Why You Need a Good Mulching Lawn Mower?

Natural Lawn Fertilizer

The mulching mower’s deck and blade design cause the grass clippings to be cut multiple times. The result is a fine mulch that is deposited on the surface of your lawn. This mulch breaks down quickly and forms a natural fertilizer to improve grass health.

Lawn Insulation

As your mower mulches the cuttings, you have a thin layer of mulch; your lawn can retain moisture by stopping water from evaporating in warm weather.

Lighter and Easier to Push

Grass catchers are great, yet once they fill, your machine gets heavier, and you need to keep emptying them. With a mulching mower, you avoid the need to empty and also find an area where to empty your cuttings. Such push mowers are easy to maneuver and won’t tip over.

Bagging Options

Mulching mowers are typically multi-functional, and with this, you can either go for the mulching option or bag your clippings. Conventional bagging models don’t offer a mulching feature. (Find the Best Lawn Mowers Snow Blower)

Best Mulching Lawn Mower Buying guide

When you purchase a mulching mower, there is less to look at than when buying riding lawn mowers, yet there are things to know.

Here’s a quick breakdown of things to be aware of when your checking mulching lawn mowers reviews.

Mulching Lawn Mowers Types

Push Mower: This type of mower is suitable for small yards of around 1/2 acre or smaller. They are affordable and come with motorized blades.

Self-Propelled Mower: You’ll find these typically have a rear or front-wheel drive, thus suitable for larger yards. As they are self-propelled, you walk behind and steer the mower. When mulching on slopes, a rear-wheel-drive mower is better as it pushes the rear wheels. Front-drive self-propelled mowers pull the front wheels and work better on flat lawns.

Riding Mowers: Such models are suited to multiple-acre gardens as they offer fatigue-free mowing.

Power Source

You tend to find two main power sources for mulching mowers, such as gas or electric.

Gas-powered: You will find these lawn mowers offer longer run-times and be more powerful than electric mowers. However, they need more maintenance.

Electric-powered: You’ll find these are with an extension cord or cordless and battery-powered. Which is easy & cleaner to operate than gas. Cordless models require at least 2 batteries, so if 1 battery starts to run out, it will use another. Corded models are limited by cord length.

Motor Power

The power of a mower determines how well it can cut grass without losing performance.

  • Corded: A corded mower provides 11 amps or 13 amps, and the higher the motor power, the better the performance.
  • Cordless: The motor power depends on battery voltage, and with a higher voltage, there is effective mulch mowing performance. Options you see are 40-volt or 56-volt.
  • Gas-Powered: Mowers with engine sizes delivering 5+ HP are preferred for proper grass cutting by a mulching mower.

Lawn Size

Mower power requirements depend on the lawn size where a push mower suits a small lawn of less than ½ acre, a self-propelled mower suits medium-sized up to 1 ½ acres, and above you’d use riding or stand-on mowers. If you need a self-propelled walk-behind mower with a larger lawn, look for a zero-turn mower.

Battery Life

Battery life will be vital on cordless models. Check the expected battery life of any lawn mower. Battery type is also a factor as some last longer than others.

Blade Width

The blade width of your mower is how wide the mower can cut. Choose wide blades that are suited to mulching rather than cutting. A mulching lawn mower has two cutting blades on each side, and the sizes you need are widths of 18 – 21 inches.

Cutting Height

The cutting height is vital for a healthy lawn, and your mower should have an adjustable range. Cutting height ranges are 1 inch – 2.5 inches and 0.5 inch – 1.5 inch.

Size & Weight

You will need to consider the mower’s size and the weight, as you can get fatigued by mowing grass on a large lawn with a push mower. Besides, you need to consider storage as a large mower will take up a considerable amount of space.

Noise

The power source will determine the noise of a lawn mower. Gas-powered mowers can be up to 100 decibels where you can reduce noise to half of this using an electric mower.

Warranty

Check the mulching lawn mower options that offer a decent warranty. Around 2-3 years are common, although some offer a warranty of 5 years.
