STIHL FSA 120 Bike Handle Brushcutter (FA08 200 0055)

STIHL FSA 120 Bike Handle Brushcutter (FA08 200 0055) is a cordless option for mowing long grass across gardens, properties and larger maintained areas. Its adjustable bike handle supports a sweeping mowing action, while the efficient EC motor and two speed settings let you match cutting speed to the task.

Skin Only and Battery Options

Supplied with AutoCut 27-2 mowing head and shoulder strap. Battery and charger are not included. Cordless system: STIHL ALLPRO / AP.

• STIHL ALLPRO AP 300.0 P battery (EA13 400 6523): newer ALLPRO option, sold separately.
• STIHL AP 300 S battery (4850 400 6575): recommended legacy AP option, available only while remaining stock lasts.

AP 200 and AP 300 S are remaining-stock lines and will not be available once sold out. AP 500 S is no longer sold by Betontools; its runtime information below is retained for existing owners. Legacy AP and newer ALLPRO are distinct battery models. Do not apply legacy runtime figures to ALLPRO batteries. A compatible charger is required and sold separately.

Optional Grass Blades

The following grass blades are suitable options for the FSA 120 when fitted with the complete approved guard, mounting hardware and harness combination. All are sold separately and are not included with this AutoCut-equipped listing.

• GrassCut 230-2, 230mm, 25.4mm bore (4001 713 3805).
• GrassCut 260-2, 260mm, 25.4mm bore (4001 713 3812).
• GrassCut 230-4, 230mm, 25.4mm bore (4001 713 3801).

Use only the complete cutting-tool combination approved in your exact FSA 120 instruction manual, including the correct metal-tool guard, mounting hardware and required harness. Do not assume the supplied line-head setup is ready for metal blades. Remove the battery before changing attachments and keep both hands on the handles during use. Brush knives, circular saw blades and shredder blades are not recommended here.

Blade Fitting Hardware

The STIHL blade fitting kit 4001 007 4400 (40010074400) is suitable for FSA 120 and sold separately. It contains a thrust washer, rider plate and M10 x 1.0 left-hand collar nut. Confirm the mounting parts required for your exact machine and selected blade before ordering. This is mounting hardware, not a universal adaptor or complete conversion kit, and does not include a guard or harness.
