FAQs

How should I store and care for my Greenworks battery to ensure the best performance and longest lifespan?
We want you to get the most out of your tools, and that starts with understanding how to care for your battery. Proper storage and handling not only extend battery life but also ensure your tools are ready to perform when you need them most. A Quick Note on Lithium-Ion Battery Performance All Greenworks batteries use lithium-ion technology, which offers powerful, consistent performance without the memory effect found in older battery types. However, lithium-ion batteries are sensitive to temperature extremes—both heat and cold can affect performance and longevity. That’s why proper storage and care are essential for keeping your battery in peak condition. Best Practices for Battery Storage and Use: Store batteries indoors in a cool, dry location—away from direct sunlight, humidity, or extreme temperatures. This protects internal components and preserves performance. Only connect the battery to the charger when actively charging. When not in use, unplug the charger and keep the battery disconnected. If storing for an extended period, charge the battery fully before putting it away. Check the charge every couple of months. If it drops, recharge it before returning it to storage. This helps maintain battery health over time. Allow the battery to reach a safe operating temperature before use. For snow throwers and cold-weather operation, cold batteries may not power on. Let the battery warm to room temperature indoors before inserting it into the tool. Kindly note: Once the battery is at room temperature and installed, the current generated while the tool is running will help keep the battery warm. As long as the battery starts at room temperature, you should not experience issues even when working in cold outdoor conditions. For other tools/hot weather operation, if the battery has become hot from use or charging, allow it to cool before reinstalling. Indoor storage helps avoid performance issues related to both hot and cold environments and keeps your battery protected year-round.
Can I leave my battery in the charger after charging it?
The battery chargers do have auto cut offs to prevent it from over charging. However, we do advise customers to remove the battery from the charger after it has been fully charged and to also unplug the charger from the outlet, as this is good electrical safety practice to do so. This will also help to prevent false defect readings and allows the charger to reset itself each time it’s used to charge a battery.
Why do batteries cost so much more than the tool?
The battery is the most important component for a battery-operated unit. Please be assured we price our batteries with the cost of material, manufacturing, and current market pricing in mind. Batteries are the costliest items to manufacture and ship in any kit. Full kits including a tool, battery, and charger are priced affordably so that consumers can begin building that line of tools and move forward purchasing tool-only units. When you purchase batteries on their own, it is more notable the cost that they carry.
How do I store the battery? Can I leave the battery in the garage or shed?
When the battery is not in use, we suggest storing it indoors, in a cool dry area - away from direct sunlight. Leave the charger unplugged and the battery disconnected from the charger unless it needs charging. It is recommended to store the battery with a full charge, and if it is being stored for a period where no use is expected, to check on the charge every couple of months. If you notice the charge has dropped, we advise charging the battery back up to full before returning it to its safe storage place. Following these steps will ensure you receive the most out of the battery life.
My battery is stuck in my tool. How do I get it out?
60V/ 80V Products: To remove the battery, push and hold the battery release button. Then, pull the battery pack straight out. In some cases, if the springs underneath have gotten locked down you might have to give a small push to the top of the battery to re-engage them to help the battery pop up. The battery pack fits snugly into the product to prevent accidental dislodging while in use; it may require a strong pull to remove. Before use, be sure that the rails on the battery and product are free of debris that could cause the battery to get stuck. 24V/ 40V Products: To remove the battery, press the latch button on the battery pack down and hold. Pull the battery pack out of the handle. The battery pack fits snugly into the product to prevent accidental dislodging while in use; it may require a strong pull to remove. Before use, be sure that the rails on the battery and product are free of debris that could cause the battery to get stuck.
How do I check the charge on my battery?
Press the battery capacity indicator (BCI) button located at the end of the battery. The lights will illuminate according to the battery capacity level. Please note this switch does require a firm direct push using the tip of your finger. If the button is not being fully engaged, the lights will not activate. Please also be advised the lights only stay on for a few seconds and will automatically turn off. Another reason the lights will not power on is if the battery is completely depleted of power and needs to be charged.
Can I use any Greenworks battery in any Greenworks tool?
Our batteries are interchangeable with tools that are of the same voltage platform only. The difference between batteries of the same voltage is the ampere-hour (Ah) rating. The higher the ampere-hour (Ah) rating on the battery is the more run time it has to offer.
Are there certain tools that can’t accept all same voltage batteries?
There are a few exceptions. • Our 80V 20” snow thrower models 2600402 / 2605202 / 2601302 manufactured prior to September of 2017 can only use 2.0Ah or 2.5Ah battery models. • Our 60V 8.0Ah battery model 2957102 cannot be used in the following tools due to the height: dual-port lawnmowers, pressure washers, or the wet/dry vacuum.
Do all batteries of the same voltage use the same charger?
Yes, they do. Each product line has designated charger models that can charge all batteries in that voltage platform, no matter the Ah rating.
The charger indicates that my battery is fully charged but I was just using it and it depleted. Why isn’t it charging?
Putting a battery that was just in use onto the charger often results in a false full charge signal. Remove the battery from the charger and allow it to rest in a room temperature area for approximately 10-15 minutes before charging.
My charger is flashing red when I engage my battery. Why is this happening?
When the battery is inserted into the charger and the status LED blinks red, remove the battery from the charger for 1 minute, then reinsert. If the status LED blinks green, then the battery is properly charging. If the status LED is still blinking red, remove the battery and unplug the charger for 1 minute. After 1 minute, plug in the charger and reinsert the battery. If the status LED blinks green, then the battery is properly charging. If the status LED is still blinking red, then this likely indicates an issue with the battery or charger and should be taken care of either with our warranty team or by means of replacement.
My charger has a solid red light on it when I engage my battery. What is happening?
This typically indicates that the battery is at the wrong temperature to be charged. Allow the battery and charger to rest indoors at room temperature until they are no longer hot/cold and attempt charging again.
Are your chargers made for 220V or 120V outlets?
Greenworks chargers sold in the USA and Canada are designed for use on 120V outlets only.
What is the Tire pressure for CRT426?
Tire pressure should be checked and adjusted when the tires are cold. • Front Caster Wheels: 24 psi • Drive Wheels: 8 psi
Can I use my riding mower on hills?
Tire pressure should be checked and adjusted when the tires are cold. • Front Caster Wheels: 24 psi • Drive Wheels: 8 psi
How well does the riding mower mulch grass?
These mowers are excellent for mulching grass. For the best results, remove the side discharge chute and lower the deck to contain the grass, allowing it to be properly mulched.
Is a Zero-Turn mower easy to drive?
The ease of driving a zero-turn mower depends on the operator's experience. It may take some time to learn, as the mower uses two separate motors and handlebars instead of a traditional steering wheel. We recommend checking out our YouTube videos for helpful tutorials: Greenworks YouTube Channel.
What is the required maintenance for a Zero-Turn mower?
For regular maintenance such as blade cleaning and oil checking, please consult your instruction manual for guidance.
What riding mower deck size do I need?
• For yards up to 2 acres: 21” to 52” cutting width • For yards up to 1-3 acres: 52” to 54” cutting width • For yards up to 3-4 acres: 54” to 60” cutting width • For yards 4 acres and above: 60” or greater cutting width
Is the mower attachment capable of towing items?
These mowers are attachment-capable and can tow items like a yard sweeper or wheelbarrow. The maximum towing capacity is 350 lbs.
Can the mower cut in reverse?
The mower will only cut in reverse when the reverse button is pressed and held. This safety feature ensures safe operation while reversing.

