The Hyundai HY42-E40(P) is a 40V, hand-push cordless mower with a steel deck, a 415mm (about 42cm) cutting width and collection, mulching and rear-discharge functions. It could suit a small or medium lawn, but the purchase decision depends on one unresolved issue: Hyundai’s own listing uses contradictory language about whether the battery and charger are included. Cutting-height and battery-capacity details also differ between the manufacturer, manual and CHOICE listings. Treat the advertised package, not just the model name, as the thing to verify. The accessible CHOICE page identifies a 2025 test but does not show its scores, so there is no evidence here for a performance ranking against rival mowers.
What is the Hyundai HY42-E40(P)?
The HY42-E40(P) is a 40V lithium-ion, hand-push lawn mower built around a steel cutting deck. Hyundai describes three operating modes: collecting clippings in the catcher, mulching them back onto the lawn, and rear discharge. CHOICE lists the model as a battery mower with a 42cm cutting width, while Hyundai and the manual specify 415mm (41.5cm), which is the same nominal class expressed with different rounding.
The “Skin” wording needs particular care. Hyundai has a separate skin-only listing, yet another manufacturer page carries a kit-style title and an included-items section while also saying the battery and charger are sold separately. A seller can therefore use the same model family name for materially different boxes. Confirm the exact SKU, battery, charger and catcher shown on the order before treating any price as comparable.
Is the battery and charger included?
Not consistently according to the available listings. The safest assumption is that inclusion is unconfirmed until the seller’s current specification or invoice explicitly names each item.

| Listing or source | What it indicates | Why it matters |
|---|---|---|
| Hyundai page title and included-items section | Presents a battery-and-charger kit; the included-items details identify a catcher, mulching plug, battery and charger. | This is the package a buyer might expect at the kit price. |
| Other copy on the same Hyundai page | Says the battery and charger are sold separately and gives a 2.5Ah/sold-separately battery reference in the specifications. | This conflicts with the kit wording. |
| Separate Hyundai result | Lists a skin-only model and displays $440. | A lower price may represent the mower body only, not a ready-to-mow package. |
| CHOICE listing | Names a 4Ah HY40B4 battery and lists a catcher, mulching plug, battery and charger among supplied items. | This describes a different package configuration from the skin-only result. |
Ask the seller to confirm four individual line items: mower, battery capacity and model, charger, and catcher. Save a screenshot or written reply. If you already own a compatible Hyundai 40V battery, confirm that the charger and battery voltage are accepted for this exact mower; the manual result indicates support for 2.0Ah or 4.0Ah batteries, but it does not establish that every Hyundai 40V pack is interchangeable.
What are the published specifications?
The core electrical specification is consistent, but several figures vary by source. The table keeps the alternatives visible instead of presenting a disputed number as definitive.
| Specification | CHOICE listing | Hyundai listing | Manual result |
|---|---|---|---|
| Power system | 40V lithium-ion battery | 40V lithium-ion | 40V nominal |
| Cutting width | 42cm | 415mm (17in) | 415mm (41.5cm) |
| Cutting-height range | 30–80mm, six positions | 25–75mm, six positions | 25–75mm, six heights |
| Weight | 19kg | 19kg net | 19.9kg including battery |
| Grass catcher | Included | 45L | Not fully established in the retrieved result |
| Battery | HY40B4, 4Ah | Copy mentions 2.5Ah/sold separately and 4Ah in included items | 2.0Ah or 4.0Ah supported |
| Charging time | 45 minutes claimed | Not stated in the cited listing details | Not stated |
| Warranty | Two years | 24-month residential warranty | Not stated |
The 19kg and 19.9kg figures are not necessarily a true contradiction: one may be a net product weight and the other a measured mower with its battery fitted. For lifting or transport, use the 19.9kg including-battery figure as the more conservative planning number unless the seller supplies a version-specific weight.

