Hart 40V Cordless Mower Vs Makita Self-Propelled Lawn Mower: What’s the Difference?

These two cordless mowers are comparable in size and performance, but key differences can help you determine which is right for you and your property. Check out their differences below. 

1. Motor types

HART lawn mower has a brushless motor, while the Makita has a brushed motor. 

Brushes in a brushed motor generate friction while rotating. The energy supplied to the motor is lost as heat, making brushed motors less efficient overall. A brushless motor is the better choice as it saves energy, preserves battery life and provides a long run time. Not to mention brushes wear out as you run your mower over time. This shortens the mower’s lifespan if replacements are unavailable.           

2. Mowing acreage on a single charge

The brushless motor and higher voltage of the HART 40 lawnmower make it more efficient. Though battery life varies with terrain and conditions when you mow, you can expect to cut up to ¾ acre with the HART mower versus ½ an acre with the Makita.

3. Buttons and levers 

Both motors feature ease-of-use adaptations and a push-button start. The HART uses a knob to adjust cutting height through a greater range of levels, while the Makita uses a lever to change the level of the mowing deck. 

4. Bagging

In addition to its 3-in-1 mulching, discharge, and bagging function, the HART mower has pass-through bagging. This makes it much easier to handle the mower bag so you can set up the mower and dispose of clippings without a mess.

5. Battery charge time

One of the downsides of electric power tools is the downtime while a drained battery is recharging. Manufacturers want to minimize this delay to ensure that your yard work gets done quickly. Makita batteries recharge in just 45 minutes, while HART batteries take an hour to be fully charged. 

The HART mower runs on a dual-active battery port for two batteries, while the Makita requires four batteries (sold separately) to deliver the full mowing duration. 

6. Warranties

Both mowers come with a decent manufacturer’s warranty. The Makita mower has a three-year limited warranty. HART mower offers five years warranty for the mower and three years for the battery.

7. Headlights

The HART cordless mower comes with integrated LED headlights. You’ll be glad of this feature if mowing dense brush or the light gets lower later in the day. 

What is HART 40V cordless mower?

The HART 40V Supercharge Brushless 21” self-propelled mower takes the sweat out of mowing your lawn. It has been designed with various features that simplify mowing and fold down easily for compact and convenient storage. 

Battery power with stamina 

This high-powered battery mower has the battery life to mow ¾ acre on a single charge! The mower is supplied with two high-quality 40V batteries so you can continue mowing when one battery is drained. 

Bag, mulch, or discharge easily 

With the HART 40V cordless mower, you can skip the hassle of raking or bagging your grass clippings. This mower features the latest 3-in-1 engineering to bag automatically, mulch, or discharge clippings however and whenever you want. 

Easy, intuitive handling 

Everything about this mower’s design makes getting the grass cut easier. The lightweight composite casing makes the mower easy to transport and fold down. A push-button start, a knob for cutting height adjustment, and fast folding handles for convenient storage make mowing less arduous. If you want to mow late in the day, the HART 40V cordless mower even has LED headlights, so the job always gets done.

Hart 40V Cordless Mower Vs Makita Self-Propelled Lawn Mower: Which One Wins? FAQs (Frequently Asked Questions) 

Do brushed motors have any benefit?

The main benefit of a brushed motor is that it is cheaper than newer, brushless motors. The cost-savings usually benefit the manufacturer, rather than the consumer, as the HART and Makita mowers are comparably priced. 

What is a self-propelled lawn mower?

Self-propelled lawnmowers drive themselves, saving you the effort of pushing them. An operator still needs to steer the mower but the mower automatically moves forward. There are front, rear, and all-wheel drive mowers that usually operate at speeds of up to 3 MPH.

What is mulching?

Mulching is a feature in lawnmowers that takes the generated grass clippings and deposits them as a thin layer on the cut lawn as the mower operates. The layer of clippings acts as a lawn fertilizer as they rapidly decompose and are absorbed by the growing grass. 

Can I use OEM Li-ion batteries with the Makita mower?

The Makita mower is not supplied with batteries. However, for the best performance of this mower (under warranty), the manufacturer recommends that only Makita-branded batteries and chargers are used. 

How long do cordless lawn mower batteries last before replacement?

You can expect cordless lawn mower batteries to last for up to 5 years before they require replacement. HART batteries are under warranty for 3 years.

Do cordless lawn mower batteries require any specific maintenance?

Lawn mower batteries require care and maintenance to maximize their capacity and longevity. Follow these simple tips:


  • To maintain its capacity, a lawn mower battery should be charged each month.
  • Don’t leave the batteries in the mower when it is not being used. 
  • Top up your batteries when you finish mowing. Avoid letting your batteries completely drain.
  • Remove the mower battery from the charger as soon as it is fully charged.
