If you have extensive hedging to maintain, there is just no substitute for a good gas hedge trimmer. Cordless hedge trimmers are credible and improving, but they still struggle to compete when it comes to absolute power and all-day working capability. And as for dragging a cord around the yard for hundreds of feet? It’s not really a practical solution.
For homeowners with a large garden or professionals who do this kind of work for a living, a gas hedge trimmer is still the tool of choice, but which one? From the motor to the blade to the handle, from budget-friendly to expensive, there are several factors to consider as you shop.
We’ve made some recommendations that offer something for those on a budget and for those looking for high performance. In the buying guide below, we look at all of the important aspects in more detail.
Cycles: With many types of gas-powered garden equipment, you have a choice of four-cycle or two-cycle motors. Four-cycle motors tend to be more durable and slightly quieter, and they run a little cleaner, but they have one major drawback: weight.
For that reason, gas hedge trimmers invariably have a two-cycle motor, and most of the models we looked at were somewhere between 21 and 25 cubic centimeters (cc). That would suggest they all produce similar output, which is true, and the weight only varies by a pound or two. The only real difference between the budget and premium brands is component quality and thus durability.
Emissions: Some manufacturers have put considerable effort into reducing emissions, and the best two-cycle motors are now California Air Resources Board (CARB) and/or Environmental Protection Agency (EPA) compliant. This is becoming increasingly important. There are now 15 states that ban tools that don’t meet the CARB standard.
Horizontal blades: There are two basic configurations for gas hedge trimmers. The most popular is a unit similar in appearance to a chainsaw, but with the blade running horizontally rather than vertically. This gives you a machine that’s well balanced and easy to manage, which is particularly important if you have tall hedges that you have to stand on a ladder or scaffold to cut. It also makes for a more manageable tool for general trimming duties on low hedges and plants.
End blades: The other format looks more like a pole saw or string trimmer, with blades on the end. The pole gives you greater reach, and the head is usually articulated so you can set the blades at the required angle. The drawback with this kind of hedge trimmer is that while you’re more likely to be able to stand on the ground, which is safer, the tool isn’t as easy to control because it can be difficult to see exactly where the blades are cutting. This can lead to an untidy finish. Shorter shafts are available, but for us that seems to negate the benefits of a shaft in the first place.
Inexpensive: The dominance of battery-powered hedge trimmers at this end of the market means the choice is limited. Nevertheless, there are excellent values at around $150. You’ll find a few cordless models in this price range, but one that delivers equivalent power will probably be twice as much.
Mid-range: There’s greater choice in this part of the market, with several high-performance tools between $220 and $330. These provide ample capacity and durability for most homeowners
Expensive: Professionals who want tools with articulation or the larger blade sizes will need to invest between $400 and $500.
Q. Do gas hedge trimmers need much maintenance?
A. Not a huge amount, but it’s important to follow the manufacturer’s instructions carefully to maximize the tool’s working life. Usually this amounts to general cleaning, lubrication, and periodically replacing the air filter and/or spark plug.
Q. How often do I need to sharpen the hedge trimmer blades?
A. It varies from one manufacturer to another, and it depends to some extent on the blade material, but most recommend about every 50 hours. Only sharpen the cutting edges, not the flat areas they cut against. If you’re unsure, find a hardware store or garden outlet that can do the job for you.
If a hedge trimmer isn’t cutting well, it isn’t always that the blades are blunt. It could be a buildup of sappy or resinous material from cutting plants like fir or pine. Clean off the residue with a spirit-based cleaner and a stiff brush.
Q. Are there any special instructions for storing a hedge trimmer out of season?
A. If you’re not going to be using your hedge trimmer for a few months, drain any remaining fuel (and use fresh when you start it again). If you store the tool in a damp shed or garage, moisture will encourage rust. A waterproof canvas case is the best storage. Alternatively, wrap the hedge trimmer in cotton or similar (old towels or T-shirts will do) and then in a large plastic bag.
