RMA 253.3 Cordless Lawn Mower (AK Power Unit) by STIHL

51 cm cutting width for medium-to-large -sized lawns

STIHL RMA 253.3: Powerful 51cm Cordless Push Mower for Medium Lawns

The STIHL RMA 253.3 is a high-capacity cordless push mower designed for homeowners who prioritize maneuverability and versatility. With its substantial 51cm (20") cutting width, it bridges the gap between compact domestic mowers and larger professional units. Part of the interchangeable AK System, it provides a quiet, exhaust-free mowing experience with enough power to maintain up to 275m² on a single charge.

Advanced 4-in-1 Mowing System

  • Full Flexibility: Adapt to any season or grass condition with four discharge options: traditional collection, rear discharge (cut and drop), side discharge, or nutrient-rich mulching.
  • Standard Accessories: Unlike many entry-level models, the mulch plug and side discharge flap are included as standard, giving you professional versatility right out of the box.
  • 52-Litre Grass Box: Features an optimized airflow design for maximum filling and an enhanced fill-level indicator to eliminate guesswork during your mowing session.

Intelligent Design & Efficiency

  • Push-Propelled Control: The lightweight construction and push-drive allow you to set your own pace and navigate precisely around flower beds, trees, and delicate borders.
  • Dual Battery Slots: Includes an active battery slot and a secondary transport compartment. This allows you to carry a spare AK battery on board for a near-instant switchover, effectively doubling your mowing range.
  • Precision Height Adjustment: A single-point, spring-assisted lever allows you to select from several cutting height increments ranging from 20mm to 100mm—perfect for the first cut of spring.

Premium Build & Storage

  • Comfort Mono-Handlebar: STIHL’s signature mono-handle design provides unobstructed access to the grass box for effortless removal. It is also height-adjustable, lockable, and foldable for space-saving vertical storage.
  • Smooth-Running Wheels: Equipped with double ball bearing-mounted wheels featuring a traction-optimized profile, ensuring the mower glides across the turf while remaining gentle on your lawn.
  • AK System Compatibility: Use the same 36V lithium-ion battery to power your STIHL blowers, hedge trimmers, and chainsaws.

Please Note: This is a Power Unit (Tool Only). Battery and charger are sold separately. For optimal performance on lawns up to 275m², we recommend the AK 30 S battery.
