How To Choose The Most Powerful Chainsaws?

#how_to_choose_intro

Gas vs. Electric vs. Battery-Powered Chainsaw

  • When compared to a gas-engine chainsaw, electric and battery-powered models have low operating costs and produce zero noxious emissions. Whether you are a beginner or a veteran, expect to operate your electric/battery-powered chainsaw within seconds. No need to deal with pull cords and gas & oil mixing as well as the mess and the harmful fumes.
  • However, gas-engine chainsaws can deliver way more power than any other variant. Their chain is not only tougher but also spins faster, thus ensuring quicker cuts through wood.

Electric vs. Battery-Powered Chainsaw

  • Electric chainsaws can be either corded or cordless battery-powered. User’s mobility is the biggest factor that differentiates these two types from each other.
  • If you prefer the unit with a power cord connecting it to the mains socket, don’t expect to move around a lot. However, it is a bit more powerful, and you do not have to worry about running out of power. Meanwhile, the cordless battery-operated chainsaws are really portable and allow users to go virtually anywhere they want.

Blade/Bar Length

When shopping for a chainsaw, blade/bar length which determines the thickness of a wood piece your machine can cut is one of the most important features to consider.

That way, it affects the types of woodcutting projects you can perform, from firewood slicing up and tree taking down trees to branch cutting down.

To choose the proper blade length for your yard projects without compromising your safety, a rule of thumb is to use a model with the blade at least 2 inches longer than the branches you want to cut.

The most popular chainsaws’ lengths are:

  • 12 to 14 inches - associated with branch trimming and pruning tasks

  • 16 to 18 inches - meant for small tree felling and firewood cutting up

  • 20 to 24 inches - considered as professional-grade - built for larger tree felling and thicker log slicing
