If your hedges are taller than you can comfortably reach from the ground, you have two choices: haul out a ladder and trim with a handheld hedge trimmer (dangerous), or use a long reach hedge trimmer designed for the job (safe and dramatically faster).
Ladder-plus-hedge-trimmer accidents send thousands of homeowners to emergency rooms every year. A dedicated pole hedge trimmer — sometimes called a long reach hedge trimmer or pole hedger — puts the cutting blade at the end of a 6–9 foot extension pole, letting you trim tall hedges while both feet stay planted on the ground.
This guide covers when a long reach trimmer is the right call vs. a handheld model, what specs actually matter, safety considerations that aren't optional, and the Greenworks 80V pole hedge trimmer built for serious residential hedge work.
When You Need a Long Reach Hedge Trimmer
Consider a pole hedger if any of these apply:
- Your hedges are over 6 feet tall. Above that, a handheld requires a ladder — and hedge trimmers on ladders are a top cause of home injuries.
- You have wide hedges you can't reach across. A long reach trimmer lets you cut the middle of a 5-foot-wide hedge from either side without walking on the hedge itself.
- You trim tall privacy cedars. Standard Canadian privacy cedars often grow to 10+ feet — impossible to trim safely without a pole hedger.
- You maintain formal or shaped hedges. The pole gives you consistent geometry from top to bottom, which matters for hedges shaped into rectangles, spheres, or archways.
- You're getting older or have joint issues. Ladder work compounds risk. Ground-based trimming is dramatically safer.
You probably don't need a pole hedger if your hedges are all under 5 feet tall — a handheld with a rotating handle handles that job better because it's lighter and more maneuverable at ground-level heights.
Handheld vs Long Reach — When to Use Which
| Handheld Hedge Trimmer | Long Reach / Pole Hedge Trimmer | |
|---|---|---|
| Best for | Hedges under 5 feet, detail work | Tall hedges (5'+), wide hedges, top-down maintenance |
| Overhead reach | Arm's length only | Up to 12–14 feet |
| Weight feel | ~8 lbs, in your hands | ~9–10 lbs, balanced on the pole |
| Ladder needed? | Yes, for tall hedges | No — that's the whole point |
| Detail work | Excellent | Difficult at ground level |
| Vertical cuts | Standard | Requires blade angle adjustment |
Many homeowners with mixed hedge conditions end up owning both. The 80V battery platform makes this cost-effective — the same battery runs both handheld and pole models.
What "Best" Means for a Long Reach Hedge Trimmer
Five specs separate a great pole hedger from a mediocre one:
- Total reach — how high you can trim while standing on the ground
- Blade length — how much hedge you cut per pass
- Cut capacity — the maximum branch diameter the blade severs
- Voltage and motor type — determines torque under sustained load
- Balance and weight distribution — critical because the whole tool is held at extended arm's length
Total Reach: The #1 Spec
Total reach combines the extension pole length with the user's height and arm reach. Most quality pole hedgers offer reach in the 11–14 foot range.
| Reach Range | Best For |
|---|---|
| Under 10 feet | Medium-height hedges (5'–7') |
| 10–12 feet | Tall privacy hedges (7'–9') |
| 12+ feet | Very tall hedges (10'+) and top-down maintenance |
For most Canadian homeowners with privacy cedars, a 12-foot total reach handles nearly everything. Beyond that gets unwieldy — a 15+ foot tool becomes hard to control and dangerous.
Important safety note: never extend a pole hedger with auxiliary poles. Manufacturers specifically advise against this because the leverage at the cutting head increases exponentially with reach, and the balance becomes unmanageable. If your hedges are taller than any commercially available pole hedger can reach, hire an arborist.
Blade Length and Cut Capacity
At the end of the pole, you have essentially a hedge trimmer. Same specs matter:
- Blade length: 18"–20" is the residential sweet spot for pole models. Longer blades are hard to control at the end of a pole. Shorter blades slow you down.
- Cut capacity: 1/2" cut capacity minimum for residential use. 3/4" is premium — the range that handles overgrown new growth and thick stems without bogging.
The Greenworks 80V pole hedger uses a 20" blade with 3/4" cut capacity — the residential premium tier.
Voltage: Why 80V Matters More at the End of a Pole
Pole hedge trimmers face a mechanical disadvantage that handheld hedge trimmers don't: the motor is at the end of a long pole, so any power loss between motor and cutting blades is amplified. This makes voltage and motor efficiency more important for pole models than for handhelds.
- 20V to 40V: Underpowered for the pole configuration. Will bog on anything but light new growth.
- 60V: Adequate for light residential pole trimming. May struggle on overgrown hedges.
- 80V: Gas-equivalent. Cuts through thick stems and semi-hardwood branches even at extended reach.
And always look for brushless motors. Pole hedgers run under continuous load with the added weight of an extended pole. Brushless motors run cooler under sustained load, deliver more torque per watt, and last dramatically longer than brushed motors — especially critical when the motor is mounted at the end of a pole where cooling is less efficient.
Balance and Weight Distribution
Total weight matters less than where the weight sits. A perfectly balanced 10-lb pole hedger feels lighter than a poorly balanced 8-lb model. Look for:
- Motor location: Motor at the cutting head balances the tool forward. Motor at the base (near the trigger) balances rearward. Front-mounted motors feel more nose-heavy but give better cutting control; rear-mounted feel lighter but require more wrist strength for precision.