DO NOT BUY

DONT BUY THIS MOWER!!! Blade motors die after just a few months and are very difficult to have replaced.

Nice Mower

When this mow was delivered the left blade was spinning backwards because it was not wired properly. It was a hassle finding the problem. Greenworks seems to have good products but is very weak on support.

Works great came with 1 dead battery!

The lawnmower itself works well so far however GreenWorks sent me 1 dead battery. This makes me question their Qaulity Checks. I will come back to update review if there are other issues discovered in the next few months.

My new favorite toy

My 80V zero turn mower with bagger has left a clean cut and no leaves. The bags filled faster than I expected but I'm getting better at anticipating how much is enough.

Bagging leaves.

Update after using bagger accessory for autumn leaf removal. Love it. Maybe not quite as thorough as a high powered leaf blower but so much easier and quieter and it gets the job done. The mower blades chop the leaves so some of the pieces fall down into the turf. I found that if there's a thick layer of leaves then running over the yard with the bagger chute removed and the mulch plate installed and then re-installing them for a second run creates a much finer mulch suitable for garden beds. It also means I only need to empty the bags twice instead of 6 times. The chute and mulch plate are easy to swap on and off with just a philips screwdriver and small pair of channel lock plyers. The two bags are easy to remove and empty. Just keep an eye on the transparent section of the chute and as soon as you see the leaves swirling around the bags are full. If the chute does get clogged it's very easy to unhook and clean out. Also the plastic hood over the bags doesn't really need to have the strap engaged every time as it stays fully closed even when the bags get over-filled. BTW it's probably much less effective if the leaves get wet so I'll mow them 4 or 5 times in the fall if rain is frequently in the forecast. I still use an electric leaf blower to get them away from trees and shrubs etc and for cleaning off the mower before putting it away.

