The first thing you need to look into while purchasing an auto lawnmower is the control features. This is especially important because the machine is expected to work without human intervention.

There is a possibility that it can be stolen from a yard.

Looking at all this Husqvarna 315X has an anti-theft GPS tracking mechanism inbuilt in the device which sounds the alarm if someone tries to lift the lawnmower from the ground.

It immediately alerts you that something is wrong. You need to enter the correct PIN again to resume the operations.

The only problem that people often face with the robotic lawnmowers is the installation of boundary wires. Boundary wires are important because they guide the machine to operate in a specific area and make GPS tracking possible.

Installing boundary wire is a difficult task if you have flower beds and trees around and in-between the lawn. The lawnmower has to be programmed to treat the same as hindrances and avoid cutting them.

Husqvarna makes this task easy for you if you opt to purchase the lawnmower through Amazon.

They arrange a professional who can do the job of installation of boundary wires with much precision and care.

Looking at the power source the professional installs the recharging station in your lawn where the unit can automatically return and get itself charged when it is time to recharge.

It is safe to use the product even when your children or pets are playing in the garden.

This is so because it has an anti-collision sensor that keeps it away from bumping in foreign objects.

The most important part of any lawnmower is the cutting blades. Husqvarna 315X uses three cutting blades that create grass clippings.

You need not worry about throwing the grass clippings as they act as a natural fertilizer.

This also eliminates the need for bagging and creates an environment-friendly solution.

The blades are powerful to cut the lawns in 0.4 acres and up to 2.4 inches in height. The company claims that the lawnmower can continue operating even in rains.

Some lawnmowers follow a straight cutting path which makes the cutting lines visible on the lawns.

Husqvarna 315X follows a random cut path and thus avoids those cutting lines trace marks on the lawns, giving your lawn a carpet-like look. Generally, lawnmowers have 7-inch cutting width but this model has 8.7 cutting width making a broad cut in every operation and making grass look smooth.

If you have landscape lawns then you need to specially take note of inclination angle. This lawn mower can cut the grass up to 22 degrees.
