Kerlista Articulating Hedge Trimmer Attachment for Stihl Powerheads — OEM 42437405003, Includes Tool Kit

This replacement attachment restores hedge-trimming functionality without replacing your entire power unit. Engineered to match OEM fit and linkage, the assembly is sold with a basic tool set for installation and is compatible with multiple Stihl gas models, giving you a cost-effective way to keep a single engine running many tasks.

Which machines will this blade attachment fit?

The part is manufactured to the OEM specification number 4243 740 5003 and fits a range of Stihl-compatible multi-tool shafts. Confirm fit by comparing your model number to the supported list before purchasing.

• Compatible with KMA130R, KM131R, KM111R and KM130 series engines
• Fits KM13R, KM91R, and KM94RC-E powerheads
• Also supports KM85R, KM56RC-E and KM55RC-E models
• Check your shaft end and mounting bolt pattern for a proper match

How straightforward is installation and what comes in the box?

Installation is designed for a user comfortable with basic hand tools; it mounts to the powerhead in place of the existing accessory. Kerlista includes one attachment and a small tool kit to tighten fasteners and align the linkage, so you can get back to trimming quickly.

• Package includes: one pole saw-style articulating hedge trimmer attachment
• Includes a set of basic tools for assembly and mounting
• Lightweight enough to handle on a telescoping shaft but confirm balance after mounting
• No engine or additional adapters included—sold as the attachment unit

What movement and cutting reach does the articulating head provide?

The articulating joint allows angle adjustment to reach vertical and angled hedges without repositioning the powerhead. While exact degrees depend on your shaft and mounting, the mechanism restores the practical working angles expected from OEM hedge-trimmer heads.

• Articulating head for angled and vertical cutting positions
• Designed to mimic OEM pivot and blade geometry for reliable cuts
• Improves access to high or awkwardly oriented foliage
• Maintain blade sharpness and lubrication for best performance

What should I check for compatibility and safe use?

Before installing, verify your powerhead model and inspect the shaft coupler and mounting points for wear. Follow manufacturer torque settings for fasteners, use appropriate PPE, and test on small branches first to confirm secure fit and balance.

• Match OEM number 4243 740 5003 and your powerhead model list
• Inspect coupler, pins, and fasteners for wear before assembly
• Securely tighten mounting bolts and recheck after first use
• Wear eye, hand, and hearing protection during operation

Who is this for: This Kerlista replacement attachment is aimed at landscapers, property owners, and maintenance professionals who already own a compatible Stihl-style gas powerhead and want a cost-effective OEM-spec hedge-trimming head replacement. It’s ideal for users who prefer repairing and swapping accessories on a single multi-tool engine rather than purchasing separate machines, and for anyone needing restored articulating reach without compromising fit or basic functionality.
