Cutting grass with an electric mower is very similar to cutting grass with a gas-powered lawnmower. However, there are a few differences to consider when making the switch, especially if you are used to working with a manual real lawnmower.
Step 1 - Consider Safety First
As with any lawnmower, it is important to remove any objects from the yard before starting. Running over these things can damage the mower and stepping on them can cause an accident. Always wear proper non-slip footwear as well as eye protection and remove any loose articles of clothing or jewelry.
Electric mowers are quiet enough that you don’t have to worry about wearing hearing protection. However, these models are less tolerant of wet grass than others. Wet grass will slow down the blades, forcing the motor to push harder, which can not only damage the motor, but also drain your battery or pop your circuit breaker.
Step 2 - Start Up
For a battery-powered mower, be sure that the battery is fully charged before using it. This is especially important if this is the first time you’ve charged the battery, as rechargeable batteries will suffer a loss in their ability to retain power or charge all the way if they are not fully charged the first time. Connect the battery to your mower, ensuring that all the connections are secure.
If your electric mower is running off a power cord, be certain that the cord is long enough to reach wherever the mower needs to go. Use an extension cord if necessary, and make sure that all cords are securely plugged into their outlets.
Step 3 - Mow
Electric mowers, especially those running on batteries (as opposed to power outlets), do not have as much power behind them to spin the blades. Therefore, the mower should not be used to cut especially heavy, overgrown grass. You may need to make multiple passes for grass that is long and thick.
It is very important that you always be aware of the location of your power cord runs and that you mow away from it. Running over the cord can damage your blades and motor and/or slice the cord. You also do not want to risk tripping over the cord.
Cordless mowers are safer than outlet-powered mowers at the expense of running time. These mowers are ideal for smaller yards (a ¼-acre at the most), as anything else will require you to stop to let the battery recharge.
When you are running low on power, the blades will noticeably have less force behind them, and the cut grass will begin to look choppy. If this happens, turn off your mower and recharge the battery. Otherwise, you risk doing damage to the blades and the motor.
