When it comes to keeping hedges trimmed and tidy, having the right tools for the job is essential. For many homeowners with larger properties or long hedgerows, gas powered hedge trimmers are an indispensable tool. But are they really worth the higher price tag compared to electric or manual models? There are pros and cons to consider.

The power and performance of gas hedge trimmers
Gas hedge trimmers have some key advantages that make them a worthwhile investment for certain users:
More power for thicker branches
The main benefit of gas hedge trimmers is the power they provide. Gas engines have much higher torque than electric motors, which allows the cutting blades to slice through thick, woody stems with ease. This extra power makes quick work of large hedges and shrubs. Electric and manual models often struggle or bind up when faced with thicker branches.
Extended run times
Another advantage stemming from the gas engine is significantly longer run times per tank of fuel compared to a single charge of an electric battery. Gas trimmers can typically run for 2-3 hours on a full tank, while electric models may only last 30-60 minutes before needing a recharge. This allows gas trimmers to tackle very large properties in one session.
Consistent power delivery
Unlike electric batteries which slowly lose power as they are drained, gas engines deliver consistent cutting power until the fuel tank is empty. There is no degradation in performance while operating. They maintain their high torque and speed from the first cut to the last.
Less restricted range
Cordless electric trimmers must stay close to the outlet where they are charged. Corded electric models have limited range from the outlet based on the length of extension cord. Gas trimmers have no cords restricting their range, allowing access to large or remote properties.
Downsides of gas hedge trimmers
While gas trimmers have some clear advantages, there are also some downsides to consider:
Higher cost
The most obvious downside is the higher initial purchase price of gas hedge trimmers compared to electric or manual options. Gas-powered equipment costs more because of the complex engine technology involved. The average gas trimmer will be around $300, while basic electric models start around $100.
Heavier weight
The gas engine and fuel tank makes these tools much heavier than electric or manual trimmers. This can limit maneuverability and increase fatigue during extended use. The average weight of a gas trimmer is 10-15 lbs compared to 5-8 lbs for cordless electric.
Maintenance requirements
Gas engines require much more frequent maintenance than electric motors. The spark plugs, air filters, and carburetors need servicing to keep them running well. This involves more time and cost compared to electric models. Proper off-season storage is also required to avoid issues.
Emissions and noise
Exhaust fumes and noise from gas engines can also be unpleasant during operation. Electric options are cleaner and quieter for the user and environment. But gas engine technology is improving these factors over time.
Key factors to consider
When deciding if gas hedge trimmers are worth the investment, there are a few key factors to consider:
How much hedge area needs maintenance?
For very small suburban yards, manual or electric trimmers will usually suffice. But anyone maintaining long boundary hedges or ornate garden hedges should consider gas for the extra power and range.
Thickness of branches?
Thicker stems up to 3/4 inch diameter can only be cut efficiently with gas power. Manual and electric models often jam or bind on woody stems.
Access to fuel and maintenance?
Convenient access to gasoline for refueling needs consideration. Performing maintenance like oil changes and air filter cleaning also requires some mechanical know-how.
Noise restrictions?
In neighborhoods with noise regulations, the louder gas engines may be problematic. Electric models are much quieter.
Operator strength and experience?
The heavier weight and powerful torque of gas trimmers makes them difficult for some users to control safely. Inexperienced operators should start with lighter electric models first.
Here is a comparison table of gas, electric and manual hedge trimmers:
| Trimmer Type | Gas | Electric | Manual |
|---|---|---|---|
| Power | Very high | Moderate | Low |
| Max cutting thickness | 3/4 inches | 1/2 inches | 1/4 inches |
| Run time | 2-3 hours | 30-60 mins | Continuous |
| Range | Unlimited | 50-100 feet | Unlimited |
| Weight | 10-15 lbs | 5-8 lbs | 2-4 lbs |
| Noise level | High | Low | Very low |
| Emissions | High | None | None |
| Initial cost | $200-$500 | $100-$250 | $50-$150 |
Maintenance tips for gas hedge trimmers
To keep gas hedge trimmers running smoothly for years, follow these key maintenance practices:
Regular oil changes
– Change oil after first 5-10 hours of use, then every 50 hours or per manual
– Use quality 4-stroke engine oil of proper viscosity
– Check oil level before each use
Clean/replace air filter
– Remove and clean foam filter monthly with soapy water
– Replace paper filter elements annually or as needed
– Check for dirt buildup impeding air flow
Inspect spark plug
– Remove and inspect spark plug every 100 hours of runtime
– Replace plug each season or as electrode wears down
– Ensure plug gap matches engine specifications
Clear debris buildup
– Keep engine cooling fins and air intakes clear of leaves/debris
– Blow out dust from crevices using compressed air
– Ensure throttle linkage moves freely
Proper storage
– Drain fuel or add stabilizer before long-term storage to avoid gumming
– Wipe equipment down and store out of weather in clean location
– Remove battery and store it separately if equipped
Following these maintenance practices will maximize performance and extend the operating life of gas hedge trimmers. Taking proper care of the engine is essential.
Safety tips for gas hedge trimmer operation
While powerful and efficient, gas hedge trimmers also require safe operating practices to prevent injuries and accidents:
Wear protective gear
Always wear sturdy boots, long pants, gloves, and eye/ear protection when running a gas trimmer. Thick shrubs can hide hazards.
Keep firm two-handed grip
With the throttle lock engaged, use both hands to control the trimmer to counteract torque. Don’t operate with one hand.
Mind blade direction
Be extremely cautious of the direction the cutting blades are rotating to avoid contact. All bystanders should remain at a safe distance.
Support trimmer during startup
The startup sequence on gas trimmers engages the blade immediately, so be sure the head is supported off the ground and clear of obstructions.
Avoid hot surfaces
The muffler and surrounding areas get extremely hot during and after operation. Allow surfaces to fully cool before handling the trimmer.
Refuel carefully
Always shut down the engine before refueling, and avoid spilling gasoline on hot engine surfaces. Move 30 feet away before restarting after refueling.
Inspect area first
Do a thorough walkthrough to remove any debris, rocks or sticks from the cutting path that could be thrown or damage the blades.
Following basic safety practices will prevent many common gas trimmer accidents. Pay full attention when operating.

Conclusion
For homeowners with extensive hedges to maintain on a regular basis, gas powered hedge trimmers are usually a smart investment. The extra power and extended run times allow quick work of large properties. But the higher upfront cost, maintenance, emissions, and safety considerations should not be underestimated.
Electric and manual options offer a simpler, more affordable choice for smaller suburban lots. But they lack the strength and range to tackle thicker branches and expansive hedge lines efficiently.
Analyze your specific hedge maintenance needs, budget, and capability to handle a gas powered tool safely. For the right user, a professional-grade gas trimmer can be an indispensable time and effort saving tool that pays for itself over time. Proper use and care will ensure years of reliable service trimming your hedges to perfection.
