Yes, this tool comes with two (2) 20V Power Share 5.0ah batteries and a dual-port charger for efficient charging.

The 40V Power Share™ tools are designed to work with two batteries and will not operate with just one battery installed. For optimum performance, both batteries should be of the same Amp-Hour (ah) rating and fully charged.

This lawn mower is not self-propelled, but is still agile and easy to work with.

The deck width is 20" and the cutting width is 19" to deliver great cutting efficiency

Yes, this lawn mower has a sturdy, metal cutting deck.

You can adjust the cutting height of this Lawn Mower to give you exactly the cut you want. Switch between multiple different cutting height positions with an easy-to-use single-lever adjustment.

The collection bag fill level can be checked by lifting the flap covering the opening. With over 1 bushel of fill capacity, emptying is easy and convenient.

This lawn mower can be used with or without the collection bag. If you’d rather not collect your clippings, you can use the rear discharge or mulching feature to feed the trimmings back into your yard to nourish it naturally.

Yes, this lawn mower has a side discharge outlet. With the lawn mower off and batteries removed, you can easily attach the direcitonal outlet to the side of the lawn mower with no tools required. This mower also comes with Nutricut® for premium mulching capability.

While your lawn mower is powerful enough to handle wet grass, we don’t recommend mowing wet grass. Wet grass can inhibit cutting performance, form clumps that interfere with the mulching action and/or reduce runtime. For best performance, wait until the grass dries before cutting.

Since this lawn mower is designed for easy, compact storage when not in use, it’s shipped to you in a similar configuration to save you on shipping. There is some minor assembly required, but will take less than 5 minutes and will not require any tools.

Changing blades on this lawn mower is easy! You’ll need protective hand gloves and a spanner wrench to remove the blade. For detailed instructions and illustrations, review the owner’s manual.

Storing the mower outside is not ideal and is not recommended. Worx lawn mowers fold into a compact shape to make storage in your garage or shed easy. For more information about folding down the mower for storage, review your owner’s manual.

Our lithium-ion (Li-Ion) tools and nickel-cadmium (Ni-Cad) tools are separate battery platforms and are not interchangeable. Li-Ion batteries offer our customers maintenance-free technology without the hassle of managing the memory effect inherent in Ni-Cad batteries.

While 20V Power Share allows you to share batteries between tools within the same voltage family, batteries should only be used with tools of a corresponding voltage. Use your 20V MAX Lithium battery with any 20V WORX tool.

If you decide your mower isn’t right for you, we offer a 30-day Money Back Guarantee from the date of receipt (less shipping and handling).  For more warranty information, click here
