Manufacturer specifications
Greenworks identifies the UK/EU kit as model 2501907UC. Its product page lists a 40V battery platform, 35 cm cutting width, 40L grass bag, five cutting-height positions and a 15 kg product weight. The bundle displayed for the K2X contains the mower, two 2Ah batteries and one charger.

The mower is push-drive rather than self-propelled. That matters more than the nominal voltage if your lawn has slopes or you regularly push through dense, wet growth: the machine does not drive itself up the incline. Greenworks describes two clipping options, collection and mulching, but the box contents and discharge setup should be verified on the exact unit.
There is a product-page inconsistency on the lowest cut. The feature summary states 25–70 mm, while the technical table states 20–70 mm. The five-position setting and 70 mm maximum appear in the manufacturer's description. Do not use the lower figure as a purchasing requirement until you have checked the operator manual or tried the adjustment on the exact mower.
What the K2X kit includes
The suffix matters. Greenworks names the K2X kit as a mower plus two 2Ah batteries and one charger. A bare-tool version or a package with one larger battery may share the G40LM35 model family but would not be the same bundle. When comparing a dealer listing, match the full model code, product reference, batteries and charger rather than relying on a photo of the mower alone.
Greenworks says the mower accepts its 40V batteries and describes the 40V family as compatible across certain tools. Check the manufacturer's battery catalogue for the exact pack and charger, and verify the electrical connector and regional charger plug. “40V” alone does not establish whether a particular battery, charger or regional warranty applies to a specific bundle.
The supplied two 2Ah packs should not be treated automatically as one 4Ah pack. Greenworks publishes its area estimates separately: up to 200 m² with a 2Ah battery and up to 400 m² with a 4Ah battery. The source does not say that these two batteries are combined electrically while mowing, nor does it guarantee 400 m² from the K2X bundle. Ask whether the machine uses the packs one at a time and whether the supplier includes a second charger if uninterrupted mowing matters to you.
Greenworks lists a three-year warranty for the mower and two years for the battery on the UK product page. Treat those as UK page terms, not a promise for a purchase in another country: warranty duration, registration deadlines, commercial-use exclusions and service arrangements can differ by seller and market. Save the receipt and check the current conditions before ordering.
Lawn size, runtime and mowing conditions
Greenworks positions the mower for medium-size lawns and estimates up to 200 m² with a 2Ah battery and up to 400 m² with a 4Ah battery. Those figures are not independent test results and do not say how often the grass was cut, how dense it was, how much slope it had or how much energy was left in the battery. Use them as an initial reference only.
Battery demand can rise when grass is long, damp, dense or allowed to grow between cuts. Slopes, repeated stops, edge work, a full collection bag and a blunt or damaged blade can also change the time available per charge. If the actual lawn is close to the maker's estimate, plan a first cut with a spare charged battery and observe your own conditions before relying on a single charge.
A 35 cm deck is a manageable width for a smaller, shaped lawn and narrow passages, but it requires more parallel passes than a wider deck across a large open area. Measure the narrow gates and storage route as well as the mowing surface. The published 15 kg is tool weight; it does not include the effort of moving the mower across steps or lifting it into a vehicle.
For tall grass, a safer approach is to reduce the height in stages rather than force the mower through a heavy first pass. Use a dry-lawn schedule when possible, empty the collection bag before it becomes difficult to handle, and stop the motor before clearing clippings. Follow the Greenworks manual for the allowed slope and operating conditions; this page does not assign a safe maximum incline.
Cutting height, collection and mulching
The five central height positions let you adjust the deck for the condition of the lawn, but the published minimum needs checking because of the 20 mm versus 25 mm inconsistency. A higher setting is usually the conservative starting point for overgrown grass; make a second pass lower only if the manual and lawn conditions allow it. Do not assume a particular setting from a reseller's summary when it conflicts with the maker's technical table.
Use the 40L collector when you want to remove clippings or when the lawn's condition makes mulching unsuitable. A full bag adds weight and can interrupt work, so check it regularly. Mulching can return finely cut clippings to a lawn, but it works best when the grass is short enough for the mower to process and the clippings are not clumping. Greenworks describes a mulching function, but confirm the required plug or insert is included in the package before relying on it.
GrassCombs are not specified for this model; do not assume edge-cutting performance equivalent to a corded mower that has them. Plan a separate edging pass where the deck cannot reach a wall, bed or fence. For layout decisions across battery and corded equipment, the electric lawn mower guide compares the formats without treating their market variants as interchangeable.
Market and product listing check
The UK and EU manufacturer pages identify the mower as G40LM35K2X / 2501907UC and show the K2X package as two 2Ah batteries plus a charger. Their product copy contains a second discrepancy: the UK height summary says 25–70 mm, while its specification table says 20–70 mm. Confirm the current manual and exact unit before treating either minimum as settled.
This model is documented for the UK/EU market. Its charger plug, warranty, stock status and replacement-part route should be confirmed in the country where it will be used. A 40V platform name alone does not prove that a battery, charger or service plan from another region is compatible.
What to check before buying
- Confirm the exact model reference, 2501907UC, and whether the listing includes two batteries and a charger.
- Check that a push mower and its 15 kg listed weight suit the lawn and terrain.
- Verify the cutting-height range in the manual because Greenworks publishes two different lower limits.
- Confirm local stock, warranty terms, and replacement-part support with the seller in your country.
For readers in North America, compare models sold for that market by exact deck width, drive type, battery pack and warranty. Do not use specifications for a different Greenworks mower as a substitute. For a corded alternative with a similar narrow cutting width, see the separately documented Bosch UniversalRotak 34-405; it is a 230 V European model with different electrical and regional requirements.
Care and storage checks
Use the operator manual for blade removal, cleaning and maintenance intervals. Before inspecting the underside or clearing packed grass, stop the machine and remove the battery as the manual directs. Never reach under the deck while it can start. Keep the blade sharp and undamaged; if it strikes a stone or hard object, stop and inspect the mower before restarting.
Keep the ventilation openings clear and wipe away dry grass from the deck after use. Do not wash the motor or battery compartment with a pressure jet unless Greenworks specifically permits that method. Store the battery and charger in the temperature and moisture conditions described in their manuals, away from metal objects that could bridge the contacts. Check battery condition, charge retention and connector cleanliness before the next season.
Fold the handle only after checking the cable and controls are clear, and choose a storage space that keeps the mower upright and protected from rain. If the model is sold as a bundle, label the batteries and charger with the product so they do not get mixed with packs from another voltage platform. If the mower vibrates unusually or the blade housing is damaged, stop use and contact the seller or authorised service.
