Frequently Asked Questions

Can I use my GreenWorks mower on hills and slopes?

Walk behind mower units should not be operated on slopes greater than 15 degrees. This is not a limitation of the unit, but rather to ensure safe footing for the user. When mowing on a hill remember to mow across rather than up and down.

What maintenance is required for my GreenWorks mower?

GreenWorks mower units require much less maintenance than a traditional gas unit. However, It will still require routine seasonal maintenance. After each use we advise emptying the bag (if bagging has been used), then check/clean off debris on the side discharge, rear slot, clean the underside of the deck with a cloth and wipe the unit down. If there is harder debris stuck to the underside, you may want to use a rubber deck scraper. Make sure to check the unit for loose nuts and bolts after use and secure if needed. Do not expose this unit to water. Check the blade for any damage/dullness and replace or sharpen as needed. Store the unit in a cool/covered and dry location such as garage or shed. If you have a battery-operated tool, batteries and chargers should be stored indoors. Please refer to your manual for more guidance on mower/battery maintenance and storage.

When should I cut my grass?

Here are some mowing tips that may be helpful:

Mow when grass is dry. Mow no more than 1/3 of the length of grass at a time.
Mow in the morning or late afternoon to reduce the heat stress on the newly cut grass.
Alternate mowing patterns each time you mow. As grass develops a grain based on your cutting direction it will lean towards the direction of your mowing path. Changing the pattern allows better vertical growth and helps to keep the cut neater.
Consider mulching. To mulch, remove the bag and insert the mulch plug into the rear of the unit. This will leave the clippings on the lawn allowing the nutrients and nitrogen contained within them to return to the soil and allow the remaining grass to recycle them (always discharge the mulch towards a previously cut area to prevent your mower from bogging down).
Leave grass a little higher in shaded areas. This keeps them healthy in relatively nutrient poor conditions.
Always keep in mind what conditions your variety of grass prefers. If your grass prefers cooler climates, reduce the frequency with which you mow and increase the cutting height of your mower during hot seasons to compensate for the reduced growth rate these varieties may experience in this type of weather.

Do I always need to use my self-propelled feature when operating a self-propelled mower?

No, you do not have to engage the self-propelled feature to operate a self-propelled unit. There are two separate motors. Familiarize yourself with the self-propelled feature and the cutting feature of your unit (instruction inside the manual). Once you understand these two features you can engage the blade without using the self-propelled feature.

Can my GreenWorks mower cut up pine cones, branches, twigs and other yard debris laying on my lawn?

GreenWorks mower are designed for grass, weeds and foliage. It would not be advisable to depend on the mower to mulch any other types of debris. Before operation please thoroughly inspect the area where the mower is to be used. Remove all stones, sticks, wire, toys, and other objects that could be tripped over or thrown by the blade. Thrown objects can cause serious personal injury.

Can I use my mower in wet conditions such as rain?

For safety reasons (which can be found inside your owner's manual under safety information) we advise not using the mower in wet conditions as unstable footing could cause operators to slip, causing a potential hazard.

* 60V X-RANGE line which features IPX4 weather-resistant construction and can be safely used in damp conditions. Be mindful of your footing during use in potentially slippery conditions.*

What does SmartCut™mean?

The SmartCut™ feature also considered a Power Save feature it is designed to maximize run time and battery life by automatically detecting the length of grass and adjusting its power or throttle up when needed. With this feature, the rotational speed of the blades will not always stay the same. They will spin faster automatically when you hit thicker grass.

Does my GreenWorks mower unit require gas or oil?

No, gas and oil are not required for the operation our units. GreenWorks mowers are either battery operated or corded (extension cord sold separately). This information can be seen on the product page of each tool and inside the owner’s manual.
