But for a medium or large size lawn, you need to have a riding mower to fulfill all your needs. So, keeping the size of the yard in mind is the first thing here!

For a Yard Less Than 3 Acres..!!
    For a yard having a size less than 3 acres, we recommend using a residential mower. Residential riding mowing starts from 11HP and goes up to 25HP.

For a Yard Larger Than 3 Acres..!!
    For a yard having a size less than 3 acres, You ust have a commercial mower. Therefore, 25HP to 37HP is powerful enough to meet all commercial mowing needs.Commercial mowers are explicitly built for such needs..!

Some people need a residential lawn mower to treat their small or medium-sized yards. And some are searching for a riding mower with commercial features for their vast properties.

So, you need to keep the size of the lawn in mind, whether you have a residential lawn to mow or a commercial property to manage.

Lawn Terrain

You must keep the terrain of your lawn in mind while buying a mower. Because the performance of riding mowers may vary among lawn types. A flat yard is easy to mow, and any riding mower performs well on it. But if you have hills and slopes in your yard, you might need to reconsider your choice.

For a Flat Lawn..!!
    The 11HP to 20HP range is good enough to mow a flat lawn. All riding mowers perform well in flat terrain. Look at the size of your yard and make a choice.

A smaller lawn may only need a push mower, but for a medium-size yard, zero turn or stand-on mower will be the go-to choice.

For an Un-Even / Hillside lawn..!!
    In harsh conditions, you need a powerful mower with a low center of gravity for hills and slopes. We recommend using a stand-on or zero turn mower in hillside needs with over 20HP.

Lawn Condition

Lawn condition includes the type of grass in the yard, whether it’s wet and slippery grass or it’s of dry and rough type. And how much dense the grass is affecting a lot while deciding How Much Horsepower Do I Need For a Riding Mower. So it’s necessary to notice the present condition of the lawn, the weather, and the density of the grass.

Therefore, we can summarize the lawn conditions as;

  • Wet and slippery.
  • Dry and rough.
  • Grass Density.

Wet and Slippery Grass

In the rainy season, you have to tackle wet and slippery grass that grows quickly during this time. The best way is with riding mowers equipped with sharp blades for better traction on hills as well as grooved wheels which give them improved handling in watery conditions like these!

For a Lawn with Wet and Slippery Grass..!!

    Thus, In riding mowers, we will recommend you the following conditions to mow grass in wet, damp, and rainy conditions;

    • Any riding mower with horsepower ranges from 19HP to 25HP with sharp blades to get fresh and even cut.
    • Riding mowers with grooved tires for a firm grip can be used to tackle the damp grass easily without slipping.

Note: Make sure to clean your mower after using it in damp conditions because it may invite bacteria and fungi to spoil your mower’s health.

Dry and Rough Grass

The struggle is real when it comes to cutting long grass. But don’t let your frustration get out of control! If you lift the deck off the dirt for just a few inches, then use this time as an opportunity to make sure everything gets cut evenly so there are no rough spots or rolls up with spindles in their blades – which can cause damage over extended periods.

Another tip to mow the dry, rough, and long grass is that when the height of the grass gets to 4 inches, it’s time to cut the grass off. Mow often, and don’t let the grass become long more than that. This may mean mowing twice a week or every four or five days when the grass is growing fastest in mid-spring.

Mulching blades are the most efficient way to cut your lawn when it’s at its peak during mid-spring. You should mow with a mulcher two or three times per week so that you can get rid of dry grass and have better results than before!

Grass Density

Another significant factor to consider is the Grass density. Because, Of the increase in growth of the grass, the grass starts becoming more dense and thick day by day.

To tackle this type of grass, you need to mow your lawn deeper and close to the soil. And it can only be done by using a powerful riding mower with a deck having a deep and wide cut.

It might be a residential lawn with deep, dense grass, and it can be at a commercial property, both types of places needed the same cutting width but with different horsepower engines.

Horsepower For a Highly-Dense Residential Lawn..!!
    You can mow the highly-dense residential lawn using sharp mulching blades under a deck up to 42 inches wide with cutting height positions from 6 to 13 with the deep cut ranging up to 4.5 inches, which is powered by a strong engine ranging up to 25HP.
For a Commercial Property Larger Than 3 acres with a Deep Density of Grass..!!
