacles.
- Stop, isolate the battery and follow the manual’s procedure before clearing a blockage, inspecting the blade or changing an attachment.
Maintenance, storage and ownership considerations
Cordless equipment avoids petrol, fuel storage and engine oil, but it still needs routine care. Keep the underside and discharge path free of compacted clippings, inspect the blade for damage, and store the battery and charger in the conditions specified by EGO. Do not wash electrical components with a hose unless the manual explicitly permits it.

Blade condition affects both appearance and energy use. A damaged or dull blade can produce a poor finish and force longer mowing sessions. Before sharpening, removal or replacement, follow the exact isolation steps in the LM1704E-SP manual and use only approved parts.
For storage, protect the mower from rain and damp, keep the battery away from extreme heat, and avoid leaving the battery in a discharged state if EGO’s instructions advise otherwise. Keep the charger’s ventilation area clear and retain purchase records for warranty support.
How to compare the LM1704E-SP with another cordless mower
A fair comparison needs more than voltage or deck width. Use the same questions for every candidate and separate published specifications from your own observations.
| Comparison point | Why it matters | Evidence to request |
|---|---|---|
| Cutting width | Determines maneuverability and the number of passes on open lawn. | Exact deck width and, ideally, the mower’s overall dimensions. |
| Drive assistance | Changes effort on slopes and may affect energy use. | Self-propelled status, speed adjustment and any stated slope limit. |
| Battery and charger | A “tool-only” price can be misleading. | Battery capacity, charger inclusion and the precise models supplied. |
| Weight | Affects lifting, storage and manual pushing. | Exact-variant weight, with or without battery clearly stated. |
| Runtime | Determines whether one session can finish your lawn. | Test conditions, grass state, drive setting and area measured. |
| Cut and collection | Influences the finish and emptying frequency. | Comparable tests on similar grass, not an unsupported promise. |
| Charging | Matters when you mow frequently or have multiple areas. | Published charge time for the supplied battery and charger. |
| Warranty and service | Important for batteries, electronics and seasonal use. | Australian terms, exclusions and the service contact. |
| Total price | Reveals the real cost of entering the battery platform. | Mower, battery, charger and required accessories in the same offer. |
On the evidence available here, LM1704E-SP scores clearly on a 42cm self-propelled format and a promoted 5.0Ah battery-and-charger kit. It cannot be ranked on runtime, noise, cut quality, weight or durability without exact measurements.
Who should buy the LM1704E-SP?
It makes sense when
- You are buying in Australia and the seller confirms the LM1704E-SP code.
- You want self-propelled assistance rather than a conventional push mower.
- A 42cm deck suits your gates, storage and obstacle-filled lawn.
- The current package genuinely includes the 5.0Ah battery and charger at a price you consider acceptable.
- You are comfortable establishing your own runtime rather than relying on an unsupported area claim.
Look elsewhere or investigate further when
- You need a verified large-lawn runtime or a documented hill rating.
- You require a very light mower for frequent lifting, but the exact LM1704E-SP weight is not available.
- You expect the Australian model to have identical accessories, weight or warranty terms to an LM1700E-SP or LM1702E-SP sold overseas.
- You are comparing a bare-tool offer with a complete kit and have not added the cost of a battery and charger.
Verdict
The EGO Power+ LM1704E-SP is best understood as an Australian 42cm, 56V brushless, self-propelled mower kit rather than as a universally documented global model. Its strongest confirmed buying points are the maneuverable deck, drive assistance and the Australian promotion’s inclusion of a 5.0Ah battery and charger. Its biggest unknowns are the ones that determine real-world mowing performance: exact weight, runtime, charge time, hill behavior, noise, cut quality and long-term reliability.
Buy it when the current Australian listing confirms the complete kit and its 42cm self-propelled format matches your lawn. Before committing, verify the bundle, warranty and manual, then judge runtime from your own grass and terrain instead of treating figures from related regional model codes as LM1704E-SP test results.
