How to Choose the Best Lawn Mower for Thick Grass

Best Lawn Mower for Thick Grass

Before you make your final selection of the best lawn mower for thick grass, there are several factors that you need to consider.

Type of Lawnmower

With different types of lawnmowers on the market, picking the best one for your needs is crucial.

Walk Mower- This mower is best if you want more versatility.

Self-Propelled Mower– If you plan to mow uphill, a self-propelled mower will be a great choice for you. For this model, you just need to steer it in the right direction without pushing it. This mower guarantees better traction and control when mowing thick grass on slopes or hills.

Front-Wheel Drive– Choose front-wheel drive if you want more maneuverability when mowing on level ground. It lets you reduce traction on the front wheels, allowing you access around obstacles and in corners.

Rear-Wheel Drive- This type of mower works best when mowing uphill or sidehill. It lets you push down on the handle when mowing uphill to prevent the front tires from losing traction.

All-Wheel Drive– It is also known as power reverse, all-wheel-drive mowers are designed for steep hills, sidehill, downhill, and any non-lawn areas.

Robot Mower- If you hate the task and hassle that comes with mowing, a robot mower may be ideal for you. These mowers can do the work for you in no time.

Power Options

When choosing the best lawn mower for thick grass, you need to select the power option based on your preference and needs. The lawnmower power options include:

Electric Lawn Mowers: Most lawnmower brands in the market are powered by electricity. Electric mowers are smaller in size and are best suited for small and medium-sized lawns. Due to their small size, they are easy to store and come at an affordable price.

Gas Lawn Mowers: If you have a large garden and are looking for a powerful mower, a gas-powered unit would be worth considering. Although more expensive than electric models, this lawnmower has more power and can cut thick grass faster. It also does an excellent job on rugged cutting conditions and can easily maneuver around large objects.

On the downside, gas lawn mowers require regular servicing and maintenance. What’s more, the price is high, and it varies with your power requirements.

Battery Lawnmowers: Other lawnmower models run on batteries. Battery lawnmowers are an ideal choice if you are seeking after mobility and long-range. Better yet, they can get the job done on both small and large lawns, depending on the battery size.

Type of Cutter or Blade

Lawnmowers for thick grass are equipped with different blades or cutters, and your option will be based on how you want your lawn to appear.

Cylinder Mowers: These lawnmowers are designed with cylindrical blades at the front of the mower. These blades rotate vertically and give a precise cut, making them best for manicuring flat lawns. However, they may not be perfect for overgrown or rugged terrain.

Rotary Mowers: Rotary mowers are equipped with a single blade that is located underneath and rotates horizontally. Unlike cylinder mowers, rotary mowers are very versatile and can cut rougher and longer grass.

Hover: These mowers are easier to push in unevenly-shaped surfaces since they hover over the ground. Although they are cheap and suitable for unevenly shaped lawns, they may not do very well for larger yards.


You need to consider when making your buying decision is what a mower does with the grass. Generally, mowers can mulch clippings, bag them, or discharge them.

Mulch clipping is repeatedly cutting grass clippings. Mulch mowers shred the grass clippings very finely before pushing the clippings back into the garden as mulch. The returned grass clippings are rich in nitrogen and help to improve grass health.

On the contrary, mowers that bag collect the clippings and give your lawn appearance. However, you will need to dump the clippings after mowing, which can be inconvenient for some people. The other option is side-discharge mowers, which come in handy when mowing non-lawn areas or areas with tall grass.

Some models are two-function, meaning that they mulch and bag, while others are three-function, meaning that they bag, mulch, and side discharge.

Cutting Width and Height

You should decide the cutting width of the mower based on your lawn size. The cutting width of a lawnmower is typically how wide it can cut. If you have a large lawn, opt for a mower with a larger cutting width to reduce the mowing time.

  • The perfect cutting width for a smaller lawn is 28-35 centimeters (up to 14”)
  • The perfect cutting width for a medium-sized lawn is 35-40 centimeters (14-16”)
  • Perfect cutting width for a larger lawn is 40 centimeters and more (16” and beyond)

Also, the mower’s cutting height is crucial to consider as this will determine how high the grass will be cut. You may also want to opt for lawn mowers with adjustable cutting heights so you can choose an excellent option for your situation.

Frequently Asked Questions

What type of lawnmower should I purchase?

When in the market for the best lawn mower, you should consider one that matches the size and type of your lawn. If your lawn is less than half an acre, then a walk-behind mower with a small deck may work best for you.
