ECHO CS 400 Review

The predominant word with the Echo 40.2cc Chain Saw with i-30 Starter and 18-inch bar is ‘dependable.’

It is more powerful than many of its contemporaries and can make quick work of branches, tree trunks, logs, and brush.

The operation of the machine is also seamless. It is well balanced and has enough power to handle a larger bar.

The startup is quick and easy, regardless of whether the machine is hot or cold. The spring-assisted start and dual ignition make it easy for just about anyone to get the chainsaw started.

ECHO CS400 Alternatives

Here are 3 of our favorite alternatives to the CS400, but ECHO is also well known for their top handle chainsaws.

1. Echo 30cc Gas Chainsaw (here on Amazon)

Echo has a 30.5cc gas chainsaw with a 14-inch bar.

Its engine is 2 stroke and the chainsaw has a gas tank capacity of 8.5 ounces. The overall weight is 6.42 lbs. This chainsaw is ideal for smaller cutting jobs, including cutting wood for a fireplace or woodstove. It has less power than the Echo CS-400.

The ECHO CS-2511 T is another great lightweight chainsaw.

2. Husqvarna 435e II Gas Chainsaw (here on Amazon)

This machine weighs 9.2 lbs and provides 2.2 horsepower.

It is a nice ‘split the difference between the Echo CS400 and the chainsaw above.

It also comes with the Husqvarna reputation for dependability and toughness, which is an industry-standard. This Husqvarna is on par with the CS-400.

3. Husqvarna 460 Rancher Chainsaw (here on Amazon)

For those looking for a larger model, Husqvarna has the 24-inch 460 Rancher Gas Chainsaw.

This monster runs off a 60.2cc 2-cycle engine with an air injection system as well as an adjustable oil pump. It is expandable to 28 inches and engineered to reduce fuel consumption and emissions.

This chainsaw is more powerful than the CS-400. If you have an extremely large job that includes logs greater than 20”, the 460 Rancher is the best way to go.
