KM 90 R - Powerful 0.95kW KombiEngine with 4-MIX engine and loop handle

Standard features

STIHL 4-MIX engine:

You can always rely on STIHL to keep setting new benchmarks this time with 4-stroke mixed lubrication technology. The STIHL 4-MIX engine, which runs on a fuel-oil mix just like a 2-stroke, offers the benefits without the compromises of 4-stroke power. STIHL 4-MIX engine technology provides fast acceleration, more power, added torque, lower noise, reduced emissions and increased fuel efficiency to complete jobs quickly, quietly and more easily.

Standard features

Loop handle (R):

The loop handled grass trimmers and brushcutters are ideal for working in areas where space is limited, e.g. thinning between bushes and shrubs.

Standard features

Quick-release coupling:

The quick-release coupling allows the KombiSystem to be quickly dismantled into two parts for easy transport and storage – and then re-assembled quickly without tools.

Standard features

Split shaft:

With split shaft and special no-tools quick-release coupling the KombiSystem is highly versatile, easily transported and easy to store.

Standard features

Multi-function control handle:

This houses all the engine controls. Easy, comfortable thumb-operated control means the operator's hand never leaves the handle.

Standard features

Decompression system:

The decompression valve allows some of the compression pressure in the cylinder to escape, so less force on the starter rope is needed.

Standard features

Shoulder strap / carrying system:

Using a STIHL shoulder strap or carrying harness with soft padding makes work more comfortable, particularly during lengthy jobs.

Standard features

Electronic ignition module:

This ensures reliable starting and trouble-free running. The ignition system is fully encapsulated and thus proof against damp and dirt.

Standard features

Anti-vibration system:

Intense vibration at the handles of power tools can lead to longer-term effects of blood vessels in the hands and arms. STIHL have therefore developed an effective anti-vibration system where by the oscillations from the machines engine are dampened by rubber buffers. This significantly reduces vibrations at the handles allowing for more comfortable and safer operation.

Powerful robust KombiEngine for demanding and frequent applications. With the patented STIHL 4-MIX engine providing fast acceleration, more power, added torque, lower noise and increased fuel efficiency when compared to a 2-stroke engine. With loop handle for difficult terrain and confined conditions. Quick release coupling for easy dismantling and changing of tools. Suitable for all KombiTools.
