When purchasing the best lawn mower, you need to consider several things. There are lots of variant lawn mower are available in the market in 2020, also they are different types. It’s very hard to choose, which is the good one for you and provides you value for money. That’s why when you picked a lawn mower, I encourage you to measure your yard size and types and your budget.
Generally, the riding mower is a great option for larger yards. Whatever, If you have a large yard like 5 acres, it’s a good choice. There are a few things you need to consider before buying a perfect riding mower.
Engine performance and the feature are one of the major things for every mower. Generally, a rear engine riding mower has a 190cc to around 540cc powerful engine. On the other hand, the tractor engine has 400 to 750cc. The rear engine mower easily handles up to 1 to 3 acres of property.
The engine is powered by battery, gas, or petrol. For less noise and less carbon transmission, I encourage you to go with the electric riding mower.
Transmission is one of the most important features of riding a mower engine it’s a manual vs automatic transmission system. The manual transmission allows you to control the mower speed with a shift and clutch. Conversely, the auto transmissions systems are similar to cars, it speeds up when mower hit the grass and slow when you step on the brakes.
Without an excellent grip on wet grass and rough terrains riding mower can not handle the mowing job. Some tries features are including below;
These features will improve mower mowing performance in the toughest yards condition.
Choose the perfect cutting deck based on the property size. It saves you a lot of money. There several, cutting deck and yards size including below;
• 30- 40-inch deck – Suffice for ¾ to the 1-acre yard
• 42-52 inch deck – Ideal for up to 1 or 2-acre yard
• 50-54 inch deck – more enough to up to 2 to 3-acre yards
• 54-62 inch – Good picks for 5-acre lawns.
In my mowing experience and research, I just estimate the mowing time and deck value. If you want to finish your mowing job quickly then you need to choose the large deck.
A comfortable seat increases your mowing experience. There are several types of seating position available for riding mower also they have different types of features namely,
• Padded seats
• A high-back design and lumbar support
• Adjustable height settings
I research and find some advanced features that make your works a lot easier.
• Engine power – More engine power makes your works faster and smoother
• Engine torques – High engine torque offers a better cut in tall or thick grass
• Cruise control
• Cutting swath
• Variable speed model and the list go on.
Electric mowers are environment friendly and easy to use and maintain. Electric mowers reduce carbon transmission and much quieter.
There are two types of eclectic lawn mowers are available in the market.
The corded mowers are connecting the electric outlet and powered the mower. It has an unlimited running time. Conversely, the cordless mowers have a battery-powered engine. But they have a limited running time. They are not much powerful as the corded mower.
Usually, the cordless mower has around 30 to 60 minutes of runtime. If you think you need more running, I encourage you to buy a dual-battery cordless mower. The dual-battery powered cordless mower offers you at least 90 minutes of running time.
Usually, an electric mower has a small but powerful engine. The engine provides sufficient power to rotate the blades. The engine motor power around 10 amp to 16 amp. It’s enough to mow the small to medium-sized yard.
The electric mowers come with a compact and lightweight design. For their foldable handle design, you can easily save your garage storage. Also, some of them come with an adjustable handle. This types of handle allow you to quickly adjust the handle height and get rid of back pain in your mowing time.
Cordless mowers are powered by a battery. With proper maintenance and care, an electric mower lasts at least 8 – 10 years. But the battery will lose approximately 5% power per year. For that reason after 4 to 5 years, you need to change your mower battery. When you want to change your mower battery always read the mower manufacturer’s suggestion and picks a battery that compatible with your existing mower model.
The most cordless mower features 2Ah to 7Ah battery and they are capable of mowing for 30 to 60 minutes. Also, some of them have 30 to 45 minutes of running. Also, some of the cordless mowers offer dual batteries to increase mowing time.
The electric mower is safe to use. However, no matter what I say, some risk remains. Some safety features are including below;
• Never mow the wet grass
• Use rated cord (Corded)
• Make sure the battery is fully charged (Cordless)
• Always use a rated gauge extension cord
Robotic mowers are an alternative solution for traditional mowers. It is efficient for small lawns. There is a bunch of benefits lists of robotic mower have. But I think one of the most important benefits is you don’t do the work yourself, the robot mower doing everything that you want. It saves your time, required small maintenance.
