STIHL FH-KM 145° Scrub Cutter KombiTool Attachment

It is particularly useful where a conventional rotary mowing head may be difficult to control, including around paths, kerbs, obstacles, planted areas, slopes and confined spaces. The flexible adjustment mechanism lets you alter the cutter-bar angle to suit the working position, while the head can be placed into a compact position for transport and storage.

Please note: this product is the FH-KM KombiTool attachment only. A compatible STIHL KombiEngine or KombiMotor is required and is sold separately.

Key features of the STIHL FH-KM 145°

• 145° adjustable cutter bar: change the working angle to suit ground-level, sloping and awkward cutting positions.
• 25 cm cutting bar: the compact 10-inch bar provides accurate control in confined spaces.
• Low-spin cutting action: designed for controlled mowing and cutting close to the ground, including narrow and traffic-adjacent areas.
• Flexible adjustment mechanism: position the cutter head for more comfortable and effective working.
• Space-saving transport position: fold the cutter assembly into a more compact position when transporting or storing the attachment.
• STIHL KombiSystem connection: attach and remove the tool through the standard KombiSystem coupling.
• One power unit, multiple tools: expand an existing KombiSystem without purchasing another complete machine.

What is the FH-KM scrub cutter designed to cut?

The FH-KM is intended for controlled cutting of grass, weeds, scrub and low-growing vegetation. Typical applications include:

• Cutting close to the soil or ground surface
• Clearing vegetation around kerbs, paths and obstacles
• Maintaining grass and weeds in narrow spaces
• Working on slopes and uneven ground
• Cutting beneath or between established planting
• Low-spin mowing in areas where control is important
• Garden, estate, commercial and landscaping maintenance

For routine grass edging with nylon line, consider the STIHL FS-KM strimmer attachment. For trimming the faces and tops of established hedges, the STIHL HL-KM 145° long-reach hedge trimmer is normally the more appropriate attachment.

FH-KM versus other STIHL KombiTool attachments

FH-KM versus HL-KM

The FH-KM has a compact 25 cm cutter bar and is designed primarily for ground-level scrub, grass and low-growing vegetation. The HL-KM is a longer-reach hedge-trimmer attachment intended for trimming hedge faces, sides and tops.

FH-KM versus FS-KM

The FH-KM uses a cutter bar for controlled, low-spin vegetation cutting. The FS-KM uses a conventional mowing head and is better suited to routine grass trimming, edging and clearing around obstacles.

FH-KM versus HT-KM

The FH-KM cuts grass, weeds and scrub close to the ground. The STIHL HT-KM pole pruner is designed for pruning elevated branches and woody growth.

Frequently asked questions

What is the STIHL FH-KM 145° used for?

It is used for close-to-ground cutting and low-spin mowing of grass, weeds, scrub and low-growing vegetation. Its compact cutter bar is particularly useful in narrow spaces and around obstacles.

Is the FH-KM a hedge-trimmer attachment?

How long is the FH-KM cutter bar?

The cutter bar is 25 cm, equivalent to approximately 10 inches.

How much does the STIHL FH-KM weigh?

The attachment weighs 2.1 kg. The complete operating weight will depend on the KombiEngine or KombiMotor being used.

Can the FH-KM be adjusted for transport?

Yes. The flexible cutter-bar mechanism can be placed into a compact, space-saving position for transport and storage.

Will the FH-KM fit my STIHL KombiEngine?

STIHL describes the FH-KM 145° as suitable for its KombiEngines. Check the instructions for your individual power unit or contact Masseys when purchasing an older or discontinued model.

Safety information

Always use suitable personal protective equipment and read the current STIHL operating instructions before fitting or using this attachment. Low-spin operation does not remove the risk posed by cut material, moving blades or nearby people, vehicles and property.
