Kerlista Replacementparts Straight Shaft Hedge Trimmer Attachmen Compatible with Capable Head Polesaws Powerheads Lithium Battery PowerHead Replace NO. DWOAS8HT, TPH720,WA0220 Black

What It Is

This is an aftermarket straight shaft hedge trimmer attachment designed for use with compatible pole saw and powerhead systems, specifically those using a universal coupling system found on select lithium battery powerheads (e.g., models replacing DWOAS8HT, TPH720, WA0220). It lets you convert a compatible powerhead into a long-reach hedge trimmer without buying a separate trimmer unit.

Fitment & Compatibility

Critical: This attachment only works with powerheads that have a straight shaft universal coupling system. It is not compatible with curved shaft trimmers or dedicated string trimmers without a removable head.

Before buying, verify:

• Your powerhead model matches one of these: DWOAS8HT, TPH720, WA0220, or any unit explicitly claiming “universal head” compatibility with those numbers.
• The powerhead’s drive shaft is straight (not curved) and has a removable attachment coupling (typically a push-button or twist-lock collar).
• Measurement: The attachment shaft diameter is 0.8 inches (20mm) – measure your powerhead’s output shaft to confirm.
• Not compatible with DeWalt 20V/60V, Ryobi 18V/40V, or other proprietary brand attachments unless they explicitly list these OEM numbers.

Key Things to Know

• Quality vs OEM: This is a budget aftermarket part. The blade steel and plastic housing may be less durable than OEM equivalents. Expect shorter blade life if used on heavy, woody growth.
• Installation: Simple push-and-twist lock (no tools needed), but ensure the locking pin fully engages. A loose attachment can damage the powerhead.
• Gotcha: Some users report the attachment doesn’t lock as tightly as OEM, causing slight wobble at full extension. Test on a low branch before heavy use.
• Weight: The straight shaft adds length and leverage, making it heavier than a dedicated trimmer. Balance may feel off on lightweight powerheads.

Should You Buy It

Buy this if you already own a universal powerhead compatible with the listed OEM numbers, need a budget hedge trimmer attachment for occasional light trimming of soft growth (leaves, small twigs), and are comfortable with slightly looser tolerances than OEM. Avoid if you need a heavy-duty tool for thick, woody hedges or demand perfect fit and finish – an OEM attachment will be more reliable.
