Jonsered l4621 self-propelled gas lawn mower is known for its powerful engine, adjustable, and comfortable to hold handles and its self-propelled feature, among others. It is suitable for individuals who are looking forward to a long-lasting and easy to use mower. What is more, you get a swifter and effective mowing feature.

Jonsered is an excellent company that mainly deals with equipment such as chainsaws, blowers, hedge trimmers, and other outdoor equipment.

It was founded in 1833, and its products have earned a good reputation for their excellent performance and durability.

Jonsered l4621 Self-Propelled Gas Lawn Mower is easy-to-use and easy to own. The mower is highlighted by its full 21-inch cutting width and a sturdy front and rear wheels.

It also features a self-propelled system and can handle even the toughest terrain with ease.

Key Specifications of Jonsered L4621

There is a lot to talk about when it comes to the excellent specifications that this mower holds.

It is highlighted with a 7.75 ft. XTX engine, a premium and durable cutting deck for super bagging, mulching, and a side discharge 3 in 1 feature.

You also get variable speed control; this was, by far, a favorite feature for me. I would go for a faster speed whenever it reached the areas with lesser grass to attend to.

You can easily fold its handle. Do you have a small garage? Is it cramped and you are looking for a compact and easy to store lawn mower? Then, you might consider investing in this mower.

You can easily fold its handle and either store or carry it in both vertical and horizontal manner.

This helps to save on space, and in case it is stored in a vertical position, there is no spillage on oil or gas. More so, you can adjust the handle to a favorable height to achieve maximum comfort.

Unique Features

This lawnmower features some great features. There are a few of them that would elevate your interest in purchase. These features include:

Water Hose Connection

This is one feature that you will not find in most lawnmowers in the market.

Unlike many lawnmowers, which you have to turn them upside down to wash their deck of debris and grass, this one you only need to connect the water hose, and it does the rest of the job quickly.

This feature facilitates easy and effective cleaning of the entire deck. Through this, you are in a better position to keep your mower in good condition and make it last and free from any deck maintenance.

Powerful XT775 Engine

This is one feature worth mentioning; the machine is quite powerful. With the featured 173 cc engine, the oil always remains clean and at an adequate temperature.

It is quite impressive to know that you won’t have to change the oil frequently. In return, the engine gives you the power you need to mow your lawn within the least time possible.


Power, Design, and Durability


Most people, I included, would consider power as one significant aspect when buying a lawnmower.

It is through this feature that you know how effective the machine will serve you. Surprisingly, this mower is more potent than you think.

Apart from the powerful XTX series engine, Jonsered l4621 offers a relatively smooth-speed variable transmission. The vast and durable front and rear wheel help the mower to maneuver through any terrain with ease.

Its higher tunnel and a well-designed cutting deck offer premium cutting quality. You also get a bagging performance that holds as much debris as possible before you can unload it.


First and foremost, this lawnmower is compact and user friendly. Its handle is durable and offers different height adjustments to meet different needs. Once you complete the work, enjoy collapsing the handle for secure storage.

With its quick height adjustment feature, you get to choose between nine cutting heights that suit best your lawn.

Don’t worry about your landscape; whether it has bumps or hills, this lawnmower will come in handy any time.

The mower comes with a dual trigger control system. This feature helps you to operate either through both your hands or use it with your single hand.


We all want something that will keep us going for years. Before opting for this mower, I had previously suffered at the hands of many lawnmowers in the market that promise more than they deliver.

Buying a machine that will serve you for a few months then breaks down is disappointing.

Jonsered L4621 offers excellent maneuverability, and it can withstand some heavy use. It does have a 21-inch steel deck as well as sharp cutting blades that could go through the thickest of grass.

Cut Quality and Available Options

Apart from design, power, and performance, cut quality is another critical factor to consider before buying a lawnmower. This model does come with nine different cutting height options.

This means that you can choose from a one-inch close option, all the way to 4-inch selections.

You as well get adjustable speeds and dual trigger controls. All these features work hand in hand to give you the best and good cut quality for your lawn.

Some other available options for this lawnmower include;

  • Side discharge
  • Bagging
  • Mulching

High rear wheels and durable front wheels help you to maneuver with ease. This walk-behind mower helps reduce your efforts since you can choose to use a self-propelling feature.

There is no prior experience needed to handle this mower.

Switching between the three available cutting options is easy and straightforward. This feature gives you some good reasons to consider this mower.

Performance and Ease of Use

We already did talk about the performance and any mechanism highlighted by this product. Included is a powerful Kohler XTX engine that offers enough power as compared to most of its kind in the market.

The mower features an all-wheel-drive mechanism. Therefore it means that not even uneven terrain with severe conditions can be an issue to this mower. I noticed that it doesn’t scalp or lug on those grass thickets in your yard.

It’s a lawnmower, so cutting is a significant consideration. Jonsered l4621 handles nine different cutting positions. A minimum of less than 1 inch for the lowest grass cut and a maximum of 4 inches for increased heights.


Ease of maintenance, Repair, and Warranty

This lawnmower has little to no maintenance as long as you handle it with care and use it for the right purpose. It features an all-weather design, which means it is highly durable.

The fact that its deck height is easily adjustable and large enough, maintenance is reduced down to zero.

All that you need to do is connect your mower to the water hose connection every time you use it. Keeping it clean increases its service life. In case of damages or failure, repairs are readily available and cheap.


For this lawnmower, you get three years of free repair for any damage or built-in defects that occur during proper use.

The company has a high guarantee and confidence in their tools. They are, therefore, liable for the cost incurred in repairing the mower.

However, there are some things you must adhere to; visit your nearest authorized agent with proof of purchase. You can reach the customer service at 1.800.487.5951 for more inquiries.


Price of Jonsered L4621

In terms of budget, this mower is cost-effective. Comparing it with other walk-behind mowers, the Jonsered L4621 does bring more power and precision for your lawn work.


Who Should Buy It?

Various things accredit this lawnmower. It is one of a kind, easy to use, modest and a cost-effective mowing tool. It requires no prior knowledge or skill; therefore, anyone can use it.

Why We Like It

Let’s wrap this up with what we loved about it. Despite using gas, it is cost-effective. Its performance is excellent and can handle any terrain with ease. Its lightweight nature makes it even more convenient.

The power generated by its XTX engine is an added advantage.
