Optimow® 50H Robotic Lawn Mower - 1/2 Acre High Cut

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.

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.

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.

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.

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.

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. *

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.

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.

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

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.
