Design of the Sun Joe iON16LM

Weighing just over 34-pounds, the Sun Joe iON16LM is designed for mobility, both on the lawn and off. The smaller deck size (16-inches) and large rugged wheels help the mower maneuver around landscaping and other obstacles while you're cutting your lawn. And whether you're looking for additional maneuverability when mowing to avoid an obstacle, or you need to lift the iON16LM for storage or transport, the lifting handle behind the battery pack is incredibly convenient.

The cutting height lever is located on the side of the mower and it adjusts the cutting height for all 4-wheels simultaneously. There's 6 cutting height positions to choose between, which range between 1.18- to 3.15-inches.

The push handle can be easily adjusted up or down to the users preference by using the multi-position, quick-lock wheel on the side of the mower deck. The handle is covered with foam to reduce vibrations and provide a comfortable grip. Steel is used for both the upper and lower bars.

Power Source

Like most battery operated mowers, the battery compartment is located in the center of the mower and is protected by a plastic cover which locks into place. The battery is easy to install and "clicks" when inserted and the spring-activated design makes removing the battery simple. Press the battery into the compartment until you feel the spring kick-in, then press the push lock and the battery moves above the locking position where you can remove it from the compartment.

Once the battery is in place, a safety key needs be inserted in order to operate the mower. This is a nice added safety feature which prevents unauthorized use of the mower.

The Sun Joe iON16LM lawn mower uses a 40 Volt, 4Ah lithium-ion battery. The mower can be purchased with the battery and charger or, if you have other tools that use this battery, you can buy the bare tool only and save a few dollars. Additional batteries are also available for purchase. 

The battery takes between an hour-and-a-half and two hours to charge, and should remain on the charger for no longer than 3 hours. You can expect roughly 20-minutes of run time on a fully charged battery.

Operation

To start the mower, adjust the cutting height, insert the battery and safety key, then close the battery compartment. Hold the safety lock button which is located on the side of the handle and pull the switch bar lever (bail) towards you. When the motor begins running, release the safety lock button. Once you have finished mowing, simply release the switch bar lever and the motor stops.

The 600 Watt brushless motor offers reduced noise and a longer service life over brushed motors. In addition, they are more efficient and reliable. As a general rule, brushless motors have a higher torque to weight ratio, which means the performance is excellent and the mower is lighter.

The grass bag, which catches the clippings, attaches to the rear of the mower. When the bag is full and needs to be emptied, a flap will close to alert you.

When the mower is not in use, the handle folds down so the tool can be easily stored in a garage or shed.

Performance

The Sun Joe iON16LM cordless mower is designed to tackle lawns of under 4,000 square feet. If you have a larger lawn, you'll need to invest in additional batteries or mow in stages while your battery charges.

The 16-inch deck and 15-inch blade is a great size for smaller yards since it makes the mower very maneuverable and does not add bulk or weight. Although, it will require more passes when cutting, but larger mowers are often difficult to use in small yards, so the trade off is typically the better option.

The iON16LM can handle a variety of grass heights and still deliver a clean cut, and, although not recommended, it performs reasonably well on damp grass too. 

The mower is easy to use and operate regardless of your physical size. It's ideal for first time mower owners and is a favorite among experienced mowers as well.

Maintenance

All lawn mowers require maintenance, but electric mowers need far less. In the Spring, add a little lubrication to the wheels, and check the condition of the blade (sharpen or replace as needed).

Then after each use, you'll need to clean the grass bag, and wipe the clippings and debris off the mower. Use a dry cloth or brush to remove the clippings from the deck area. If needed, you can use a damp cloth and non-abrasive soap. However, never use a hose or harsh cleaners.

Warranty and Customer Support

The Sun Joe mower comes with a standard 2-year warranty from the date the mower was purchased by the original end-user. If the product is registered on the Snow Joe + Sun Joe company website, you'll receive an additional 90-days of coverage, although you can also send in a registration card if you prefer that method. For a small fee, you can purchase up to 3 additional years of coverage.  

The warranty does not cover the mower if its been used commercially or for non-household or rental applications, or if it was purchased from an unauthorized seller. Normal wear-n-tear on parts such as belts, augers, chains, etc. are not covered.

A company representative can be reached 7-days a week at 1-866-766-9563, by email, social media, or through a chat box on their website. The company proudly states that they provide top-tier customer service and no hassle returns.

Final Thoughts of the Sun Joe iON16LM

The Sun Joe iON16LM lawn mower offers good performance in a compact package. It's safe to say that the mower is positioned near the mid-range, which makes it a solution that would appeal to a wide range of users.

If you're looking for a low maintenance, small, light-weight mower that offers good cutting performance and battery life, then the iON16LM is a good option and well worth your time.

It should be noted that there is a newer version of this model (Sun Joe 24V-X2-17LM) which uses a different battery pack, has a larger cutting path and some other nice features that are not present in the iON16LM.

Pros

  • Lifting handle on the body of the mower makes moving the mower easy and convenient 
  • Extremely maneuverable and easy to handle
  • Adjustable height handles allows the user to find the best position for their individual needs

Cons

  • The only grass clipping option is a rear catch bag, no mulching or side discharge
  • The rear catch bag needs to be in place in order to use the mower, and because it is only 9.26 gallons, it requires frequent emptying. A larger grass bag would be a nice option
  • The battery compartment must be opened in order to check the battery power level. This can be rather inconvenient
