The Ryobi 40V HP Brushless 10-inch pole saw is the best 40 volt pole saw for most homeowners: it pairs a brushless motor with a 10-inch bar and sits in the largest 40V tool family. The Greenworks 40V 8-inch pole saw (PS40B210) is the better light-duty pick if you only trim a few small limbs. Buy the bare tool if you already own 40V batteries, because the battery is half the cost.

A pole saw lets you cut overhead branches from the ground, which beats a ladder and a hand saw for safety. At 40 volts you get enough power for limbs up to about the diameter of your wrist without the weight of gas. This guide sticks to 40V platforms, since batteries from different voltage systems do not interchange. Specs below come from manufacturer listings and published reviews, and runtime depends heavily on the battery you pair with the saw.

Quick Comparison

Best Overall: Ryobi 40V HP Brushless 10-Inch Pole Saw

This is the newest Ryobi pole saw in the retailer and review listings. A June 2026 review from Pro Tool Reviews highlights easy assembly, confident cutting power, a metal trigger guard, good balance and strong value. Brushless motors run cooler, use battery energy more efficiently and need less service than brushed designs. A 10-inch bar handles most backyard pruning.

Trade-off: a 10-inch bar on a long pole is heavier at the tip, which tires your arms when you cut high for a long time.

Best Light-Duty Pick: Greenworks 40V 8-Inch Pole Saw (PS40B210)

Bob Vila’s guide names this model the best light-duty pole saw. It weighs about 9.3 pounds, is about 8 feet 11 inches long and carries an 8-inch bar. A Bob Vila review notes it cuts branches up to roughly 7 inches in diameter, though the bar length makes anything that thick slow. BestReviews cautions that it is not built for frequent use or large jobs.

Trade-off: shorter bar and less sustained power.

Best Combo: Ryobi 40V Pole Saw and Hedge Trimmer

This kit puts a 10-inch bar and a hedge trimmer attachment on the same power head. Bob Vila lists it at around 9 feet long and 14 pounds. It suits yards with both overhead limbs and hedges, saving the cost of a second tool.

Trade-off: weight. At 14 pounds it is tiring for extended overhead work.

Best for Kobalt Owners: Kobalt Gen4 40V 10-Inch Pole Saw

Consumer Reports included a Kobalt Gen4 40-volt 10-inch cordless pole saw in its tests. If you already own Kobalt 40V batteries, it keeps everything on one platform.

Best Budget Older Model: Ryobi 40V 10-Inch (RY40560)

The RY40560 has been around for years and is still sold new, kitted and renewed. It uses a brushed motor, so expect more heat and less efficiency than the brushless HP version. A renewed unit can be a bargain if the battery is included and healthy.

How to Choose a 40 Volt Pole Saw

Bar length and branch size

Match the bar to branch diameter. A rule of thumb is that the bar should be at least two inches longer than the limb. An 8-inch bar is comfortable on branches up to about 4 to 5 inches, while a 10-inch bar handles 6 inches comfortably.

Reach and weight

Reach is the pole length plus your own height, minus a safe margin. A 9-foot pole is about a 13 to 15 foot working reach. Heavier pole saws reduce control at full extension, so choose the lightest that meets your need.

Battery capacity

A 2.0 Ah battery suits trimming a few limbs. A 4.0 Ah or larger pack allows a full cleanup. Because 40V systems differ by brand, buy into the platform whose mower, blower or trimmer you may want later.

Oil and chain care

Most pole saws need bar oil. Keep the reservoir filled and sharpen or replace the chain when it produces dust instead of chips. A dull chain is the leading cause of poor performance and kickback risk.

Worked Example: Cost of Ownership

A homeowner pruning twice a year saves the cost of a hired crew for each session. If a tree service charges a minimum fee for small jobs, the tool plus a battery pays for itself in two or three sessions. Bare-tool purchases cut this further for anyone already on a 40V battery platform.

Safety Notes

• Wear eye protection and a hard hat; falling limbs and sawdust come straight down.
• Stay clear of power lines. Never use a pole saw near energized wires; most poles are not insulated.
• Cut from the underside first on heavy limbs to avoid bark tearing.
• Keep both hands on the pole and stand off to the side of the falling branch.

Which Pole Saw Fits Your Yard

Mistakes That Cause Trouble

The biggest mistake is cutting a heavy limb in one pass from the top. The branch can bind the bar, split the bark down the trunk or swing back toward you. Use the standard three-cut method: a shallow undercut a foot from the trunk, a top cut slightly farther out to drop the weight, then a final cut just outside the branch collar so the wound heals.

Another mistake is skipping bar oil because the saw feels fine. A dry chain heats quickly, stretches and dulls, and the bar can warp. Check the oil level before each session and top it up when you recharge the battery.

Finally, avoid buying only on pole length. A very long pole is useful on a tall tree but becomes clumsy and tip-heavy on lower work. Many owners find a pole that reaches comfortably around 12 feet is more usable than the longest on the shelf. If you regularly prune higher than that, hire an arborist rather than overextending.

Frequently Asked Questions

Is a 40 volt pole saw powerful enough?

For limbs up to about 6 inches in diameter, yes. Larger trunks need a chainsaw or a professional arborist.

How high can a 40V pole saw reach?

Most extend to about 9 or 10 feet, giving a working reach of about 13 to 15 feet when you stand on the ground.

Are Ryobi and Kobalt batteries interchangeable?

No. Each brand uses its own 40V battery design, so check platform compatibility before buying a bare tool.

Do I need to oil a cordless pole saw?

Yes. Bar and chain oil reduces friction and wear. Some models have an auto-oiler; others need manual top-ups.

Brushless or brushed motor?

Brushless is more efficient and durable, so it is worth the modest extra cost if you will use the saw regularly.
