1. Honda HRR216K9VKA Self-Propelled Gas Mower

Honda HRR216K9VKA Variable Speed Self Propelled Gas MowerHonda engines have earned themselves a good name especially in the motorcycle industry. I was torn between the Honda HRR216K9VKA and the Greenworks – 22502 as they’re both equally good self-propelled mowers.

I settled for this model as it was easy to start every single time I had to clear debris off its path. The typical self-propelled mowers are bulky and cause damage to the lawn when they turn.

The Fiskar 18 cuts 18 inches of width so quietly that you’ll barely noise when it’s own. Combine quiet mowing, eco-friendly and a comfortable handle and you will have created this model.

Lawnmower for tall grass buying guide

1. The mower’s power

This will be dependent on how frequent your lawn needs mowing, the size of your lawn and the type of grass that grows there. If your property is set on a generally hilly area, you’ll need a mower with a powerful motor.

Even though larger capacity engines aren’t economical on gas, you won’t be able to mow tall thick grass with a 120-cc mower.

2. Bagging

Contemporary mowers collect clippings in their bagging compartments instead of dropping them. Say goodbye to raking. The grass is fast decaying and clippings will decompose in under two months However, most people opt for lawn mowers with bagging as they leave a better curb appeal.

3. Simplicity

The best mowers are simple and easy to use. In this list, I’ve only showcased easy to use mowers that I enjoyed using. You should be able to interact with the controls even without going through the manufacturer’s manual. The power transmission should be efficient too making the mower economical on energy.

Frequently asked Questions

Can you use a lawn mower on long grass?

Yes, of course. All you need is make the right adjustments while you mow. If the grass is too long, you raise your mowing height and gradually reduce it to reach the recommended height. However, not all lawn mowers can be used on long grass. Zero-Turn Riding mowers and Push Reel mowers aren’t designed to cut long grasses; however, they can cut it if you have extra energy and time.

What is the best length to mow the grass?

The optimal height for a cool-season grass generally is about 2 1/2 inches. And at each mowing, you should only be removing about the top 1/3 of the grass blade. Consequently, a good time to mow lawns is when your grass is about 3 2/3 inches high.

Will mowing wet grass ruin lawn mower?

Yes, mowing wet grass can ruin lawn mower two or more ways. Wet grass does not cut cleanly. That results in more extensive clippings and clump together. What’s more, the clumping can block the mower deck, reduce mower performance, and lead to other issues.

If you’re using an electric more, you risk getting yourself electrocuted. Since the wet lawn might have waterlogged areas, it’s relatively easy to damage your electric or battery-operated mower. There is also the risk of contaminating the fuel of a gas-operated mower, especially if you do not use a fuel stabilizer.

How do you clean electric lawn mowers?

Electrical mowers are cleaned using the same procedure as gas mowers. However, special care should be taken to ensure that moisture doesn’t get to the circuit board. It may damage the mower’s delicate internal components.

Using a clean soft cloth, wipe off grasses and other organic matter from the blades. Sharpen the blades at the beginning of each cutting season. Oil all other moving mechanical components

What do you do when the mower won’t start?

Worn out spark plugs and filled carburetors are often the biggest culprits when your mower won’t start. Start by ensuring that the lawn mower has adequate fuel levels. Fuels break down when left unattended for over a month.

Drain and dispose the stale fuel from the mower and replace it with fresh gas. In addition to extending the life span of your mower, this will help stabilize the engine too.

A carburetor is responsible for cleaning air before it gets to the engine. It’s a lawn mowers equivalent of an air filter. When the carburetor is clogged up, the lawn mower wont start. Get commercial carburetor cleaner from a local store.

Coming in convenient pressurized cans, this solvent dissolves twigs and mud that finds its way to the carburetor’s filter.

What causes the engine to smoke excessively?

When the smoke turns from black to blue or white, then the engine is burning oil. Have it serviced by a qualified mechanic. When there’s dark smoke, the carburetor is clogged and there’s incomplete combustion if fuel. Clean the fuel filter and carburetor.

  • Great post. I am really into the all electric mowers, and battery powered mowers. I personally own a RYOBI, but the Greenworks, EGO, and SunJoe mowers are great.
