Drive Shaft for Petrol Brushcutter GEKO G81069E — Square Shaft (100 mm)

Replacement drive shaft designed for GEKO petrol brushcutters with a square cross-section and a 100 mm shaft length. This component transfers rotational torque from the engine to the cutting head and is intended for repair or maintenance of compatible gasoline grass trimmers and brushcutters. The shaft is produced to match the mechanical fit and functional requirements of the brushcutter drive system described in the product title.

Advantages

The square-section design ensures positive torque transmission and reduces slippage between coupling elements. A standardized 100 mm length provides compatibility with units built to the same dimensional specification, allowing straightforward replacement without modifications. Made for use in petrol brushcutters, the shaft is a focused spare part intended to restore mechanical connection between engine output and cutting attachment.

Suitable for

• Repair of GEKO petrol brushcutters with matching square shaft interface
• Replacement of worn or damaged drive shafts in compatible gasoline grass trimmers
• Maintenance operations where restoring reliable torque transmission is required

Key specifications

• Shaft cross-section: square
• Nominal shaft length: 100 mm
• Function: transmit rotational torque from engine to cutting head
• Application: petrol brushcutters / gasoline grass trimmers

How to use

Before installation, ensure the brushcutter is switched off, cooled down and spark plug wire disconnected for safety. Remove the cutting head and any housings or couplings that obstruct access to the drive shaft according to the machine’s service instructions. Extract the damaged shaft and fit the replacement by aligning the square cross-section with the corresponding mating parts; secure fasteners and couplings to the original torque settings where specified. Reassemble the cutting head and guards, then perform a functional check at low engine speed to verify correct engagement and absence of unusual vibration or play.

Usage recommendations

Use only with models and assemblies that match the square shaft geometry and 100 mm length specification. Inspect couplings, bearings and retaining hardware during replacement and replace any worn components to ensure safe and reliable operation.
