Most users will appreciate this affordable mower compared to a gas-powered mower and other electric models.

You’ll find it effortlessly navigates around corners, driveways, and patios to achieve the perfect lawn height.

The specific amount of cutting time you’ll have is dependent on the thickness and quality of your lawn. However, most users have found the battery stays strong for properties up to ¼ of an acre. Also, it features a built-in battery, so simply plug the unit in to recharge it at the end of your job rather than recharge additional batteries.

  • Adjustable Cutting Deck

Customizing the height of your eco-friendly cordless lawn mower is essential for tailoring the professional look of your lawn. With that said, the Sun Joe MJ401C 14-Inch Cordless Push Lawn Mower has an adjustable cutting deck. There are three different positions to choose from, making it easy for beginners to use.

The cutting adjustments are entirely manual to have a hands-on approach. You have to use the integrated lever to find the ideal cutting height.

  • Included Safety Key

The safety of the outdoor equipment you keep in your garage is essential, especially if you have small children and pets. Fortunately, this cordless brushless lawn mower kit comes with a safety key that’s needed to use the mower. Users must insert the key before turning the lawnmower on and remove it after you’re finished.

  • LED Battery Level Indicator

When cutting your lawn using an electric mower, dealing with a dying or dead battery can be challenging. Most models don’t indicate when it’s time for a charge, but this model is innovative. You’ll find an onboard LED battery level indicator, keeping you apprised of your remaining cutting time.

You’ll have to engage the built-in push button to check the battery. This feature allows you to easily look at your battery consumption during the job.

  • Detachable Grass Catcher

Most property owners will find the basic package for the Sun Joe MJ401C 14-Inch Cordless Push Lawn Mower ideal. You won’t need to buy any additional accessories as it comes with a detachable grass catcher. You’ll be able to hold up to 40L of grass clippings, keeping them off your lawn.

The grass catcher is uniquely designed for convenient disposal. You’ll have a built-in grass indicator window, helping you know when to empty clippings. This feature is essential, especially with affordable lawn mowers.

  • Instant Start

Gone are the days when you would have to handle a finicky pull cord to start your mower. With this model’s fully electric design, it starts up instantly, helping you get to mowing far faster. Also, with its high-quality brushless motor, you won’t have to worry about maintenance during the season or any pre-season tune-ups.

  • Quiet Cutting

Thanks to its integrated motor, you’ll find you might not even need ear protection while managing your cutting path. It’s guaranteed that your neighbors will appreciate this model compared to older gas mowers.

How to Use This Mower

The Sun Joe MJ401C 14-Inch Cordless Push Lawn Mower is often regarded as one of the easier battery-powered mowers. Instead of having external batteries, it has a built-in unit, making it simpler to charge. The other features are also easy to use, especially if it’s your first time.

Step 1: Assemble the Mower

The essential components of the mower come preinstalled, such as the equipment in the cutting head. However, you’ll likely have to attach the handle bar to the bottom half of the unit. Using the included instructions, this process is quite simple.

Step 2: Charge the Battery

The next step in getting your new mower ready to be used is to charge the battery. It is a built-in lithium-ion battery that doesn’t require a third-party charger. Instead, all you have to do is plug the unit into a wall socket for it to charge.

In most instances, this entry level mower takes only four hours for its first charge. After four hours, unplug the device and run it until the battery is dead. After this process, you can give it another full charge before putting it to work.

Step 3: Adjust the Mower Deck Cutting Height

Before jumping into mowing, you must first adjust the mower deck cutting height positions. For this process, the mower needs to be on its side so you can have access to the adjustment tools. There are different settings for the 3-position height control built into this unit, which includes:

  • Low: 1.18 inches
  • Medium: 1.93 inches
  • High: 2.52 inches

You’ll need to pull on the rod axle and sit it to the position you need to make adjustments. All four of your wheels will then move to the appropriate grass height. Once this is done, you can continue with your startup steps.

Step 4: Start the Mower

Once your battery indicator shows you it’s fully charged, it’s time to start your battery-powered lawn mower. First, you’ll need to insert your safety key into its respective slot; otherwise, it won’t come to life. After inserted, tilt the handle down so the front of the mower is raised to prevent accidental cutting.

Next, you’ll need to press and hold the safety lock button located at the base of the switch lever. Also, engage the switch lever by pulling it towards you. This process will turn the mower on, and you can release the safety lock button, lowering the mower.

Step 5: Clean and Store the Mower

Once you’ve finished maintaining your lawn, it’s time to store the mower away. You must ensure all clippings are removed and clear the cutting blades. This helps protect the quality of the mower while also preventing rust and dirt buildup on the durable steel blade.

It’s also essential to empty your clippings bag of any caught debris. Always ensure you don’t use high-pressure water to clean your lawnmower, which can damage the cutting blades over time.
