GreenWorks 25302 20” Mower Review: Worth $ For 2 Blades?

The highest it will cut is 3.38”, which is quite a bit higher than the 2.75” maximum of many other push or walk behind mowers. If you’re a real mowing aficionado, there might be times when you want to cut your lawn at different heights, such as shorter so the sun can reach the soil or longer to retain moisture, but most of us are happy keeping it at one length all season long.

It’s also easy to adjust for different heights. Instead of having to adjust each wheel, all you need to do is move one lever into the desired position, and you’re ready to go. It will adjust for five different cutting heights of 1.38”, 1.88”, 2.38”, 2.88”, 3.38”, so you have quite a few choices for what might work best for you.

The Greenworks 20” does a great job at mulching leaves as long as you don’t let them build up too deep. So, if you have just a few inches of leaves, it should work fine, but if you have quite a pile, you’ll want to rake them down into a nice even layer before attacking them with the mulcher.

When compared with other models, this one is an incredibly quiet machine, and it’s a whole lot quieter than a gas powered model. In fact, it’s easy to have a conversation while its running and you’re standing right next to it.

One user in her review said the motor is actually silent and the only noise comes from the spinning blades and the grass being cut. She says it does make a whirring noise when going over gravel or twigs, but that’s it. She said the noise is a lot like that of a box fan you’d put in your window.

In user reviews, occasionally someone will complain that the bag is not catching all of the grass clippings. There are a couple of reasons this might happen. First, make sure the bag is not full. If it is, there are nowhere for the additional clippings to go, so it must be emptied to work properly.

Second, make sure the mulching plug is not in the mower. You should have either one or the other – either the bag or the mulching plug. If the mulching plug is in, the bag will not collect the clippings.

The short answer is… yes. This model folds down to about 14” – 16” for easy storage so you can slide it under shelves in your garage or into narrow spaces. As far as hanging it on a while, that’s doable as well as long as the bracket on which you hang it is attached to some sturdy wall studs.

As far as standing it up to store it – that’s not recommended as it would be very unstable in that position since the mowing deck is wider than the wheels.

If you live in Florida or even in a more desert-like climate, you might notice your lawn care tools get very dusty and dirty very quickly and can get gummed up. This raises the question as to whether this is a problem with the GreenWorks 25302 Twin Force.

People who have owned this machine for a few years say that yes, it does get dirty (like any lawnmower of course), but all you need to do is hose it off, and it’ll be like new again.
As for handle grass with sparse or sandy patches, it works very well. It even chops down tough weeds.

If your lawn is very thick or dense, this is a very valid concern. The answer is that it seems to do just fine. You just have to go a bit slower to allow the blades to cut. Going slower also means the batteries will run down faster than they would if you had a “normal” yard. Still, it does run up to 70 minutes on one charge, so as long as you don’t have a huge yard, you should be just fine.

One review by a man who has several thousand square feet of thick grass that hadn’t been cut in two months said he went a bit slower and made two passes – the first with the cut level set higher and had no problem getting it done.

It also helps if you wait until the grass is dry before cutting it – that way the blades work more efficiently, and it won’t take as long.

Really, they work just as well as a single blade unit. The blades are recessed above the bottom of the deck, so if you’re on uneven ground, the deck might be more likely to hit the ground, but as long as the blades can reach the grass, you’ll still be fine.

Many users have asked if you should store the batteries in the mower for extended periods of time (like throughout the winter). The answer is no, especially if you store the machine outside. While the battery compartments keep water out and the lithium ion batteries aren’t harmed by extreme heat or cold, it’s best to keep the protected and stored indoors if the lawnmower’s going to sit for a long time. Some people say the batteries have retained a full charge even after sitting for more than four months.

For seasonal use, the manufacturer recommends storing the batteries at half charge outside of the mowing unit if you’re storing them for more than four months. Look for two lights on the battery to see the amount of charge. You can even leave them on the charger as long as it is unplugged.

As far as the extended life of the batteries, they do come with a two year manufacturer’s warranty, so if they die prior to that time, you can get them replaced. Their life really depends on how much and how often they are used, but the manufacturer estimates they will last at least six years when purchased new.

One complaint about the batter is that in one review, the user had trouble getting the battery into the charger. For safety and to ensure a good connection, the battery snaps into place in the charging cradle, so you need to make sure it’s really in there so it will charge. When it’s seated correctly, you’ll hear a click and the charging light will go on. It takes about two and a half hours for the batteries to charge.

One user asked if this Greenworks model can be run from an extension cord, and the answer is no. It will only operate on the batteries. This is great if you don’t want a cord getting in the way. If you’re looking for a corded model, it’s best to buy a different machine.

The main safety feature is the incorporated right into the handle. In order to start it, you need to push the button, and then pull back on the handle. If you let the handle drop while mowing, it will shut off. There is no safety key (the previous model had one), as it’s not necessary with this updated feature.

There are things you can do to prevent accidental startup, though it’s hard to have one of those. However, if you have kids or others around that you don’t want starting the mower just for play, all you need to do is remove the batteries, and this can’t happen.

This model does not use ball bearings in the wheels. Instead, there is a sleeve, which seems just as dependable according to user reviews.
