Brushcutter & Trimmer parts

Genuine STIHL Brushcutter & Trimmer Parts

Keep your STIHL trimmer or brushcutter ready for routine property work with genuine OEM replacement parts selected for the correct equipment application. This collection brings together components for fuel-powered STIHL trimmers and brushcutters, from cutting attachments and guards to drive-shaft parts, controls, starting components, and engine-service items. Whether you are replacing a worn component, completing seasonal maintenance, or planning a careful repair, begin with the original STIHL part number whenever it is available.

If the part number is unreadable, verify the complete model, serial information, diagram, component location, stated application, quantity, and included items before ordering.

Shop Trimmer and Brushcutter Parts by System

Finding the repair system first makes part selection more precise. A cutting concern may begin at the trimmer head, line-retaining components, blade hardware, guard, deflector, gearbox, or mounting area. Vibration, unusual noise, reduced output, or loose movement can lead to the drive tube, flexible or solid shaft, coupling, gearhead, clamp, bearing, handle, or fasteners. Starting, fuel, throttle, and running concerns should be traced through their associated air, fuel, intake, ignition, starter, control, and engine assemblies.

• cutting heads, spool components, line hardware, blade hardware, guards, deflectors, covers, and attachment mounting parts;
• gearheads, drive shafts, drive tubes, couplings, housings, bearings, clamps, mounts, retainers, and drive-system hardware;
• throttle triggers, stop switches, lockouts, grips, control handles, cables, wiring, switches, and handlebar components;
• fuel tanks, fuel lines, filters, vents, intake parts, carburetor components, air filters, seals, and gaskets;
• starter housings, ropes, pulleys, rewind springs, ignition components, engine covers, clips, and service hardware.

Cutting Attachment, Guard, and Deflector Components

The cutting end should be serviced as a complete working area rather than as isolated parts. The installed trimmer head or approved blade arrangement, guard, deflector, gearbox, fasteners, and mounting pieces must work together. Replace components that are damaged, cracked, excessively worn, loose, or missing. Do not choose a guard, deflector, head, blade hardware, or mounting piece by appearance alone; the equipment configuration and listed OEM application determine the correct selection.

Drive Tube, Gearhead, and Handle Repairs

Power travels from the power unit through connected drive and control assemblies to the cutting attachment. Inspect the shaft, drive tube, coupling, gearhead, handle, cables, clamps, mounts, housings, and fasteners as one system. A worn coupling, cracked housing, loose tube, damaged handle, missing clamp, cable-routing issue, or worn bearing can affect performance, comfort, and control. OEM references are especially important for these parts because dimensions, connections, mounting positions, and included hardware may differ.

Do not force a shaft, gearhead, cable, coupling, or threaded component into place. If a part does not seat normally, compare the part number and service information before continuing. Persistent vibration, suspected internal gearbox damage, drive-system misalignment, or a repair outside normal maintenance should be evaluated by a qualified outdoor-power-equipment technician.

Fuel, Starting, and Engine-Service Parts

Hard starting, irregular running, fuel leakage, poor acceleration, or throttle problems can have more than one cause. Inspect the relevant assembly before ordering a replacement: fuel tank, line, filter, vent, intake, carburetor, air filter, starter rope, pulley, rewind spring, ignition component, switch, wiring, cable, or engine cover. A product listing helps identify a replacement item, but it does not diagnose a mechanical or safety concern.

After service, confirm that the trigger, lockout, stop switch, cables, covers, guards, and mounting hardware are secure and work normally. Never bypass a safety switch or use the machine with a damaged control, loose cover, missing guard, fuel leak, or unresolved operating problem.

Confirm Compatibility Before Ordering

Use the original OEM part number as the primary compatibility check. When that reference is unavailable, compare your STIHL model, serial number, illustrated diagram, component location, product description, and stated fitment. Product images may show a related version, a complete assembly, or hardware sold separately. Verify whether your repair also needs screws, clips, seals, clamps, washers, gaskets, line components, or mounting hardware.

Part Identification Support

For assistance, provide the model, original part number if known, and a clear photo or component location. State the repair system involved; final compatibility must match the listing’s OEM reference.