Generally, when you looking for a mower, you should pick one that can handle the size of your lawn and also your lawn types. Robotic mowers are suitable for flat ideal small lawns. If your is hilly please choose a self-propelled mower.
Robotic mowers are powered by a battery. The battery life depends on the mower battery Ah. Because every manufacturer uses different types of Lithium-ion battery also they have different features. On average, we can expect the robotic mower battery life, around 1 hour. In terms of charging time, it will take approximately 40-70 minutes but it depends on the mower charging capability.
On average, a robotic mower cutting deck is around 22 inches – 40/44 inches. The average residential robotic lawn mower has a 22-inch floating deck and conversely, the commercial-grade robotic mower has a 40-45 inch cutting deck. As I mentioned, choosing a cutting deck almost depends on you. Wider cutting can save your time.
Robotic mowers are safe to use. It’s a battery-powered mower. There are a bunch of safety features robotic mower have namely;
• Auto shut off (Using Lift sensor, Tilt sensor)
• You can easily operate the lawn mower with your smartphone
• Automatic speed control
• Voice command options
• Working area setting
• Anti-thief features
• Safety sensor etc.
Reel mowers are the traditional mower. They come with a basic design and features. It dealing very properly with small lawns between ¼ acre to 0.5 acres. They are cheap, lightweight, and maintenance-free. Its lifetime at least up to 10 years with proper maintenance.
The majority of reel mowers have 14” to 18” cutting swath. For its push-type drive system, its cutting path is not wider than other types of mowers. Whatever they dealing with a few obstacles and suitable for small laws.
Like other types of mowers, you can adjust the blades cutting height on a push reel mower. Most of the reel mower has 1-inch to 3-inch cutting adjustment.
The push reel mowers are incredibly lightweight, easy to operate and maintain. There is no engine or battery power required to drive the mower. Simply grab the handle and push it forward and it will automatically spin the blades and start the mowing job.
The majority of reel mower has no grass management features. It is going forward and leaves the clipping grass behind your lawn. Clipping grass is good for the soil. However, most American homeowners don’t want to leave the mess behind. In this case, I recommend you purchase a grass bag or catcher.
Conversely, some of the push-reel mowers come with a grass bag of catcher. And also some of them come with a blower. The blower helps you to remove the clipping grass and saw a clean and nice-looking lawn.
When it comes to safety, it safer than the other mower. Why?
The answer is very simple. There is no electrical cord, no wires, and a battery. And also there is no engine and required very low maintenance.
The blades are the only dangerous things for a reel mower. Make sure that when you sharpening the blades, you wear safety gloves and glass, and also you can take the reel mower blade sharpening services.
Considering everything, the reel mower is safe, efficient and they are great for small flat laws.
Push or self-propelled drive system is the most common type of mower. For a push-type mower, you have to do the all work as the mower only spins the blades and cuts the grass using the motor power. And the push mower goes only as fast as you push it. Conversely, a self-propelled mower mechanically pushes the mower forward and you need only handle the mower. There are two types of self-propelled mowers are available.
Rear wheels drive system and front wheels drive system. Rear wheels drive system designed for hilly yards on the other hand front wheels drives system ideal for flat yards.
Both mowers come compact and lightweight and some of them feature adjustable or fold-able handles.
The self-propelled mower has a wider cutting deck and engine than a push-type mower.
The push mower has less power than the self-propelled mower. Both mowers are a great choice for small to medium-sized yards.
But if you want to purchase a premium mower, I encourage you to purchase a self-propelled mower. Its premium and reliable performance always give you clean and healthy lawns.
For commercial-grade features, a self-propelled mower is pricey than a push-type mower. But it features and performance offers you value for money. So if you want to invest around 200-400 USD then go with a self-propelled mower.
Before choosing a mower always see its motor power. With the motor horsepower, you can easily estimate how much time you need to mow your yard. A powerful motor spin the blades very fastly and offers you a premium cut quality and also it saves your time and tackles the toughest weed.
