Frequently Asked Questions
How often should I use the Sun Joe AJ805E?
You should typically dethatch your lawn once a year, preferably during the active growing season. This helps the grass recover quickly after the thatch removal process.
Is the Sun Joe AJ805E effective for moss?
Yes, this tool is highly effective at removing moss from your lawn. Using the scarifier setting helps lift moss out while cutting into the soil to improve drainage.
Do I need an extension cord?

Can I use it on wet grass?
It is strongly recommended to use this tool only on dry grass. Wet grass can clog the machine and may result in uneven thatch removal or damage to the lawn.
How do I change the dethatching tines?
Changing the tines is a straightforward process involving removing the side panel and securing the new cylinder in place. Always unplug the unit before performing any maintenance.
Does it require much assembly?
