Ryobi RY18LMX46A-250 - Battery-powered lawn mower - 2x 18V/5Ah - 46 cm cutting width

The Ryobi RY18LMX46A-250 battery-powered lawn mower is designed for lawns of approximately 500 s.q. m. It is powered by two 18 V ONE 5.0 Ah batteries that work simultaneously to provide high power and extended runtime. The brushless motor constantly adjusts the speed of the blades according to the density of the grass, offering optimal efficiency and consumption.

The cutting width is 46 cm, ideal for reducing the number of passes when working on medium to large surfaces.The cutting height can be centrally adjusted to 10 positions, from 25 to 100 mm, using a single-handed lever. The 55-litre grass collector reduces the frequency of emptying and a plug for the mulching function is also included.

The telescopic handle is height-adjustable and folds vertically for storage in small spaces. The lawn mower is part of the ONE system: the included batteries and battery charger are compatible with other Ryobi tools in the range.

Key benefits include the long runtime provided by the series batteries, the power of the brushless motor, the versatility of the centralised height adjustment system, and the design for practical use and space-saving storage.

• Dual 18 V 5.0 Ah battery: provides extended runtime and increased power; battery charger and batteries included.
• Brushless motor: adjusts blade speed to suit grass conditions; ensures consistent, long-lasting performance.
• 10-position central height adjustment: from 25 to 100 mm; convenient to use with one hand.
• 55-litre grass collector + mulching: reduces emptying frequency and allows natural fertilisation with mulching plug.
• Telescopic handle and vertical folding: for compact storage; height-adjustable for operating comfort.

The 18 V, 5 Ah batteries are located in the centre of the front part .

Simply lift the protective cover and remove the batteries to recharge them.

The 18V lithium-ion battery can be recharged at any time (like modern smartphone batteries, it has no memory effect) so that it is always ready for use. It lasts on average 3 times longer than a normal battery. The battery is equipped with a convenient charge indicator and an activation button to prevent the tool from being switched on accidentally.

Equipped with a protective key to prevent unauthorised operation.

Advantages of the battery-powered electric motor

• More reliable than a combustion engine, thanks to its electric motor. It has no spark plugs, filters, fuel lines, carburettors, etc., i.e. components that are prone to problems
• Much lighter
• Zero maintenance, for the same reasons as above
• Lower consumption and drastically reduced operating costs compared to combustion models (cutting can be carried out with just a few pence worth of electricity). Furthermore, there is no need to always procure fuel (which should always be fresh).
• Zero vibrations, again thanks to the electric motor. On the other hand, almost all combustion systems, which are not equipped with an anti-vibration system on steel springs, have a very high degree of vibration, making work very uncomfortable
• Zero fumes, zero damage to the environment and, above all, to the health of those who use it
• Much quieter and therefore more pleasant to use than combustion engines

The machine is a traditional 3-in-1 model with rear discharge, collection bag and mulching.

BAG COLLECTION:

allows you to collect grass in the special 55-litre grass collector. The basket is equipped with a handle for removal.

REAR DISCHARGE SYSTEM:

allows you to cut the grass without using the grass collector, depositing it directly at the rear of the lawn mower.

MULCHING CUTTING:

using the mulching plug allows you to deposit the grass clippings to fertilise the soil

Centralised cutting height adjustment: a single lever adjusts all 4 wheels simultaneously and synchronised.

10 cutting heights ranging from 25 mm to 100 mm according to the operator's needs.

Plastic housing with carrying handle located on the top of the machine.

The lawn mower weighs 19.5 kg (without batteries), making it very light and compact.

The handle can be easily removed for storage or transport using the two knobs. Its length is also adjustable.

The main controls are located on the handlebar. To operate the machine, press the central button and simultaneously press the two start buttons.

The handlebar is also adjustable to two different heights.

The machine is supplied with:

* The batteries can be used

• In series
• The voltages (V) are added together
• The capacity is NOT added together (Ah)

LONGER LIFE: up to 3 times longer than traditional nickel-cadmium batteries, reducing the need for recharging during long periods of use.
Ideal for medium to large gardens.

