RGA 140 Cordless Brushcutter – AP System

STIHL RGA 140 is a 36-V AP-System brushcutter that swaps the usual high-speed line for a 230 mm reciprocating twin-blade cutter, giving low-spin weed removal near cars, windows and gravel paths; the 1.0 kW brushless motor, 6.4 kg power-head and three-speed control deliver up to 50 min run-time on an AP 300 S while noise stays at 81 dB(A) and vibration at just 2.3 / 2.4 m s².

Designed for professional grounds crews, the RGA 140 uses reciprocating blades rather than a spinning line head, so cut material is not flung outwards; safe working distances shrink to 3 m around property and 5 m near pedestrians, ideal for urban sites with cars and windows. The 36 V brushless EC-motor outputs 1 kW and offers three electronic speed levels on the ergonomic control handle, letting you edge in Eco mode or attack dense growth in Full power. A washable mesh air filter plus IPX4 splash-proof housing protect the electronics for long service life in dust and drizzle.

Key features

  • 230 mm reciprocating blade set – low-spin, low-throw cutting for gravel, asphalt and paved areas.
  • 1 kW brushless motor – maintenance-free, high torque, three speed levels + infinitely variable trigger.
  • AP-slot in power-head – runs all STIHL AP batteries or AR backpacks without a connecting lead.
  • Low noise & vibration – 81 dB(A) sound pressure; 2.3 / 2.4 m/s² HAV for all-day comfort.
  • Smart Connector 2 A ready – mounting point on the housing for fleet management telemetry.

Why choose the RGA 140?

Conventional line trimmers fling gravel and debris—but the RGA 140’s hedge-trimmer-style blades slice instead of spin, so you can de-weed car parks, cemetery paths or solar farms with minimal collateral damage, all while enjoying low noise, low vibration and cordless freedom on the same batteries that power your other STIHL AP tools.

The twin blades move back-and-forth like a hedge trimmer, generating very little rotational energy; debris typically falls within a 3 m radius instead of being flung several metres.

An AP 300 S offers up to 50 minutes per charge and keeps total weight manageable; for maximum endurance use an AR 2000 L backpack, which extends run-time beyond two hours.

Yes—each blade is reversible and can be resharpened several times; rotate or replace when the cutting edge becomes blunt for optimum performance.

The control handle offers three fixed speed levels plus variable trigger control—Eco (~3,000 rpm), Mid (~3,900 rpm) and Full (~4,600 rpm)—to balance torque, noise and battery life.

The reciprocating blade excels at grass and soft weeds; for woody stems above 6 mm switch to a GrassCut or BrushCut metal blade using the Rapid-Click adapter.
