How to Install a Perimeter Wire for Your Automatic Lawn Mower

The thought of owning an automatic lawn mower is always great and the mere fact that you will be able to have a properly done lawn without your supervision is just exciting, isn’t it? Not so fast. The above statement is entirely true until you realize that there is always more than what meets the eye.

Note, you are only able to use your automatic lawn mower after you have marked your perimeters and this involves installing a perimeter wire. If you are using an automatic lawn mower for the first time, one of the challenging tasks you’ll find is getting the perimeter wire right. Since the perimeter wire is round on the outside to help stop your robot mower from leaving the lawn, you cannot afford to get this wrong.

How to Install the Robotic Mower Perimeter Wire

The truth of the matter is that not all lawns are of the same shape and size. The way you install your perimeter wire depends entirely on the shape of your lawn and the obstacles around it.

Placing the Perimeter Wire around a Rectangular Lawn

Ideally, most lawns are always rectangular in shape. When installing a perimeter wire for your automatic mower in such a lawn, two things are always of importance: getting enough wire and knowing what to do with the corners.

The former is pretty easy. Measure the perimeter of your lawn and buy a wire of equal length. Once you have the wire, clip your perimeter. Note, as the manual says, always avoid sharp corners. Also, watch the distance between the edges of your lawn and the perimeter wire. Avoid the false temptation of getting close as possible to the edge of your lawn since your mower needs adequate space to turn least it exits the mowing area or bump into a barrier.

The Perimeter Wire and Obstacles

When installing your perimeter wire, you should also understand that it is possible to branch out and use your wire to go around obstacles such as a tree or a flower bush. When doing this, you need to watch out that the wire is double back so that your mower ignores it. By failing to observe this simple rule you might end up getting your lawn mower stuck at the edge of the mowing area and restricted by the outgoing wire.

Inasmuch as the above strategy works effectively, the ideal situation when installing a perimeter wire for an area bound by lots of obstacles would be building a small wall. Apart from this being a simpler option, it helps reduce the amount of wire being used and importantly reduces the risk of damaging your lawn mower since you will have eliminated most of the hazards.

Setting Up The Perimeter Wire with Multiple Zones

Sometimes when installing a perimeter wall, you are faced with a lawn with multiple zones. One point to take home is that when you have a zone that is not reachable by your robot lawn mower automatically, it is always safe to carry it to the other zones.

When it comes to the other zones, you can create a perimeter wire for the first zone by taking off the wire from the charging station then pass it along the edge of your boundary- be it a passageway or fence- and completely bound your lawn.

For the second zone, run your perimeter wire around the edge of the first zone then go along the edge of your boundary and bound your second zone before returning the wire back to the charging station. Ideally, the gap between this two wires is always close, precisely less than a meter. This isn’t good as sometimes your automatic mower fails to mow the second zone or gets stuck in the second zone. However, until an ideal solution is found, abide by this procedure.

Automatic lawn mowers can be easy and very convenient for your lawn purposes if only you get you install your perimeter wire right. Though this might be challenging if you are starting out, the above guide provides you with a comprehensive analysis of how to go about it.
