Are Robotic Lawn Mowers Safe?
You’re standing in your front yard minding your own business when a robot with three razor sharp blades spinning at 5,800 rpm starts racing toward you. What do you do?
Is this some kind of nightmare? No, you’re awake and this is really happening, so once again, what do you do?
The answer is nothing. It will just bounce off you and go another direction. Rather anti-climatic ending wasn’t it? That is just the way the robotic lawn mower companies want it to be.
The greatest concern most people have about robotic lawn mowers is safety. ‘Bots with Blades’ just can’t be safe. According to Ames Tiedeman, National Sales Manager for Systems Trading Corp., the US distributor for the Friendly Robotics Robomower, over 72,000 emergency room visits involved lawn mowers in 2005. ZERO involved robotic lawn mowers.
These mowers have so many safety features and shut-off triggers that it is amazing that they are actually functional.
The Friendly Robotics Robomower turns the blades off at 16 degrees, not even high enough to get a hand under. Even if a small hand could get under, the blades are far back and recessed into a chamber in the body. It would take creativity, not stupidity, to get to the blades while they are still turning.
Unlike push and riding lawn mower safety devices, robotic lawn mower features are not easily disabled. The tilt detection devices are soldered on to the main boards. Even the resistance against the blades and the ability of the software to stop them is measured in thousandths of seconds.

Are Robotic Lawn Mowers in Your Future?
Robotic lawn mowers are going to be the next life-style changing appliance in America. Think about it, how many times have you wanted to get away for the weekend or go to some event but yard work kept you tied to the house? I can’t tell you how many golf outings I have missed.
Robotic lawn mowers can mow the yard, go back to the charger, and go back out again on their own without human intervention. This is a large step forward from only two or three years ago.
Residential robotic lawn mowers run on batteries, so they don’t use gas or oil. They are pretty much maintenance free except for the occasional replacement of the blades. They waterproof and they don’t rust.
A perimeter wire, like an invisible dog fence is placed around the yard to define the mowing area. Gardens, flowerbeds and trees can also be easily protected. Running the wire is not difficult, you can DIY or have it professionally installed. The wire can be buried up to 2 inches deep.
The robotic mowers must sense the presence of the wire around them. If the mower should somehow go past the boundary it will immediately shutdown, so you don’t have to worry about it running down the street (unlike your dog).

Aerating Your Customers’ Lawns
If your customers don’t have the thick, lush lawns they’ve imagined, you can rack your brain trying to figure out the cause. While you interrogate them about their watering practices and second guess yourself on fertilization, the problem might be a lot simpler. It might be time to aerate.
Are there tracks in the lawn? Are there tons of weeds despite a good fertilizer with weed prevention? Are pests becoming a problem? Is water pooling in the lawn after heavy rains? Are there bare spots that you haven’t been able to help? The soil might have compacted, and it might just take a little aerating to make the lawn thrive. If the customer has clay soil or it’s a dry area, you’ll need to aerate more frequently. There’s a simple and pretty unscientific way to tell when it’s time to aerate. Grab a stick. If the soil is difficult to penetrate with the stick, you should aerate.
You should choose a nice, clear day to aerate. If the soil is wet, you will have a huge mess and a lot of explaining to do to customers. You’re also going to get compacted soil much more quickly if it’s wet. If it’s too dry, you won’t be able to penetrate the soil with an aerator. Pay attention to the weather. You should have nice weather for as long as possible (a week at least) after you aerate for maximum benefits.
If you don’t yet have an aerator attachment for your mowers, you can rent one. I recommend renting them before you buy one anyway. There are different types of aerators with different features, and the best way to determine which you prefer is to try them out. Aerators with spreaders allow the plugs (or cores) of soil to be spread throughout the lawn. It’s fine to leave them, but they should be raked to make the lawn look better right away. If you have a lot of clay soil yards or live in a dry area, you want longer spikes on your aerator. You also want more spikes to play the odds. The more spikes you have, the more likely at least some will penetrate harder, dryer soils. In particularly dry areas, it’s a good idea to water a day or two before aeration, just to promote penetration. Then simply mow in the same pattern you were going to mow anyway, with the aerator attached.