All types of mowers have a bunch of features. Buy 1st see which one is suitable for you. Above I mention every mower features and its positive and negative side.
Usually, mowers are powered by gas, electric, or battery power. The gas mower is powerful than the electric mower. But it, not our environment friendly. It makes a noise that’s is very annoying. Also, gas-powered mowers are made of fumes and it so much harmful for our earth.
On the other hand, electric lawn mowers are environment friendly. They are powered by electric outlets or batteries. They’re making less noise and provide zero-carbon.
When the motor power is combined with a sharpened mower blade, it tackles every toughest mowing job. The mower cutting path depends on the mower type. For riding a mower it is 30 to 60 inches. Conversely, the push of a self-propelled mower is 13 to 22 inches.
Every mower features lots of height changing option. Adjustable height offers to cut the grass at different levels. I think it very helpful to stripe a lawn.
The mower wheels provide traction better for easy maneuver. A durable wheel helps to easily maneuver and increase mower performance on the hilly or flat lawn. Whatever without better mobility you can not be done the mowing job perfectly.
When comes to grass management, majority, of mower manufacturer offer 3 in 1 ability. The 3-in-1 ability allows you to choose between mulching, rear bagging, and side discharge. And some of them have 2 in-1 ability. It depends. If you want to nice-looking then rear bagging is recommended and if your lawn needs nutrition then mulching is a good option.
Proper maintenance mower lasts at least 10 years. I including some great tips to maintain your mower namely;
• Change the oil at the end of each mowing seasons
• Before starting the mowing seasons sharpen the lawn mower blades
• Frequently check the lawn mower air filter. If it is dirty then change it or wash it
• Check the spark plug
• Always keep the mower clean
And the list goes on. But these are important tips to maintain a lawn mower.
• Before mowing the lawn always inspect the yards and make sure that there is no stone and other hard obstacles. These things damage your lawn mower blades.
• When you sharpen your mower blades always wear hand gloves and eye protectors and noise cancellation headphones.
• Kept the mower aways from your children
• Never mowing in the rainy season.
• Before cleaning, the mower always remove the spark plug
• Never pull the mower backward in your mowing time
• Before removing the grass catcher always turn off the mower and wait to stop the blades.
• Mow at only the dry grass and many more….!
Yes, you can.
With proper maintenance and care lawn mower lasts at least 8-10 years.
The simple answer is the rear wheels drive. The rear-wheel-drive gives you more traction than front wheels.
Approx. 3 to 4 years. Every battery-powered lawn mower every losing 5% battery life. For 3 to 4 years they losing around 15-20% battery life. That means after 3 to 4 years you need to change the battery.
Yes, you can. But mowing the wet grass with a corded lawn mower it’s is dangerous.
No, it’s is dangerous. Always mowing your yads in dry condition.
The majority of battery-powered lawn mower comes with a battery level indicator. You can easily the battery levels with it.
With proper maintenance and care riding mower 8 to 10 years.
1. Remove the battery
2. Clean youR mower
3. Add stabilizer fuel
4. And must storage your mower in a dry place.
For ½ or 1 acre, I recommend buying a riding mower. With a 30-40 inch, wider cutting swath saves your lots of energy and time.
Zero-turn mowers are expensive than riding mower. It tackles the very easily toughest terrains mowing condition. Considering everything it is worth.
Zero-turn mower uses versatile caster wheels that allow to quickly maneuver. For its versatile wheel, it can run into the hills and you can start your mowing job.
Long story short zero turn mower go faster but slower in mowing. The zero-turn mower offers clean-cut 5 mph and top speed 10 mph.
On the other hand lawn tractor mow at 4 mph and top speed 7 mph.
Yes, you can mow yards in rainy yards. But we do not recommend it.
Generally, robot mowers have excellent mulching capability. They do not collect the grass.
By comparison of other types of mower, robot lawn mowers are safe even they have quick-moving sharpening blades.
With proper maintenance and care, we expect robot mower to last at least 10 years.