- Aluminum or fiberglass pole: Both are lightweight. Aluminum is more rigid; fiberglass has slightly more flex (which absorbs vibration).
- Auxiliary handle position: Adjustable auxiliary handles let you find the balance point that works for your height and reach.
The Greenworks 80V pole hedger weighs 9.46 lbs — light for a 20"-bladed pole model. The design keeps weight distributed so it's manageable during extended sessions.
The Best 80V Long Reach Hedge Trimmer from Greenworks
For homeowners with tall hedges, wide privacy screens, or professional-grade landscaping needs, the Greenworks 80V 20" Pole Hedge Trimmer (2x 2.0Ah Batteries + Charger) hits every spec that matters:
| Spec | Greenworks 80V 20" Pole Hedge Trimmer |
|---|---|
| Voltage | 80V brushless |
| Blade length | 20" |
| Cut capacity | 3/4" |
| Reciprocating speed | 3,200 SPM (±10%) |
| Extension pole | 9 feet |
| Batteries included | 2 × 2.0Ah 80V lithium-ion (144 Wh each) |
| Rapid charger included | 30-minute charge time |
| Weight | 9.46 lbs |
| Warranty | 4-year tool + battery |
Features worth highlighting for pole hedger use specifically:
9-foot extension pole with 20" blade. Combined with the average person's arm reach, this gives you roughly 12–13 feet of total working reach — enough for privacy cedars up to about 11 feet tall.
3/4" cut capacity — premium residential tier. Handles thick new growth, overgrown stems on neglected hedges, and semi-hardwood branches without bogging. Critical for pole use because you can't apply as much force with a pole tool as with a handheld — you need the blade to do the work.
Two 2.0Ah batteries included. Real-world runtime on pole hedgers is usually 30–45 minutes per 2.0Ah battery. With two included, you can trim continuously for 60–90 minutes — enough for most residential hedge work in a single session.
30-minute rapid charger. If you finish one battery mid-session, the second is ready in 30 minutes — before you're done with the first. Effective continuous operation.
3,200 SPM blade speed. Fast enough for clean cuts on semi-hardwood; not so fast that vibration becomes fatiguing at the end of a pole.
Cross-compatibility with 75+ Greenworks 80V tools. The 2.0Ah batteries in the kit work in all Greenworks 80V tools — mowers, trimmers, blowers, chainsaws. If you already own 80V tools, you can rotate batteries between them.
4-year warranty on both tool and batteries. Battery warranty specifically matters — the batteries are the highest-wear components.
Pole Hedger Technique — Getting Clean Cuts from Below
Pole hedging is different from handheld work. Three technique tips:
- Cut with the blade parallel to the hedge face. Tilting the blade creates uneven cuts and gets it stuck. Adjust the blade angle at the handle before starting each section.
- Work in strips, not sections. Trim a horizontal strip along the entire hedge length before moving to the next strip below or above. Trying to finish one full-height section before moving on creates visible seams.
- Trim from top to bottom. Falling debris covers areas you haven't cut yet. If you start at the top, you clear falling debris as you work downward.
Also: keep the bottom of the hedge wider than the top. This is counter-intuitive but critical — it lets sunlight reach the lower branches. Straight-up trimming eventually shades the bottom and lower branches die out.
Pole Hedger Safety — Non-Negotiable
Pole hedgers eliminate the ladder risk but introduce new safety concerns:
- Never work under overhead power lines. The metal pole conducts electricity. Even brief contact with a live line can be fatal.
- Keep both hands on the tool at all times. One on the pole shaft, one on the rear handle. Never one-handed.
- Watch for falling debris. Clippings, sap, insects, and branches all come down from what you're cutting. Wear safety glasses and a hat.
- Don't overreach. Keep proper footing. If you can't cut a section from a stable stance, move yourself — never lean into the tool.
- Keep bystanders 30+ feet away. Falling debris and blade fragments (rare but possible) can travel further than expected.
FAQ
How high can a long reach hedge trimmer actually reach?
Combined with the operator's height and arm extension, most quality 9-foot pole hedgers reach 12–13 feet total. The Greenworks 80V falls in this range. Above 13 feet, professional arborists are the right call.
Can I use a pole hedger as a regular handheld?
No. Pole hedge trimmers are not designed to be dismantled into handheld models — the mounting, weight distribution, and controls are optimized for pole use. Buy a separate handheld hedge trimmer for lower work.
How long does the battery last per charge?
Roughly 30–45 minutes on a 2.0Ah battery under typical residential load. Heavier cutting (overgrown hedges) shortens this to 20–30 minutes. The Greenworks kit includes two batteries — enough for most residential sessions.
Are pole hedgers safe on ladders?
No — never use any hedge trimmer on a ladder. The whole point of a pole hedger is to eliminate ladder use. If your hedges are taller than the pole hedger reaches from the ground, hire a professional.
Can I trim hedges when they're wet from rain?
Not recommended. Wet hedges are slippery underfoot, and battery tools are splash-resistant but not waterproof. Wait until the hedges dry.
How often should I trim my hedges?
Light monthly trims during the growing season (May–September) keep hedges manageable. Heavy annual trims fight overgrowth in one difficult session. Frequent light trims produce better-looking hedges with less effort.
