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.

  • 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 pinecones, 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, 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.

  • Is the battery from my Greenworks mower interchangeable with the other units?
  • Greenworks offers a variety of different voltage lines for a wide range of individual residential needs. For example, we offer: 24v, 40v, 60v and 80v. Each voltage line has their own set of interchangeable tools and batteries but are not interchangeable across different voltage lines. To see compatible tools within each voltage line select shop by platform on our site. If you’re still unsure if your unit is compatible, please contact us at info@greenworkstools.com for further assistance. We’re happy to help

  • How do I start my mower unit?
  • For corded units, ensure you have the correct extension cord (reference the owner’s manual) and power from your outlet. If you’re using a battery unit, ensure the battery has a full/adequate charge. Make sure you are starting the unit in the following order, or it will not start: 1. Push down the safety switch button, while pressing the safety switch button with one hand, use your other hand to simultaneously pull the bale switch towards you. 2. Once the machine turns on you can let go of the safety button and continue to hold the bale (lever) handle. 3. The unit will only start when the safety button is pressed first, followed by the bale switch. If it is reversed the unit will not power on. For some of our EZ Fold™ units the start sequence will not affect the unit. Use the correct batteries according to the unit and ensure the batteries have adequate charge, you can either push the button first or pull up the handle. These models are not affected by the start order. However, please always refer to your owner’s manual for verification on the starting process as this would be the most accurate source of information.

  • What is the difference between auto-feed and bump and feed string trimmers?
  • Auto-feed string trimmers use centrifugal force to release trimmer line. Each time the unit is activated, the spinning of the trimmer head exerts a force that unlocks the trimmer spool, allowing line to be released. A spring-loaded mechanism relocks the line after approximately 0.25” of line has been release. Therefore, every trigger pull will release line. Bump feed/ bump and feed string trimmers work with a similar mechanism, but the spool lock is manual disengaged by the user by “bumping” the trimmer head on the ground while the unit is in use. This mechanism provides operators with more control over how much line is used.

  • What attachments are compatible with my string trimmer?
  • For attachment capable string trimmers, the following brands are compatible: Poulan Pro, Ryobi-Expand-it and Trimmer plus. If you are unsure if you have an attachment capable string trimmer unit, please contact us at 1-888-90-WORKS

  • Why does my trimmer line keep breaking during use?
  • Trimmer line will break off during use which is a normal occurrence. In harsher terrain or when used to edge, the string trimmer's line will break off more often as it makes contact with hard surfaces. To reduce line breakage here are some tips: • Keep the underside of the trimmer head/guard area clean of debris. • Ensure that the cutting blade is clean/clear, and the blade is exposed and shard enough to trim the line. This will also help to reduce excessive line breakage. • Avoid direct contact with hard surface areas when using the string trimmer. • In thicker, denser, and longer grass, you may want to go slower. Listen to the sound of the string trimmer, if it reduces speeds, or slows down too much, back away from the grass and start again at a slower pace.

  • Can I remove the guard from my string trimmer?
  • No, string trimmers should never be operated without a guard. The guard is a safety feature and helps reduce debris such as grass clippings from being picked up and flung towards the user. It also has a cutting bar on it to prevent line from overextending and breaking off at large lengths. Operating without a guard will cause the string trimmer to work harder than it must and will reduce the life span of the motor. It will also void the warranty.

  • Why does my line keep unraveling?
  • Line unraveling can be caused by winding the spool line the wrong way or simply not winding it tight enough. Please make sure you follow the guide inside your owner’s manual thoroughly as this process may take some time to correctly achieve.

  • What does reduced gear mean for my string trimmer?
  • A string trimmer that has a reduced gear motor does not directly drive the trimmer head. Instead, the motor drives a larger gear that is attached to the trimmer head. This reduces the speed of rotation but increases the torque. It allows a smaller, lighter motor to produce extra torque and perform tasks more efficiently, while ensuring that the unit is easy to maneuver.

  • Does my unit come with trimmer line?
  • Yes, all Greenworks string trimmers come with spool and line that has already been installed in your unit.

  • Can I use a thicker diameter line than what is recommended?
  • No, we do not advise using a thicker diameter line than what is advised in your owner’s manual. The use of a thicker line may result in over working the motor and could potentially damage the motor resulting in shorter life span of the unit. This will also void your warranty.

  • Can I buy replacement line locally?
  • Yes, you can use any generic brand of trimmer line to rewind your existing spool. Please refer to your owner’s manual to ensure you purchase the correct diameter of line for your unit.

  • Can I change the original trimmer head?
  • No, we do not offer this feature currently. However, we do offer attachment capable string trimmer units that can be used with a variety of different attachments from the following brands: Poulan Pro, Ryobi Expand-It and Trimmer Plus.
