Unique Features

Now let’s check what unique features Greenworks installed in the 20672.

G-MAX No-Fade Battery

The 20672 comes with a 40V, 2-Ah Li-Ion battery pack. Eventually, Li-Ion batteries suffer from memory effect or a gradual loss of maximum storage capacity due to improper charging cycles.

However, Greenworks’ G-MAX technology solves this problem.

The 20672’s G-MAX No-Fade battery pack will never experience memory loss for up to two years. For 48 months, users will get the full effects of a 40V battery, including longer-lasting runtimes and maximum output power.

Tool-Free Tensioning

Near the bar is a tensioning screw that adjusts the tightness the chain to keep it tightly wound around the bar’s edge.

A dial found on the side of the tool’s head also lets you tighten or completely loosen the chain for easy sharpening or replacing.

 

Performance, Design, and Safety

Here, we’ll talk about the 20672’s overall performance, design, and safety features.

Performance

The 20672 performs as admirably as you could ever hope. The eight-inch bar does quick work out of sawing through thick branches, and the extendable three-piece pole can help in reaching the tops of trees without stepladders.

Since it’s a cordless model, you won’t need to worry about tripping over extension cords or relying on portable generators.

However, we recommend investing in a second and maybe third battery pack to reduce downtime by a significant amount.

Design

The 20672’s design is almost perfect in every way. The only major complaint customers have is that the pole comes in three pieces. The twist-lock mechanism is easy to use, but it does slow work down by quite a bit.

The twist-lock system leaves plenty of room for error. Users will need to make sure that both twist-lock components are safely secured when extending the shaft to its max height.

Some buyers have experienced the top-most shaft portion sliding downward slightly while working.

Safety

The only safety feature installed into the 20672 is the lock switch that prevents accidental startups.

By pressing and holding the safety lock switch, only then can you pull the throttle that automatically ramps the motor and sends the cutting chain spinning at its highest speed.

Overall, the 20672 is safe to use, provided users follow the safety guidelines states in the operator’s manual.

 

Ease of Maintenance, Repairs & Warranty

Here, we’ll quickly go over the maintenance procedures and warranty coverage of the 20672.

Ease of Maintenance and Repairs

Maintaining cordless pole chainsaws doesn’t require much thought, and the same principle applies to the 20672.

First, before running the tool, make sure that the chain is tightened around the bar’s edge to ensure nice, clean cuts with each sweep of the pole chainsaw.

Other maintenance includes checking the translucent oil tank for sufficient amounts of lubricant.

The auto-oiling system should ensure that the chain moves smoothly along the bar to keep the motor from overworking and potentially burning out.

Warranty

Greenworks protects its customers by providing a limited four-year warranty for the 20672.

The warranty covers the fixing and replacement costs of defective parts caused by manufacturing errors. Greenworks also provides a one-year warranty for the 40v, 2-Ah battery pack.

If you have any questions or concerns, you can contact their customer help hotline at 1-888-90WORKS between 9 AM and 5 PM EST or visit the company website at www.greenworkstools.com.

Price of Greenworks 20672

The 20672 is a mid-range pole saw that performs exceptionally well at simple pruning and shaping jobs.

Based on its price tag, it’s not exactly a budget-friendly pole saw, but some costlier models aren’t at the same level as this pole saw model.

If you’re looking for an affordable model that is objectively better than this one, we recommend taking a look at the Sun Joe 6.5-amp SWJ800E.

 

Who Should Buy Greenworks 20672?

The Greenworks 20672 is one of the better pole saws we’ve seen. Its high-reaching pole saw—up to 15 feet—is lightweight, durable, and easy to maneuver.

However, there isn’t anything too spectacular about his pole saw apart from the G-MAX battery pack. It certainly does the trick, but we can’t find anything specific about it that makes it stand from the vast sea of pole saws.

Nonetheless, the 20672 is an excellent tool for pruning and trimming branches and stems. Anyone from hobbyist lawn carers to pro tree doctors would enjoy using this cordless pole saw.

Why We Like It

Overall, the 20672 is one of the best cordless pole saws out there. Its powerful motor and far cutting range make it easier to remove high-up branches to improve your lawn’s appearance.

The fact that it’s cordless means unrestricted movement and better cutting accuracy.
