Five Tips for Buying a Mower
Choosing a lawn mower is a matter of sifting through a bewildering array of types, power ratings, and fuel sources. Let’s break it down a little to make the process easier.

What types of walk-behind mowers are there?
There are four basic choices: push reel, electric, cordless, and gas. All have strengths and weaknesses.

• Push reel mowers are powered by you. They’re quiet, they don’t need cords or recharging, and they don’t pollute. But on large lawns, you might not want the workout you get when using a push reel mower. They also tend to be less effective on grass taller than two inches.
• Electric mowers need to be plugged into an outlet to power them, which means you’re constrained by the location of power outlets, the length of your power cord, and any obstacles that may snag the cord. If you have a small yard but don’t want the forced exercise of using a push reel mower, an electric mower may be for you.
• Cordless mowers are powered by a rechargeable battery. You don’t have to deal with the hassles of keeping a cord plugged in, but battery life becomes a constraint. Depending on the battery capacity, the size of your yard, and the height of your grass, you may not be able to complete your mowing job on one charge.
• Gas mowers offer the most power, which is best if you’ll be mowing tall, dense grass or if your yard is larger than 2,000 square feet. But you will have to keep gas and oil on hand as well as keep the engine serviced.

What do all the power measurements mean?
All that matters to you is whether the lawn mower’s blade will spin fast enough to cut your grass. Unfortunately, mowers are rated in far more technical terms.

For gas mowers, there are three power measurements you may see:

• horsepower (hp) refers to the amount of power the engine can produce;
• torque is the amount of horsepower that is transferred to the blade;
• cc (cubic centimeters) is another to measure an engine’s power based on the displacement volume of its cylinders.

There also are two types of engines: two-stroke (also referred to as two-cycle) and four-stroke (or four-cycle). Conventional wisdom is that two-stroke engines offer more power but also more pollution.
For electric and cordless mowers, power often is measured in volts, amps, or watts. To satisfy your inner techie, here’s how to calculate the horsepower:
1. Multiply the volts by the amps to get the wattage.
2. Divide the wattage by 746 to get the horsepower.

More horsepower doesn’t always mean more cutting power. That’s why, starting in 2007, most lawnmower manufacturers began rating walk-behind lawn mowers in torque power or cc’s--not horsepower. If torque isn’t available for a gas mower, higher cc figures usually mean higher torque (and more fuel used per stroke, incidentally).

However, you don’t want to buy a mower based on the power measurement alone. Make sure it has the features, warranty, and quality of reviews you’re seeking.

What features should I look for?

• Cutting Deck
  This refers to the blade housing. The wider the cutting deck, the fewer passes it will take to mow a given area. However, consider how many obstacles there are in your yard. The wider the deck, the tougher it may be to fit the mower into tight spaces.
  

• Mulching and Bagging
  Want to collect your clippings? Choose a mower with a rear- or side-bag option. Want to leave clippings on the lawn as fertilizer? Get a mower that mulches. A "3-in-1" mower will mulch, bag, or side-discharge.
  

• Wheels
  Larger wheels mean easier handling, especially over rough terrain. If you can, go with at least 7-inch-diameter wheels in the rear--larger if your yard is hilly or uneven. Some higher-end mowers have front wheels on casters, which gives you an extremely tight turning radius.
  

• Height Adjustment
  Most mowers allow you to adjust the distance between the blade and the ground. Think about how much range you really need.
  

• Safety
  Many newer rotary machines are available with a lever or bar that must be depressed to keep the mower running (some models include a handy blade-brake that lets you release the lever without killing the engine).
  Also, look for models with a rubber flap at the back to block objects thrown from the blades. You should always wear safety goggles when mowing and follow all the manufacturer’s safety instructions regardless of the mower you’re using.
  

• Batteries
  If you’re buying a cordless mower, think about how long it will run on a single charge. Most batteries take several hours to recharge, so you want to make sure it’s going to get the job done before it runs out of juice. As a rule of thumb, a typical 24-volt mower will run up to one-and-a-half hours and cut up to a third of an acre; a 36-volt mower will go for three hours and cut up to a half an acre.
  

• Cord holder
  A cord holder is useful for keeping the cord of your electric mower out of the way when you make turns.
  

• Starters
  Gas mowers are available either with recoil (pull-cord) or electric starters. Newer recoil motors start much quicker than those you remember from summers past. However, go with electric if you can afford it: your mower will start with the push of a button or the turn of a key.
  

• Self-propelled or push?
  A self-propelled mower moves forward without you having to push it. All you have to do is steer. If you have a relatively flat lawn, save a few bucks by skipping this feature. However, if your landscape has a slope or an irregular contour, a self-propelled model may be the best choice. Rear-wheel drive tends to offer better traction.
  

• Variable Speed
  If you want a self-propelled mower, look for models with variable speed. This feature allows you to make adjustments within a continuous range so you can find the exact speed that’s comfortable for you.

