Ryobi ry40180 Review

If you’re looking for the quietest, lowest maintenance, most straightforward to use lawn mower that runs on batteries, this could be it. This Ryobi eco-friendly model has all of the above, and it does an excellent job cutting grass in most situations. 

A robust 5Ah lithium battery powers the unit, and the battery compartment has a second slot for a backup battery, giving you well over an hour of runtime. The unit comes with one battery and a charger, and one of the few downsides of this mower is the cost of buying replacement batteries. 

Turning this mower on is ultra-simple:

  1. Drop a fully charged battery into the slot on top of the mower and close the compartment.
  2. Insert the key into the space near the battery.
  3. Push the start button while pulling the bail on the handlebar, and you’re ready to go. 

An automatic throttle uses advanced load-sensing technology to adjust the power and speed of the unit according to the cutting situation. So when the grass gets thick, you don’t have to do anything to ramp up the power. By automatically raising and lowering the power output, this motor uses energy highly efficiently, increasing overall runtime. 

The high-quality brushless motor design is capable of powering the mower through tall grass, and it can also keep the blade spinning to chop up and bag dry leaves and small plant trimmings.

You can collect the trimmings in the included collection bag that snaps on the back of the mower, reducing the volume and making it easy to dump for disposal or use as mulch or an ingredient in the compost pile. 

Another feature of this mower that is an advantage for many buyers is the ease of assembly. Essentially, all required is to remove the unit for the box and packaging, adjust the handle, charge up a battery and insert it in the battery compartment, and start the mower.

In addition, storage is equally simple because the handlebar telescopes down and then folds up completely, and the device has a small footprint, made even smaller if you store it on end. 

The deck height quickly adjusts using a single-point lever, setting the deck to seven different positions for a cut between 1 ¼ to 4-inch high. The narrow 20-inch deck width lets you readily steer the mower into tight spaces around buildings, paths, and plants. In addition, the 3-in-1 feature allows for catching the clippings in the bag, mulching them under the mower, and discharging them from the side chute. 


Main Product Features

– Battery 

This mower comes with one Ryobi 40-volt, 5Ah battery, and a charger. The battery is compatible with all other Ryobi 40v tools. However, it cannot be used with other tool brands or chargers. The interchangeability of the battery in this tool with other Ryobi equipment is an advantage for buyers who have other Ryobi tools or plan to buy them. 

The precise amount of runtime for a battery depends a lot on the mowing conditions, with small cuts on dry grass giving the longest and cutting tall wet grass the shortest battery runtime. Runtime for one 5Ah battery averages between 30 and 90 minutes, depending on cutting conditions.

These batteries are guaranteed for three years, and this is an above-average lifespan for a battery. The battery guarantee on this product is a significant plus for anyone concerned about the cost of replacement batteries. 

The brushless motor is also designed for durability and power. This type of motor runs cooler and does not have the problems with friction found in motors with brushes. The brushless motor also allows this machine to ramp up the energy output when the cutting conditions get more challenging. 

The electric start mechanism turns on the mower and blade with nothing more than pushing a button while holding down a lever. Compared to gas mowers with pull cords, chokes, spark plugs, and smelly fuel, this lawnmower is a breeze to operate and maintain, making it perfect for buyers with less experience using lawnmowers.  

– Cutting Deck

Adjusting the cutting deck height is crucial for getting a good cut and maintaining the lawn’s health. It’s usually best not to cut grass more than one-third of the growth length, or it can reduce the lawn’s vigor and appearance. With seven settings to choose from on the deck adjustment on this mower, you can select the exact cutting height you need for your lawn the day you mow. 

The collection bag that comes with the machine readily snaps on the back of the mower without using any tools. It’s also easy to pull it off to dump it. As long as you’re cutting dry grass, the bag fills up to the top without getting clogged. 

For mulching instead of bagging, remove the collection bag and install the mulching plug that comes with the unit. Some buyers note that installing this plug can be challenging, and if it is not inserted correctly, it can interfere with the blade.

For side discharge, remove the bag and the mulch plug, and trimmings shoot out of the side of the mower as you move along. The owner’s manual describes how to convert from mulching to bagging and side discharging clippings properly.  

– Ergonomics and Storage

If storage space is one of your concerns, this Ryobi lawn mower is one of the most compact units around. It folds up neatly and without any tools or hassle by turning a knob and telescoping down the handlebar, and then folding it over the top of the mower. After that, you can also tilt the machine up onto its nose and store it upright for maximum space-saving

The handles also have multiple height settings in the telescoping section. They adjust in two positions where the lower part of the handlebar meets the mower’s body, giving you a wide range of options for getting just the right setting to match your height and physique. 

Another handy ergonomic feature is the LED headlamps, which are rarely available on a push-style mower. The lights let you safely work in low light conditions during early morning and late evening hours. In addition, they stay on whenever the machine is running, so they also offer a safety benefit around pedestrians and traffic in driveways and parking areas. 

Another convenience of this mower is how easy it is to keep clean. However, the deck does not have a washout port, so you must turn it over to clean underneath.

Beyond this, virtually no other maintenance is required on this mower except properly storing and charging the battery. Compared to a gas lawnmower, this unit is ultra-simple to maintain from season to season: a significant benefit to buyers who don’t want hassles and mess, along with keeping the lawn trimmed.  

– Size and Weight 

The unit measures 59-inches long, 21.5-inches wide, and 39-inches high, with the handlebar extended. When it’s folded, the height reduces to approximately 26-inches, low enough to slide under a workbench or shelf in the garage. 

The mower weighs a modest 45 pounds and is light enough for almost anyone to move around on the flat ground easily. However, despite the low weight, it could still be hard for some people to push uphill because this is a manual push mower without a self-propel function.

In this case, a battery-powered self-propelled mower might be a better choice.  

– Warranty 

This Ryobi 40 volt lawn mower comes with an exceptionally extended limited warranty of 5-years for the mower and 3-years for the batteries and charger. This exceptional warranty benefits anyone who wants to invest in a battery-powered mower without worrying about performance over a reasonable tool lifespan.
