Greenworks G24PH51 cordless pole hedge trimmer with split shaft (tool only) and 51cm dual action blades

The essentials

If you’ve got small to medium hedges and you want a bit more reach without hauling a bulky machine around, the Greenworks G24PH51 is aimed at exactly that. It’s a cordless pole hedge trimmer designed to help you cut, trim and prune hedges up to about 2m high, with a 51cm blade for the work and a split-shaft design to make transport and storage less of a faff.

One thing to be clear about: this is a “tool only” package. That means it doesn’t include the 24V battery or charger, so whether it’s a good buy depends largely on what you already own in the Greenworks 24V ecosystem.

What stands out in practice

The big day-to-day benefit here is the dual action blade setup. Rather than relying on a single cutting action, both blades move together, which the design is intended to make cuts cleaner and faster. There’s also an anti-jam system, which matters when you’re dealing with denser growth or bits of foliage that like to snag.

Then there’s the head pivot. The trimming head can pivot up to 125°, which is the sort of feature you notice quickly if you regularly need to tidy hedge sides or switch between horizontal and more vertical lines. You can angle the head for more controlled, accurate trimming instead of forcing awkward arm positions.

It also weighs in at 2.8kg, which is fairly important on a pole tool. Over time, lighter tends to feel less punishing when you’re supporting the pole and adjusting your stance.

Key considerations before you buy

This model is built around compatibility with Greenworks 24V batteries, specifically 2Ah or 4Ah units. If you already own one of these batteries from another Greenworks 24V tool, the “tool only” approach can make a lot of sense: you get the trimmer body without paying again for the battery you’ll already have.

If you don’t have a compatible battery, it may feel like it’s missing a big piece of the puzzle. On paper, the performance details provided include a cutting speed of 1500spm and blade cutting up to 18mm, but you’ll still need the right battery to take advantage of it.

Also worth noting: with any pole hedge trimmer, comfort and reach go hand-in-hand with technique. It can be easier to get an even finish when you work in steady passes, but if you’re expecting a full-on “pro sculpting” tool for very thick hedges, the spec you have here may leave you wanting more.

Tech summary

What matters most for different users

It’s a solid pick if you’re maintaining hedges of a similar scale—small to medium gardens where you want a cordless tool that reaches up without turning storage into a problem. The split shaft helps with that “where do I put it?” question, especially if you’ve got limited garage or shed space.

When it makes sense

Buy it if you already have a Greenworks 24V 2Ah or 4Ah battery and you want a hedge trimmer that’s more comfortable to live with: dual action blades for quicker tidying, a pivoting head for accuracy, and a split shaft for easier storage.

A typical use might look like this: you extend the reach, pivot the head to match the hedge line, and trim the top edge first with controlled, overlapping passes. Then you angle for the side growth, using the pivot to keep the cut consistent rather than chasing it with awkward wrist positions.

When you may want to skip it

It might not be the best match if you’re starting from zero on Greenworks 24V batteries. Because it’s tool-only, you’ll need to factor in the extra cost and the space a charger and battery add to your setup.

You may also want to look elsewhere if your hedges are consistently very thick or if you’re after a high-end, maximum-capability cutting setup. This one feels more like a practical, everyday maintenance tool rather than something designed to aggressively power through the toughest situations.

Final verdict

Should you buy it?

Worth considering if

• You have (or plan to use) Greenworks 24V 2Ah or 4Ah batteries already.
• You maintain small to medium hedges and want reach up to around 2m.
• You value a pivoting head for more accurate horizontal and vertical trimming.
• You care about easier storage/transport thanks to the split shaft.

It’s not for you if

• You don’t have a compatible Greenworks 24V battery and don’t want to buy one.
• You need a tool for consistently heavy-duty, very thick hedge cutting beyond what’s implied here.

Is it worth it?

Overall, the Greenworks G24PH51 makes a lot of sense on paper as a cordless, reach-focused hedge trimmer for regular garden tidy-ups—particularly if you’re already in the Greenworks 24V line. The dual action blades and pivoting head are the sort of features that help you get a neater finish without as much struggle. Just don’t overlook the “tool only” setup, if you’re not already equipped with the right 24V battery, it can turn into a more expensive purchase than it first looks.