Perfect balance of features for residential riding

Pro - 1. Zero-turn vs tractor: I think all ZT's will have trouble going sideways on hills. The front wheels have no grip and if the rear wheels loose a little traction it becomes unstable. This one goes straight up or down my 13.5 degree slope without a problem. Very controlled and lots of torque. And I have no problem mowing around trees and shrubs with 1 ft radius.2. Simple control panel: Nothing much to go wrong here. I don't want a fancy and fragile LCD display.3. Cargo bin: Very handy feature. I used it to haul 80# bags of cement to the back yard w/o needing to get out the garden cart.4. Construction and paint seat: Very solid steel and welds. Paint was perfect. Seat with armrests very comfortable and seems rugged enough. Springs are a bit stiff. Tilts forward for easy access to batteries.5. Costco: Return policy extra set of batteries discount and extended warrantee and pre-assembly service made it a too good to pass-up. And their delivery service was great! The guys dropped it off at the road and pushed it the 60 feet to my garage. And they went over the items to make sure everything was there. (I gave them a nice tip.) Note - I was unable to leave a review at Costco website due to error while setting up cookies.Con - 1. Takes a few days but running a ZT eventually becomes intuitive and really fun. You need to master the zero turn so one tire doesn't dig up the lawn but if you nudge one wheel into fwd and the other in rev it'll turn on a dime w/o issue. 2. Doesn't like going sideway on hills. 3. Drive wheels slip easily on damp grass. (Maybe adding some weight to the cargo bin will help?)4. Unlike a tractor mower you need to keep both hands on the controls constantly so maneuvering under my weeping beech tree is a challenge. 5. I had to buy 2 new tire pressure gauges. The rear tires are 8 psi so I got a 15 psi gauge. The front tires are 35 psi but the valve stem is hard to get to and you need one that has a sharp angle.Batteries: Lithium batteries are so costly to replace it was an issue for me but a free 2nd set eliminates that worry. I'll keep one set cool in my basement at 50% charge to extend their life and have them as a backup. (You can check the exact % charge level by inserting them in the mower one at a time. A set of 6 seem to all get drained at an equal rate.) With an 8 yr warrantee I might never need to buy new ones. 80 volt technology provides more power and it should be around for a long time. I'll also look into GW's other 80V equipment including their 120 volt inverter for when our power goes out. Removeable batteries make this possible. Plus you can store the mower outside without damaging them due to very cold or hot temps. And for large lawns you can swap them w/o waiting to recharge. A nice feature all around!Front Hitch: I bought a 2 hitch with a ring on it and am building a hoist to raise the front end. This will make it easier to remove blades for sharpening and for swapping in the high-lift blades that come with the bagger. (This is always an issue with riding mowers. Just look on youtube.)Bagger accessory: I got the bagger on sale from GW specifically for fall leaf cleanup. I think I was the last person in my town to still rake leaves (I hate loud leaf blowers). Last year I discovered mowing/bagging them was much easier. But my beloved 25 yr old Black&Decker lead-acid battery powered push mower wouldn't take that for long. Also blades were no longer available. I want to keep it going though as a backup. And the 1 bushel bag needs frequent emptying. The GW unit is 6 bushels and is very easy to empty. Hopefully it shreds them really fine so I can use for mulch on my shrubs.Me -70 and just retired in southwest CT. Bad knees so a riding mower was in the cards. Only 1/8 acre out of my half acre is lawn with lots of trees and shrubs to mow around and a 13.5 degree hill ~ 5 ft high next to driveway. I never mow when grass is wet. $4-5K is a big investment for me but the stars were aligned so it made sense to do it now. Looking at the GW chain saw hedge trimmer and pole saw. Hopefully GW will offer accessories for the front ETO hitch.

4 Mows then dead

Lasted 1 month and 5 days. Now I'm getting a pmu12 code and it says battery management module failure. Guess I'm returning to Costco.

Runs great cuts great but hard to put in reverse

Runs great cuts great but hard to put in reverse even with the seat all the way back. I have to push the handles hard into my chest to go in reverse.
