When it comes to buying a lawn mower with side discharge, this isn’t the only feature to consider. If you happen to buy a push mower, the weight of the unit is important as you need to ensure it won’t cause you to tire easily.

Similarly, for the times you want to store your mower, the dimensions are important. If you have little storage space, a compact mower is better than a ride-on mower. Additional features like a collapsing handle are helpful too.

Finally, the maintenance of your mower is important. Look for a durable lawn mower that requires less maintenance than a mower that’s easy to wear down. We’ve considered all these features when evaluating our best mowers.

How to Buy the Best Lawn Mower with Side Discharge

Power Source

There are various types of mowers with different power sources, including electric, push mowers and petrol mowers. Petrol mowers tend to be louder than electric mowers.


With machinery that involves multiple moving pieces, there is always the risk that something might break before or during use. Looking for a mower with a warranty can help as it means the company may replace faulty parts or the entire mower. 


Depending on the frequency of use and the materials used, your mower may require more frequent maintenance. This includes sharpening the blades, clearing petrol lines and general repairs to the body of the mower.

Cutting width

The cutting width of your lawn mower is important, particularly for large gardens. A lawn mower with a smaller cutting deck will be impractical for larger gardens. In this case, a larger cutting width is important. 


Depending on the type of lawn mower you want, you need to ensure that the weight of the mower is not an issue. Push mowers should be lightweight to make it easier to move around your garden.


Finding a durable lawn mower which stands up to frequent use is the best option long term. It shouldn’t need frequent maintenance and will be a good investment in your garden care. 


Choosing a specific type of mower is important but can be difficult. Larger gardens may require a large ride-on mower while smaller gardens may be more suitable for a push or electric mower. 


Cost is always a factor to consider. You don’t want to go for a budget mower that does a poor job or falls apart after a few months. That being said, there are many quality side discharge mowers that are excellent value for money. The more expensive options tend to be a bit more powerful and include some additional bells and whistles. 

Frequently Asked Questions

What are some side discharge mower advantages?

Some advantages of side discharge mowers include effective cutting of wet grass, efficient mowing and non-stop mowing. When aimed correctly, the side discharge feature returns grass clippings to the garden, providing an effective, natural fertiliser. 

Side vs rear discharge mower: what is the difference?

With a rear discharge mower, you can take an efficient path through the garden. The grass clippings will be disposed of behind you, which makes for easy cleanup. Meanwhile, with side discharge mowers you need to cut grass against obstacles with the chute facing the other way.

Lawn mower side discharge vs mulching: is there a difference?

The primary difference between side discharge and mulching mowers is the type of blades used. Mulching mowers have curved blades which cut grass clippings into small pieces. Side discharge mowers cut grass clippings into uniform pieces and dispose of the grass through an opening.

What is a side discharge ride on a mower?

Ride-on mowers have a seat on which the user can sit while mowing their lawn. These mowers cut grass clippings into manageable pieces and suck the clippings into the machine. After which, the grass clippings are disposed of from a chute on the side of the mower. 

What type of grass is suitable for side discharge lawn mowers?

Lawn mowers with side discharge work well for wet or tall grass. They work effectively through the grass and help move the grass clippings back into the garden to be broken down as fertiliser.


Now that we have looked at our top picks of the best lawn mowers with side discharge, you should have a clearer idea of the options available.

Each of these lawn mowers has been compared based on factors including the weight and dimensions of the lawn mower to judge the manoeuvrability and ease of storage, and the power and cutting deck which will determine how long it takes to mow a particular lawn.
