Greenworks 40V 20 in Replacement Hedge Power Head (Tool Only) — 3-Position Pivot, 5/8-inch Cut

Swap a worn cutter or change your trimmer’s reach with the Greenworks 40V 20" replacement hedge power head — a cordless pole trimmer attachment (tool only) designed to restore trimming performance.

This replacement power head fits Greenworks 40V pole hedge trimmer models PH40B210 and PSPH40B210, giving you a quick way to revive a favorite tool without buying a whole new unit. It’s engineered to deliver easy, controlled cuts across most hedges and shrubs thanks to a 5/8-inch cutting capacity and a 3-position pivoting head that lets you work at different angles. Because this listing is for the attachment only, the control handle and battery-equipped tool are not included — perfect for users who already own the matching Greenworks drive unit.

Will this power head fit my Greenworks 40V pole trimmer?

If you have a Greenworks PH40B210 or PSPH40B210 pole hedge trimmer, this replacement head is made to match the connection and mounting points of those models. It allows you to reuse your existing shaft, motor, and battery so you keep familiar balance and controls while renewing cutter performance.

• Compatible models: PH40B210 and PSPH40B210
• Mounting matches original Greenworks attachment interface
• Designed to reuse your tool’s handle, motor and battery pack

How does the 3-position pivoting head improve trimming?

The head pivots to three different positions so you can adjust blade angle for vertical, horizontal, or angled cuts without twisting your wrists or changing your stance. That flexibility makes it easier to reach tops of hedges, sides, and awkward angles while maintaining a consistent cutting path for neater results.

• Three-lock positions for versatile blade orientation
• Reduces strain by letting you change angles instead of posture
• Helps achieve uniform trims across varied hedge shapes

What size branches can this head handle and what tasks is it best for?

The cutter accommodates branches up to 5/8 inch diameter, handling the majority of residential hedge and shrub trimming needs. It’s optimized for shaping, thinning, and routine maintenance rather than heavy-duty limb removal, making it ideal for seasonal shaping and frequent tidying.

• 5/8" cutting capacity for most bushes and hedges
• Best for shaping, trimming, and light pruning tasks
• Not intended as a substitute for chainsaws or large branch pruners

What should I know about installation and what’s included?

Installation is straightforward when replacing the original attachment on a compatible Greenworks pole trimmer: line up the mounting points and secure according to the manufacturer’s instructions. Note that this product is a replacement attachment only — the control handle, shaft, and battery/motor assembly must be supplied by your existing compatible tool.

• Replacement attachment only; control handle and tool not included
• Follow Greenworks instructions for secure mounting and safety checks
• Quick swap process if you already own a compatible Greenworks drive unit

Who is this for? This replacement power head is for Greenworks owners who need a like-for-like cutter refresh without replacing the entire pole trimmer. It’s especially useful for homeowners and property caretakers who perform regular hedge maintenance, want a fast repair option after wear or damage, or who keep multiple attachments on hand to expand the utility of one cordless drive system.
