  • Powerful and Reliable Chainsaw for Heavy Duty Work
This 58cc Gas Powered Chainsaw is built for serious cutting, and it doesn’t disappoint. The quick-switch 20” and 18” bars give it great versatility, whether I’m handling large logs or trimming smaller trees. Chain tension is simple to adjust and holds steady during use, which really improves efficiency. Durability is solid—the build feels rugged and dependable, able to handle repeated use without wearing down fast. Despite its size, the weight is balanced well enough to keep control manageable, though it’s definitely more of a workhorse than a lightweight saw. The cut quality is excellent—smooth, fast, and consistent, even through thicker wood. The power from the 58cc engine is impressive, giving it the strength to slice through hardwood with ease. Functionality is boosted by the automatic chain oiler and centrifugal air filter, which help keep maintenance low and performance high. Starting is quick and reliable, and the inertial chain brake adds an important layer of safety. Overall, this chainsaw combines raw power with useful features, making it a great choice for anyone who needs a dependable tool for both big jobs and regular yard work. ... show more

  • Might have to reattach the pull cord.
The saw cuts good, although it should as the chain is new. Second time I tried to start the saw the pull cord came undone. Had to disassemble part of the saw and reattach the pull cord. Not something you ahould have to do to a new saw. Very disappointing. Spent more time fixing the saw than using it. ... show more

  • Professional Powerhouse with Quick-Switch Versatility
This WTHW 58cc chainsaw is an absolute professional-grade powerhouse that delivers flawless cutting performance right out of the box. The quick-switch system for the 20-inch and 18-inch bars makes adapting to different logging jobs incredibly fast and convenient, adding immense value. Starting is quick and reliable, while the centrifugal air filter keeps the engine running strong even during long, demanding sessions. Safety is top-notch thanks to the inertial chain brake, and the automatic chain oiler ensures the blade stays optimally lubricated without constant attention. For serious firewood processing or extensive yard clearing, this saw is a top-tier investment that easily earns my highest recommendation. ... show more

  • Works as it should be
The media could not be loaded. This chainsaw is powerful and easy to use. It starts with one pull, which is vey convenient. The 20" and 18" bars are easy to switch, and it cuts through thick wood smoothly. The automatic oiling system works great and keeps the chain running well. It feels strong, safe, and reliable — perfect for yard work or cutting firewood. Very happy with this purchase! ... show more

  • Powerful and reliable!
Powerful and reliable! This 58cc chainsaw handles tough jobs with ease. The quick-switch between 20" and 18" bars is super convenient, and it starts easily every time. Great features like the auto oiler and chain brake make it safe and smooth to use. Excellent value!

  • Don’t do it
Do not buy this. The blade comes off. It is dangerous. When the bolts are tight enough to not come undone, the blade won’t turn. Loosen them and it vibrates off. Save your money.

  • Best thing ive bought this year.
I love this chainsaw. Its efficiency is off the charts and its power is also amazing. It requires little to no effort to use with a good grip ensuring your safety and its design cuts out the chain’s tension that other chainsaws fail to do. For something so sharp and lightweight, this is defiantly a good pick for any projects or yard work. ... show more

  • Works good, light and easy to use.
Like it, the clear instructions made assembly easy, it started right up and worked perfectly. light weight for daily use. Powerful compared to my electric saws, with adjustable chain tension and two chain sizes included, i think it's great value!