What cutting width and height should you expect?
The width is effectively 41.5cm; CHOICE rounds it to 42cm. That is wide enough to avoid excessive passes on an ordinary suburban lawn while remaining narrower than many larger petrol or high-voltage machines. The meaningful uncertainty is the height range, not the width.
Hyundai and the manual specify six positions from 25mm to 75mm. CHOICE lists six positions from 30mm to 80mm. A five-millimetre difference at each end can affect a low ornamental cut or a lawn that should be left longer in hot, dry weather. Check the height decal on the actual mower or the revision of the manual supplied with your SKU before choosing it for a specific grass type.

Do not infer that six positions means a particular lever layout or that the highest setting is exactly 80mm on every unit. The number of steps is consistent; the endpoint values are not.
Which mowing modes and accessories are available?
Hyundai describes collection, mulching and rear discharge. The CHOICE supplied-items list includes a catcher and mulching plug, and Hyundai lists a 45L catcher. That combination lets you choose between removing clippings, returning finely cut material to the turf, or discharging behind the mower when collection is unnecessary.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Collection
Use the catcher when you want a clear finish or are dealing with wet, heavy growth that you do not want left on the lawn. The 45L capacity is a published specification, not a guarantee of how often it will need emptying; fill rate depends on grass height, moisture and walking speed.
Mulching
The mulching plug is listed among the supplied items by CHOICE. Mulching works best when growth is not excessively long and the deck is kept clear. The listing does not provide a mulching-performance test, so do not assume it will process every overgrown lawn in one pass.
Rear discharge
Rear discharge is the third mode Hyundai names. No evidence in the supplied material confirms a side-discharge chute, so do not count on side discharge unless it appears in the current box contents or manual for your exact model.

How much lawn can it cut on one charge?
There is no verified runtime or maximum-area figure in the accessible material. CHOICE’s test page includes fields for battery life and maximum lawn size, but the actual results and recommendation are restricted to members. The manufacturer information supplied here also does not state a guaranteed mowing area.

A 4Ah pack stores more charge than a 2.0Ah pack, but that does not translate into a fixed number of square metres without controlled testing. If your lawn is close to the limit of one charge, ask the seller for an area claim tied to the exact battery supplied, or budget for a second compatible pack and the charging time between sessions.
What does the independent CHOICE test establish?
CHOICE identifies 2025 as the test year and lists assessment categories including grass cutting, ease of use, vibration, pushing, handle, controls, height adjustment, battery life, noise, maximum lawn size and catcher performance. The accessible page does not reveal the numerical scores, recommendation or comparative ranking.
Consequently, the existence of a CHOICE test page is not evidence that this mower cuts well, runs quietly, lasts a particular time or beats another model. Treat those outcomes as unknown unless you can view the member-only results or obtain a separate, model-specific test report.
What does it cost?
The available price points describe different listing contexts and should not be compared without confirming the contents of the box.

| Price shown | Source context | Interpretation |
|---|---|---|
| $640 | CHOICE product page, accessed 2026 | A listed product price; the page also identifies a 4Ah battery and supplied charger. |
| $640 | Hyundai page with a kit-style title | Appears to be the battery-and-charger package, but the same page contains conflicting sold-separately wording. |
| $440 | Separate Hyundai skin-only result | Likely a mower-only configuration; battery, charger and final contents must be confirmed. |
Compare total ready-to-mow cost rather than the headline number: mower, battery, charger, delivery, and any additional pack required for your lawn. Also check whether the price is current for your country and whether the warranty applies to residential use there.
What warranty is stated?
CHOICE lists a two-year warranty, while Hyundai states a 24-month residential warranty. Those durations are equivalent on their face, but the accessible details do not establish geography, exclusions, commercial-use coverage, battery-warranty treatment, or who pays freight for a claim. Obtain the current warranty document from the seller or manufacturer and retain proof of purchase.
How should you verify a listing before ordering?
Use this checklist when two listings show the HY42-E40(P) name at different prices.
- Match the complete model code. Check every suffix and punctuation mark, not just “HY42-E40”. A skin-only listing and a kit listing may share the base model name.
- Request a box-contents list. It should explicitly say mower, catcher, mulching plug, battery model and capacity, and charger.
- Confirm battery capacity. Ask whether the supplied pack is HY40B4 4Ah, a 2.5Ah pack, or another specification. Do not rely on a photograph that may show an optional battery.
- Check the charger. A battery-only purchase is not ready to use unless you already have the correct charger. Verify voltage and model compatibility.
- Check the height range on the physical unit or manual revision. Record whether the six positions are 25–75mm or 30–80mm.
- Clarify weight measurement. Ask whether the quoted mass includes the battery; the published figures span 19kg net to 19.9kg with battery.
- Confirm warranty territory and use. Request the 24-month/two-year terms that apply to your address and intended residential use.
- Save the evidence. Keep the seller’s written confirmation and the order page in case the delivered package differs.
Who is this mower best suited to?
It is a plausible fit for a buyer who wants a conventional steel-deck mower, already has access to a compatible 40V battery platform, and values the choice of collection, mulching and rear discharge. The 415mm cutting path balances manoeuvrability with fewer passes than a very narrow mower, while the hand-push design avoids the complexity of a self-propelled drive system.

