Greenworks 25302 Dual BladesDual Blades for better efficiency

The 10-inch dual metal blades of Greenworks 25302 G max 40V Twin Force 20 inch Cordless Lawn Mower is definitely an advantage as the performance of two shorter blades is better than the single large blade.

Power & performance

Power is great on this Greenworks 25302 G max 40V Twin Force 20 inch Cordless Lawn Mower for both bagging and mulching as it was supplied through batteries. It also provides powerful suction for mulching. But you should note that this power is not enough for wet leaves but it performs well for dry leaves. When you’re mowing with this mower, it gets easier through the tall, thick and even the scrubby grass. It produces a kind of spark when it comes closer to thicker grass so that it can cut more effectively and also saves the power while mowing the thinner sections of the lawn.

As this mower is easy to start, removing the bag is also easy, charges quickly and also placing the batteries in it is not at all a trouble. The height adjustments will be done from one handle for adjusting all the four wheels. But the only flaw here is while cutting the thicker or taller grass, the batteries will die faster as it uses more power.