FULL CHARGE FOR THE ENTIRE LIFE OF THE BATTERY: the charge of lithium-ion batteries does not fade. Unlike nickel-cadmium batteries, whose power gradually decreases, lithium battery cells maintain constant power throughout the entire cycle. You get virtually the same charge from start to finish, with no reduction in motor speed. The battery operates at full
power until it is completely depleted.

LONG CHARGE LIFE: Lithium batteries boast 3-4 times more recharges than traditional nickel-cadmium batteries, as well as longer storage times with
less charge loss. With lithium batteries, you can get up to 2,000 charge cycles!

LESS WEIGHT: Lithium batteries offer the best power-to-weight ratio. On average, they weigh 1/3 of nickel-cadmium batteries.

ENVIRONMENTALLY FRIENDLY: Lithium battery-powered tools are recyclable and are produced without heavy metals.

NO MEMORY EFFECT: Lithium batteries can be recharged at any time without any negative memory effect, offering maximum power even after hundreds of charge cycles.
A few minutes of charging are enough to provide the power needed to complete the job.

LOW DISCHARGE RATE: Low run down rate (up to 5 times lower than nickel-cadmium batteries) so your tool will be ready to use even after months of non-use.

BATTERY CHARGER: Lithium battery chargers reduce energy consumption by an average of 35%.

The actual mowing area may be significantly lower than the value declared by the manufacturer, which is calculated under standard operating conditions with dry grass of medium to low height. When cutting tall or wild grass, not maintained in an English lawn style, as well as grass that is damp or particularly dense, the workload increases and the motor requires higher energy consumption, resulting in a reduction of the effective battery autonomy.

The value declared by the manufacturer is instead fully reliable under favorable mowing conditions, namely on a regularly maintained lawn with dry grass that is not excessively tall and not wild, corresponding to the standard conditions used in laboratory testing.

When mowing is carried out regularly, cutting a limited and well-maintained layer of grass, preferably in the afternoon when the lawn is almost free of moisture, operating performance may be in line with the declared figures and, in some cases, even higher than stated by the manufacturer.

The cutting mode also affects energy consumption: grass collection and mulching require greater blade effort compared to rear discharge. The condition of the blade also plays a role, as a dull edge increases friction and reduces the number of square meters that can be effectively mowed on a single charge.

Other factors depend on ground conditions. Slopes and uneven terrain require higher torque, and activation of the drive system (if present) leads to continuous energy absorption, significantly reducing effective working time. Non-ideal temperatures, battery age, and repeated restarts or tight maneuvers further reduce the available autonomy.

Under non-optimal operating conditions, the difference between the declared mowing area and the actual workable surface therefore originates from the increased load placed on the motor, blade, and drive system.

The following shows the achievable mowing areas based on the battery capacity used:

The lawn mower is designed and intended exclusively for cutting grass in garden areas (and not on other types of terrain). The surface must be level, free from irregularities, stones, or other solid objects, and covered with maintained lawn grass (therefore, not uncultivated or spontaneous vegetation). Grass should be cut regularly and must not be allowed to grow beyond 25–30 cm, as most lawn mowers are no longer capable of cutting at this height. Slopes exceeding 15% (equivalent to 9°) must be avoided, except when using 4x4 models.

For heavier-duty tasks involving spontaneous vegetation, grass taller than the above-mentioned limits, or rougher surfaces than a garden, please consider alternative product categories such as Petrol Flail Mowers or Brush Cutters.

Furthermore, grass must only be cut when both the lawn and the underlying soil are completely dry. Mowing should be carried out exclusively in dry weather, well away from periods of rain or irrigation, and preferably in the afternoon, when the grass is no longer affected by morning humidity. Wet grass tends to bend under the blades, which reduces cutting efficiency, increases the risk of clogging inside the deck, and subjects the engine to excessive strain.