How does it compare with other cordless mowers?
A fair comparison should use the same evidence for every candidate. The following framework prevents a low skin-only price from appearing better than a complete kit.
| Comparison question | Why it changes the decision | Evidence available for HY42-E40(P) |
|---|---|---|
| Is the battery and charger included? | Determines the true ready-to-mow cost. | Conflicting Hyundai copy; verify the seller SKU. |
| What battery capacity is supplied? | Changes charging frequency and the cost of a spare. | CHOICE names 4Ah; Hyundai copy also mentions 2.5Ah; manual supports 2.0Ah or 4.0Ah. |
| What area does one charge cover? | Indicates whether one pack is practical for your lawn. | No accessible verified area or runtime figure. |
| What is the cutting range? | Important for grass species, seasonal height and recovery after stress. | Six positions, but endpoints conflict between 25–75mm and 30–80mm. |
| How does it handle collection and mulching? | Determines finish, emptying frequency and whether clippings stay on the lawn. | Modes and accessories are listed; independent scores are not accessible. |
| What does it weigh in working condition? | Affects turning, slopes, lifting and storage. | 19kg net is listed; the manual result gives 19.9kg including battery. |
| What warranty and service support apply? | Protects against defects and affects repair cost. | Two-year/24-month residential terms are stated; detailed territory and exclusions require confirmation. |
What should you check on first setup?
Before mowing, compare the delivered parts with the invoice and the current manual. Confirm that the catcher, mulching plug, battery and charger promised by the seller are present; inspect the deck and controls for shipping damage; and charge the battery using the supplied or explicitly compatible charger. Set the cutting height using the mower’s markings rather than assuming the range printed in a different listing.
For the first session, clear stones, sticks and wire from the lawn, use the collection mode if you want to see how quickly the catcher fills, and stop to inspect the deck if cutting becomes uneven or the machine vibrates unusually. Follow the model-specific safety, charging, storage and blade-maintenance instructions in the current manual; those procedures are not fully reproduced in the available result.
Verdict: should you buy the HY42-E40(P)?
Buy it only after the package is confirmed in writing. The mower has a useful 40V platform, steel deck, 415mm-class cut and three listed discharge options, but the battery/charger ambiguity and conflicting height and battery details make headline-price comparisons unreliable. The available CHOICE page confirms a 2025 test exists, not how the mower scored. A complete kit at a clearly stated price can be reasonable for a compatible-platform owner; a skin-only price is not a ready-to-mow bargain unless you already own the required battery and charger.
Frequently Asked Questions
Is 415mm the same as a 42cm cutting width?
Practically, yes. 415mm equals 41.5cm, and 42cm is a rounded presentation of the same nominal cutting class; the difference is a rounding convention rather than an extra half-centimetre of usable deck width.
Does the HY42-E40(P) have side discharge?
Side discharge is not identified in the available Hyundai or CHOICE details. The documented modes are collection, mulching and rear discharge, so treat side discharge as unavailable unless your exact manual or box contents explicitly lists a chute.
Can I use any Hyundai 40V battery in this mower?
Compatibility is not established for every 40V pack. The manual result mentions 2.0Ah and 4.0Ah support, while listings reference other capacities; match the battery model and charger to the mower’s current manual or obtain written confirmation from the seller.
