powerful,well-engineered, reliable, and affordable mower

If you are looking for a walk-behind mower that runs on gasoline and can perform on all types of terrains, there is no better option than Lawn-Boy 17734. This is a powerful,well-engineered, reliable, and affordable mower perfect for smaller lawns or yards.

Performance and Cut Quality

Lawn-Boy 17734 is powered with a Kohler® XTX OHV engine that gives a new definition to lawn care. Equipped with commercial-grade features, this lawn mower performs excellently in all kinds of yards or lawns. When I used it for the first time, I instantly realized that it is reliable, stable, and will serve me for years. Like other gas-powered mowers, it’s engine does not produce much sound. So, you no longer need to worry about your mower disturbing your neighbors.

Coming to the cut quality, it is equipped with a tri-cut cutting system which helps in cutting the grass efficiently and evenly.With this mower, you can adjust the height of cut to either 1.25 inches or 3.75 inches. One thing I want to suggest is not to use this mower on wet grass. If you do so, things under the deck might get clumpy and in the worst case, the engine may die. It works effectively on the flat, hilly, and uneven terrains.

Ease of Use

In this price range, I haven’t seen any gas-powered mower so easy to use. Lawn-Boy 17734 is crafted by keeping you (customers) in mind and its compact design and features like electric start prove it. Yes, you just need to turn a key and it will be ready for mowing. This mower is so easy to use that even a six feet height person can easily mow with it without bending forward. Its 21-inch cutting deck allows you to cut quickly. The combination of bigger rear wheels and smaller front wheels offers better stability and allows it to perform greatly on uneven terrains also.Moreover,it weighs only72 pounds (nothing much for a gas-powered mower) which implies you will not face any difficulty in moving it in your lawn or backyard.

Special Features

The first special feature it has is the robust, reliable and quick to start 149ccKohler® XTX OHV engine. You don’t need to change its oil but this doesn’t mean you should avoid checking the oil level prior to each use. It is also equipped with Smart-Choke technology that automatically adjusts the amount of fuel required to start its engine. Another special feature of this mower is the Lawn-Boy Engineered Tri-Cut System that provides amazing mulching capabilities and excellent cut quality. Bigger rear wheels (of 8 inches) and bigger bag (2 bushels) are other special features of Lawn-Boy 17734. I have seen many gas-powered mowers in the market but none pleases me, some are priced high and some don’t have features. This is a unique combination of features and affordable price. I also found that side-discharge is given as an optional feature in it.


Lawn-Boy 17734 is designed to enhance your mowing experience. Measuring 40.5 x 22.3 x 37.7 inches, this is one of the most compact gas-powered mowers I have come across till now. After mowing you can easily place it in a corner of your garage.Despite steel deck, it weighs just 72 pounds.Unlike traditional red-colored mowers, this one is available in eye-pleasing green color. This mower’s rear wheels of 8 inches and front wheels of 7 inches are also an addition to its great looks. The handle is adjustable (2 positions) which means whatever be the height of a person, using it is not a problem. Once you take it out of the box, it takes around 3 minutes to attach the handle, tighten it with bolts, pour the oil. However, charging the battery for the electric start takes time.Let me tell you the design of Lawn-Boy 17734 makes it a perfect gas-powered mower for lawns or yards up to ½ acres but remember,it is not designed for cutting bushes.

Cost Effectiveness

Since it is the CARB compliant and electric start model from Lawn-Boy, it costs a few dollars extra. Frankly speaking, it won’t help you save as much money as an electric mower but when you compare it with other gas-powered mowers, you will find this one is the most cost-effective. Also, you won’t find any mower with electric start, self-propulsion, and other features priced at just $339.99. There are two more cost-effective features of Lawn-Boy 17734; first is the mulching option providing free fertilization and second is the way grass is sliced – it prevents you from purchasing a Weed Wacker. Moreover, it being a low-maintenance mower helps you save big in the long run.

Grass Collection and Discharge

When you don’t want to collect the clippings in its bag but mulch the mowed grass, you can attach the chute that makes side-discharge quite easy. It can be easily attached but the sad news is that It doesn’t come with this mower, you have to order it separately (If you want to get it for free, register on the website of Lawn-Boy). It comes with a bag to collect the clipped grass. The bag is of a bigger size which means you don’t have to stop again and again to empty it. However, a cover over grass catcher is missing which causes a gap between the bag and mower. A simple way is to make a cover on your own and hide this gap. This will also cut down debris and dust that you come across while walking behind this mower.


When it comes to manoeuvrability, Lawn-Boy 17734 is one of the best walk-behind mowers. Whether you use it on a flat surface, hilly region, slope or uneven terrain, this mower will move efficiently.You can easily adjust its wheels because it has one lever in the front and another one in the back. If the surface you are mowing demands all wheels at a similar height, you can easily bring all wheels in alignment. The rear-wheel-drive arrangement provides superior traction in different cutting conditions. I will advise not to use it on extremely steep slopes; after all this model is made for residential use only. The weight of 72 pounds is also the reason behind its smooth movement in a yard.


For maintenance of this mower, you don’t need to worry much. The biggest thing you have to do is check its oil before every use and I think this is a very normal thing with gas-powered mowers. I suggest that after every use, you should clean the debris and grass clippings below the deck. After using it for every 25 hours, you should also check the air cleaner regularly for loose, damaged or dirty parts. If necessary, make a replacement. The company suggests to replace the air cleaner and spark plug after every 100 hours. I agree with them because all this will increase the life of your mower. At last, I want you to purchase the cover of Lawn-Boy 17734 separately from the market. The cover will guard the whole unit (inclusive of the rear bag). You can even store the covered mower in an open area fearlessly, without any problem.