What servicing and maintenance is necessary?
Always buy a mower that comes with a manufacturer’s warranty and follow the manufacturer’s routine maintenance instructions for

• Cleaning the mower after usage;
• Keeping the blade sharp;
• Keeping the engine tuned up (gas mowers); and
• Keeping the battery charged (cordless mowers).

While Amazon.com does not accept returns on gas-powered mowers, the manufacturer’s Website or product manual will list the nearest service center.

What does CARB-compliant mean?
CARB is an acronym for California Air Resource Board, whose stringent air-quality standards have been adopted by many states. If your state requires compliance for gas mowers, confirm that your model is CARB-certified before you buy. While CARB-compliant mowers run cleaner than noncompliant models, they still emit pollutants. If you want to go green, an electric or push reel mower is the way to go.

Amazon.com Product Review
Bravo to Black & Decker for two great innovations on this electric mower. First, the flip-over handle! You get to the end of a pass, flip the handle and head back the other way in an instant. Next, users will especially appreciate the one-touch lever that raises and lowers all four wheels at once from 1 inch to 3-1/2 inches, saving the trouble of adjusting each wheel’s height. It’s about time. In addition, the electric 12-amp motor means hassle-free starting, no gas/oil mixes, no fumes, less noise, and no battery to charge. The cushioned handle adjusts for the user’s height, another nice touch not available on most mowers. It mulches beautifully, but if you prefer, you can purchase a side bag. Electric mowers have their naysayers, but if you’re in the market for one, you can’t beat this.--Kris Jensen-Van Heste

Customer Reviews

heavier than I thought, but still very useable
buying on the internet is always scary. So far, I've relyied on other peoples review on Amazon. This time, I feel like I must to help a few people out.

First, my co-workers were skeptical about an electric mower, but I've had the experience in the past.

Here are some of the benefits:
- you can look under your mower by flipping it over and not worry about gaz or oil leaks.
- grass is cut from end to end of a yard easier with the flip handle than those that don't. (that should include all gaz mowers) Instead of closing in on the middle of your lawn, you start on one end and finish at the other end. (I like it)
- this mower doesn't retain anything underneath. I didn't know that some mowers would do that. From my previous experiences, you had to clean up the mower every couple of use.
- height adjustment is super simple.
- electronic brake. If you release the power (bar!), the blade stops in a micro second. This is great for safety.
- no smells of any sort (except first few minutes being a new electrical product)

I wouldn't trade it, and my yard is not small.

Much better than a gasoline.mower.
The MM675 Lawn Hog is my first electric lawn mower. All comparisons are therefore with my previous gasoline lawn mowers. My lawn is less than 3500 square feet. It was very easy to assemble. The first thing after assembling was a very simple pull of one lever to adjust cutting height. I followed the instructions for starting to mow closest to the outlet while leaving enough slack cord to extend to the furthest distance to be mowed to. Attention had to be paid to the cord, so as not to run the mower over it. Unlike my gasoline mower it started quietly and easily at the simple pull of a lever. I started in the first lane and upon reaching the end of this lane I easily maneuved to the second lane while flipping the handle. I proceeded to complete the entire lawn in this manner. Because it was so easy to start the mower and switch to the next lane, I was not as tired when I finished as when I used a gasoline mower. The trade off is paying attention to an extension cord vs. easy start, no gasoline, no oil, low noise and less stress on my body. Only because I have not had it that long did I fail to give it five stars. I don't know how much maintenance it will require nor how much power it will have to mow heavily growing grass later in the season. But, because of previous pleasent experiences with other Black and Decker products I expect both of these questions to be answered positively and this to be a five star product.

great lawnmower, but not this model
You do not want this model - you want the Black and Decker MM575. Here's why: The "flip handle" on the MM675 is a disaster for two reasons. First, no electric lawnmower is powerful enough to 'mulch' - it will just bog down (unless you cut your grass every other day, and you live where it never rains). So you need to be using it in the 'discharge' mode. If you try to use the 'flip' handle at the end of each pass, the discharged grass always goes in the same direction, and the mower will again bog down as it tries to recut ever more grass with each pass. (Take a minute to visualize the geometry and you'll see what I mean). Secondly and even more important, to make the handle 'flip', it attaches to the mower in the MIDDLE of the mower instead of near the rear wheels. This is critical because it means the force of your pushing goes half to pushing the mower forward, and half to pushing the wheels into the ground ! I've cut my grass with an electric mower for over 20 years, and my arms were screaming after only 10 minutes of pushing the MM675. I traded it in for the MM575 (no 'flip' handle: it attaches next to the rear wheels, and you pivot the whole mower at the end of each row, just like with a gas mower) and I can mow for 45 minutes to an hour without arm fatigue.

On the plus side, both these models are well balanced (no vibration), relatively quiet, and cut great. Best of all, the underside is one molded plastic piece - no nooks or crannies for cut grass to build up. My old mower had all sorts of screwheads and spots where different pieces of metal adjoined that jammed up with cut grass. I would spend 5 minutes with a putty knife scraping the underside of the mower clean after each use. After cutting with this mower the first time, I flipped it over to scrape out the grass, and it was spotless ! B + D, wake up and market that great feature !!!
