STIHL RMA 453 PV cordless lawn mower
The STIHL RMA 453 PV is a wide-cut, self-propelled cordless lawn mower designed for medium to large lawns. Its 51cm / 20-inch cutting width, variable-speed Vario drive and two AP battery slots make it particularly suitable for customers who want the coverage and assistance of a substantial petrol mower without fuel, pull starting or exhaust fumes at the point of use.
The mower can collect, mulch, side discharge or cut and drop, giving you the flexibility to change how you manage the grass throughout the season. It also includes a 55-litre folding grass box, central cutting-height adjustment from 20 to 100mm and an electronic handle display showing battery and operating information.
Please note: this listing is for the mower only. A compatible STIHL AP System battery and charger are required and are sold separately.

Who is the STIHL RMA 453 PV best for?
This mower is a strong choice if you have a substantial lawn and want a cordless machine that covers ground quickly. The 51cm cutting deck reduces the number of passes required, while the self-propelled drive takes much of the effort out of mowing longer sections and gentle slopes.
It is particularly suitable for:
- Medium to large lawns where a narrow push mower would take too long
- Customers replacing a self-propelled petrol lawn mower
- Gardens with longer runs, open areas or gentle slopes
- Existing owners of STIHL AP System batteries
- Users who want the choice of collecting, mulching or side discharging
- Customers who value low-noise, push-button cordless operation
For a smaller or more intricate garden, a narrower mower may be easier to turn and store. You can compare this machine with other STIHL lawn mowers or browse our complete range of cordless lawn mowers.
Why Masseys recommends the STIHL RMA 453 PV
At Masseys, we recommend the RMA 453 PV to customers who want a genuinely substantial cordless mower rather than a lightweight machine intended only for a small lawn.
Its main advantage is the combination of a wide 51cm cut, self-propelled assistance and flexible grass management. You can collect during normal mowing, mulch when conditions are suitable, use side discharge on longer grass or remove the grass box and cut and drop.
The two battery slots are another practical advantage. When two compatible AP batteries are fitted, the mower can switch automatically from the first battery to the second, reducing interruptions on a larger lawn.
We also like the mono-handle design because it leaves one side of the grass box unobstructed, making the box easier to remove and empty.
It is important to understand that this is a substantial machine. At approximately 29kg without a battery, it is not the mower we would choose if it must regularly be carried up steps or lifted into a vehicle. The Vario drive makes it easier to operate while mowing, but customers with small, tight gardens may prefer a more compact model.
This is also a conventional wheeled mower rather than a rear-roller mower. Customers who regard strong lawn stripes as their main priority should ask us about suitable rear-roller alternatives.
Key features of the STIHL RMA 453 PV
51cm cutting width
The 51cm / 20-inch cutting deck allows the mower to cover open areas efficiently. It is wider than many domestic cordless lawn mowers and is well suited to gardens where reducing mowing time is a priority.
Variable-speed Vario self-drive
The rear-wheel drive can be adjusted to suit your walking pace, the terrain and the condition of the grass. This is especially useful on longer lawns and slopes, where pushing a mower of this size could otherwise become tiring.
Two battery slots with automatic switchover
The RMA 453 PV can hold two compatible STIHL AP batteries. With two batteries fitted, sequential discharge allows the mower to switch automatically to the second battery when the first is depleted.
This makes it possible to continue mowing without stopping to move a battery between slots.
Four ways to manage the grass
The mower can be configured for four different mowing methods:
- Cut and collect: clippings are collected in the 55-litre grass box
- Mulching: finely chopped clippings are returned to the lawn
- Side discharge: longer grass is discharged through the integrated side flap
- Cut and drop: mow without the grass box fitted
The ability to change methods makes the mower useful across different grass conditions and seasons.
20–100mm central cutting-height adjustment
A single central control adjusts the cutting height between 20 and 100mm. This broad range allows you to leave the grass higher during difficult conditions or gradually reduce overgrown grass over several cuts.
55-litre folding grass box
The folding grass-collection box has a fill-level indicator so you can see when it needs emptying. Its design allows the box to open widely, making it easier to remove compacted clippings.
Height-adjustable mono-handle
The handle is mounted on one side, leaving clear access to the grass box. It can be adjusted to suit the operator and folded for transport or more compact storage.
Digital handle interface
The controls and display provide information including battery charge, selected operating mode and speed settings. This allows the main mower settings to be checked and adjusted from the handle area.
Eco mode and efficient blade design
Eco mode adjusts motor output to the mowing conditions, helping to conserve battery power when maximum output is not required. The flow-optimised blade is designed to reduce unnecessary air resistance and make efficient use of the available battery energy.
Robust polymer deck
The double-layered polymer housing is designed to be strong, UV resistant and rust free while remaining lighter than a comparable steel mower deck.
Which battery should I use with the RMA 453 PV?
The mower uses batteries from the professional STIHL AP System. This means the battery can also be shared with a wide range of compatible STIHL chainsaws, hedge trimmers, brushcutters, blowers and other garden machinery.
STIHL publishes an approximate mowing area of up to 450m² using one AP 300 S battery and up to 900m² using two AP 300 S batteries. These are guideline figures rather than guaranteed results.
Actual coverage will vary according to:
- Grass length, thickness and moisture
- Selected cutting height
- Whether the mower is collecting, mulching or side discharging
- Terrain and use of the self-propelled drive
- Battery age, temperature and charge condition
- Walking speed and mowing technique
STIHL’s current technical information lists the AP 500 S battery as its recommended battery for this mower. The AP 300 S battery remains a compatible and popular option, particularly for customers who already own AP 300 S batteries or who want to use STIHL’s published 450m² and 900m² area guidance.
If you are buying your first AP System machine, our team can help you choose between the AP 300 S and AP 500 S based on your lawn size, terrain and the other STIHL tools you intend to use.
You will also need a compatible charger. View the available STIHL battery chargers, including standard, quick and high-speed options.

Frequently asked questions
Does the STIHL RMA 453 PV include a battery and charger?
No. The mower is supplied as a tool only. A compatible STIHL AP System battery and charger must be purchased separately unless you already own suitable equipment.
How large a lawn can the RMA 453 PV mow?
STIHL publishes guideline coverage of up to approximately 450m² with one AP 300 S battery and up to 900m² with two AP 300 S batteries. Actual coverage varies according to the lawn, weather, cutting height, drive usage and mowing method.
Is the STIHL RMA 453 PV self-propelled?
Yes. It has variable-speed Vario drive, adjustable between approximately 2.0 and 4.5km/h.
Can the RMA 453 PV mulch grass?
Yes. It can mulch, collect, side discharge or cut and drop. This makes it more versatile than a mower that can only collect clippings.
Will the mower change automatically to the second battery?
Yes. When two compatible AP batteries are installed, sequential discharge allows the mower to switch to the second battery automatically after the first is depleted.
Is the RMA 453 PV suitable for slopes?
The self-propelled drive makes it more suitable for gentle slopes than a comparable push mower. Always follow the operating and safety guidance in the STIHL instruction manual, particularly when working across or near steeper slopes.
Does this mower produce lawn stripes?
The RMA 453 PV is a wheeled mower and does not have a rear roller. It may leave light wheel patterns, but it is not intended to create the defined stripes produced by a dedicated rear-roller lawn mower.
