Lawn Boy mowers: Lawn Boy 10606

The Lawn Boy mowers brand is owned by the famous Toro company which gives me a fair bit of confidence in Lawn Boy mowers.

This Lawn Boy 10606 20 inch lawn mower is certainly worth checking out if you need a tough and dependable walk behind lawnmower, with a good selection of features at a reasonable price.

The Lawn Boy 10606 comes standard with electric start and self-propulsion, plus it is able to accomplish three distinct mower functions – it bags, mulches and side discharges. This makes it incredibly versatile, especially for users who appreciate having more than one cutting function.

That said, this mower excels as a mulching mower, so if that is your preferred way of mowing, this Lawn Boy may be just what you need.

The 10606 also features a powerful and reliable Kohler engine that supplies enough torque to efficiently rotate the cutting blade while supplying power to the self-propulsion system.

Lawn Boy mowers are known for being dependable and effective, and this model is no exception. Though it can usually be purchased for somewhere between $330 and $350, it is built to compete with mowers with much higher price tags.

What can the Lawn Boy 10606 be used for?

(Back to Top)

First, to quote the user manual, this mower is:

“to be used by residential homeowners or professional, hired operators. It is designed primarily for cutting grass on well-maintained lawns on residential or commercial properties. It is not designed for cutting brush or for agricultural uses.”

Obviously, there are bigger and mower powerful mowers, like our recommended Honda HRX21HZA and the Husqvarna 7021R , but this Lawn Boy mower is lighter and more maneuverable than those mowers, thanks largely to its compact 20 inch deck.

The 10606 is set up to bag, mulch and side discharge, although its deck design makes it better suited to mulching than standard decks on other mowers.

You can operate the mower in a variety of different terrains and get good results. However, the 10606 is probably best suited for small to medium sized yards and properties. It is also well suited for mowing smaller areas of yards which riding mowers may be unable to reach.

The Lawn Boy 10606 comes with a self-propulsion system that features rear wheel drive. Believe me, this takes a lot of work away from the process of cutting grass – especially when your grass is long or you yard is full of slopes.

Because of the rear wheel drive function, you can mow slightly rougher terrain pretty easily and quickly too. If you have a yard that features some uneven ground, you should find that this machine cuts through the grass in such areas pretty effectively.

But as the manual says, don’t expect it to work like a brush cutter.

The 10606 Lawn Boy mower’s engine

Kohler is one of the top names in small engines, and this Lawn Boy is fitted with one of Kohler’s most dependable products a 149cc Kohler OHV engine with 6.5 foot pounds of torque.

It is a quiet and efficient engine that supplies plenty of power to spin the blade and operate the self-propulsion system. The engine also features the innovative Smart Choke system, which eliminates the need for users to prime the engine prior to starting.

Starting the engine is extremely simple. All you need to do is turn the key for the electric start system, and you will be fired up in moments.

If you prefer to use the recoil starting system, you will be pleased to know that the 10606 usually starts on the first or second pull of the cord.

One other important feature of the engine is its Easy Fill fuel intake, which effectively eliminates spills when fueling the machine.

If you have ever spilled precious gasoline while trying to fit the spout of a heavy gas can in an engine’s intake, you will be happy with this feature.

Handling and operating the Lawn Boy mowers 10606

(Back to Top)

Lawn Boy mowers are known for being well-built and properly balanced.

The 10606 is exemplifies this in that it is very easy to handle. Although the 20 inch cutting width may be narrower than some other mowers, the compact design of the deck actually increases maneuverability.

This makes it easier to get around obstacles such as trees, flower beds, narrow access ways etc. In fact, where you have those condition, the benefits of having the smaller deck will become self-evident.

As indicated above, the lawn Boy 10606 has the luxury of electric or recoil starting mechanisms. Then, once you get the mower started, operating it is relatively effortless given its self-propelled rear wheel drive operation.

You can also easily vary the speed you mow at, so you can always find the correct speed for your conditions.

Cutting features

(Back to Top)

The Lawn Boy 10606 features a powerful tri-cut blade that is able to handle mulching, side discharge and bagging.

When you unpack the machine from its box, it is ready to do all three of these functions, but you’ll need to purchase an additional attachment for side discharging.

The 20 inch deck is made of steel that is formulated to be light, yet strong and durable.

The Lawn Boy’s deep dome deck create more of a vacuum effect than other mowers.

This means that grass clippings are sucked deep into the deck while the mower is operating so that they can be chopped finely by the blade. This is especially useful for mulching and is what makes this a great mulching mower.

If you prefer to bag your clippings, the included bag assembly is very simple to attach and remove as needed. The bag might be somewhat small in size, but it gets packed with clippings tightly and efficiently so that you do not need to empty it an inconvenient number of times.

Cutting height is easily adjusted in seven positions between one and four inches.

    (Back to Top)

    This mower has been reviewed a total of 23 times on and it has earned an average score of 4.1 out of five stars, which is an outstanding score. Eleven reviewers gave the machine a five star rating, while five people gave it scores of four stars and 5 people gave it three stars. Only two reviewers gave it a two star rating, and no reviewers were dissatisfied enough to rate it at one star.

    There’s a pretty similar picture at Home Depot, where out of 50 reviews, it averages 3.9 out of 5.

    The positive reviews tend to point out how easy the machine is to use as well as how simple the electric start system works. Users have lauded the mower’s dependability, as well. One reviewer made a point to state that the machine runs quietly.

    Negative aspects of the reviews have tended to center on the packaging of the mower. Apparently, the packaging of the machine can lead to damage during shipping. In most cases, the consumers have been able to correct any negative aspects stemming from the lack of high-quality packaging.

    Here are extracts from a couple of the Amazon reviews:

    Finally, a great mower that you can rely on. This mower starts first pull every-time. I usually start it with electric start though. The adjustable height for the mowing deck is easy to adjust, since I have to adjust it all the time. The engine is very powerful and it hasn’t bogged down on me through the toughest grass. The self-propelled feature is great and I can’t imagine not having it. The mower is great for mulching, however, the mower packs the grass into the bag very tightly which allows more time to mow and less time emptying the bag. I highly recommend this mower and Read more …

    As promised, the mower starts right up with the turn of a key! It is wonderful. No sore shoulder yanking on pull cords. Why did I wait so long to buy this? It really is self-propelled. The only downside is if you aren’t careful you will pinch your finger when you pull up the lever to activate the self-propel. Yes, I learned that little safety tip the hard way. Extremely easy to put together. I was skeptical of the no-tools required statement. But Read more …

Thanks for this review and all the mower reviews on this site. It’s great to get a fully detailed rundown on the mowers rather than just a few words ripped off from Amazon and a heap of links like you find elsewhere. You seem to know your stuff when it comes to these tools so thanks again.
