The Buying Guide
There are several factors to always keep in mind when shopping for a cycle string trimmer. Once you have these figured out, it will be super-easy to make an informed decision.
# Engine Capacity
Big engines tend to have more cutting power. But how big is big? Well, any engine that ranks above 25cc should be big enough to handle most projects. Anything below that might be too tiny for commercial work and would, therefore, be best used for tiny, domestic tasks.
# Oil and Gas Mixing
Some old model 4-cycle trimmers required one to mix oil and gas when refueling. That, unfortunately, made them so difficult to manage. Fortunately, you can always tap into a machine that doesn’t involve this.
# Ease of Starting
Another common challenge with 4-cycle is that some require a few attempts to jumpstart. For that reason, it’s advisable to only go for a machine with minimal starter cord-resistance. Most importantly, you should only go for a machine that’s optimized to start easily.
# Shaft Type
The type of shaft you go for matters a lot as it influences how you handle the trimmer. A curved or bent shaft wouldn’t, therefore, be the best pick. It would be a good idea instead to go for a straight shaft. Typically, straight shafts are easier to maneuver.
# Noise and Emissions
There’s nothing as rewarding as trimming the hedge in a noise-free and environment-friendly way. But is it really possible to find a gas trimmer with such benefits? Well, it may not really be possible but we recommend going for one that’s minimalistic in both ways. It’s a good idea to go for a trimmer that operates relatively quietly. Most importantly, go for one that doesn’t emit too much carbon. Not only would such a machine be safe for the environment but also good for your health.
# Fuel Efficiency
Much as you’d like to go for a huge engine, it’s worth remembering that it may consume more fuel. Pundits recommend checking how efficient an engine is by listening in to different 4 cycle string trimmer reviews. By doing that, you can judge whether a trimmer provides you with an efficient run-time or not.
