best robotic lawn mower for large lawns

Everybody’s working for the weekend… but no one wants to work on the weekend. Saturday and Sunday are the time to rest and enjoy your family and neighbors. Reclaim your weekends from the dreaded burden of mowing and celebrate all the reasons you wanted that big ole’ yard in the first place. Enter the best robotic lawn mower for large lawns!

Forget about paying someone else to mow your yard or worse yet – sweating it out yourself. A robotic mower will do everything but drink your beer for you. Large yards can be timely to maintain yourself and costly if you hire a team of landscapers.

While robotic mowers carry a heavy price tag, they’re worth their weight when compared to the average $300/month it costs to hire someone to maintain an acre lot. Calculate the cost of your personal time, lawn bags, gas, and a riding mower and it is easy to justify substituting a robot mower.

Here’s a sneak peek of the robotic mowers we are about to cover.

How Does a Robotic Lawn Mower Work?

A robotic mower, on the outside, operates a lot like a robotic vacuum or mop you may have in your home. Both are battery operated and go back to their base when they are in need of a recharge. Once they’ve booted up, they can run anytime day or night. That’s right. They run even as quietly as your Roomba.

Similar to vacuums and mops, you, the operator, must establish perimeters. With robot mowers, perimeters are outlined with a staked or buried wire. The actual bot itself uses sensors that detect trees, shrubs and ornamentals as well as the wires to keep it from roaming off your property and getting into mischief.

When you watch your bot from behind your steaming coffee cup, it may seem like it is going willy-nilly with no sense of direction and you may feel nervous about the outcome of your cut. Don’t fret – the sensors also tell the mower where it has been. In due time, your yard will look professionally and evenly trimmed.

Some bots are Bluetooth and Wi-Fi compatible. This makes it possible to start or stop your mower from anywhere from your mobile phone or tablet. Most robotic mowers require very little maintenance. It will do the hard job and all you have to do is clean and change the blades from time to time. However, mowing after or during a good rain can cause grass build up and damage the mower and be a pain to clean.

If it weren’t impressive enough to watch a robot cut the grass, these high-tech bots mince grass clippings so fine no bagging is required! Instead, the used grass goes back into your lawn, unnoticed, and acts as a natural fertilizer.

What to Look for In Your Robot Mower?

For a larger yard, you will need a mower that has a higher capacity battery life than most. The biggest lot a consumer grade robotic mower can mow is up to approximately 1.25 acres before needed to recharge. Commercial models can go as far as 5 acres but they’ll set you back 5 figures.

You can also opt to cut your grass in separate zones and schedule them to run at different times. You’ll need to make sure your new whip has a multi zone feature before purchase. To speed up the process, look for a mower that has a larger blade width. They come in sizes up to two feet to make bigger passes.

If your hard has steep inclines, you’ll need a mower that has larger wheels and can easily adjust to the slope. The steepest incline for a mower is approximately twenty-four degrees. Although, there are a couple Husqvarna models on the market that boast a forty-five-degree capability.

If you don’t want to mess with wet, clumpy and sharp blades, be sure to find a mower that has a rain sensor. If I can stress an important feature, I’d favor this one. Just because a robot can operate in the rain doesn’t mean it should. Just like any ordinary lawn mower, it is only going to cause you heart ache and pain when you go to clean it up… and that is if it didn’t cause any damage underneath!

Drawbacks to Robotic Lawn Mowers

While some manufacturers come out and help, or send a qualified technician, you may be on your own for the install and set up of your perimeter wires and mower. If they do help, it’s going to cost you a pretty penny.

Depending on the size and complexity of your yard, you should plan on spending a good several hours on your knees setting up and burying the perimeter.

Should you have a multi zone set up, it will require extra time to plan out your yard into each section. Then, you are able to set about establishing perimeters and boundaries. If your yard has obstacles such as mulched beds, or holes (which these tiny helpers tend to get stuck in) account for this, as well.

Lastly, if a wire accidentally gets cut or damaged, it can prove to be very tedious and time consuming to find the compromised area and expensive to repair.

Conclusion

If you have a huge one acre lawn (4840 square yards) that needs regular maintenance, you can’t go with the Husqvarna Automower 450XH. For yards around half an acre and a tighter budget we’d say…

“Alexa, order up a Worx WR150 Landroid L Robotic Mower!” This robotic mower takes care of your yard and itself.

It really doesn’t get any easier with its smart features that allow it to learn your yard and suggest the most efficient mowing schedules, rain detection, and large cutting width. The 9-inch cutting width allows it to cut close to edges and cut the time it takes to get the job done.

It has five height settings to adjust how closely you want your grass cut. It’s comparably priced and a strong contender in the robotic mower market. It offers all the features and specs of the higher priced mowers and operates like a champion in its own class.

Multi zones may be formed by making your own wire perimeters and physically moving the mower, if your yard requires. If it falls in the half acre perimeter, though, the Worx Landroid L is an impressive product.
