40V HP Brushless Carbon Fiber Attachment Capable String Trimmer with 4.0 Ah Battery & Charger
40V HP Brushless Carbon Fiber Attachment Capable String Trimmer with 4.0 Ah Battery & Charger is rated 4.8 out of 5 by 121.
Rated 5 out of 5 by from Excellent overall tool Just purchased this trimmer because my older Ryobi finally died. (fell off the bench and tore the power cord out along with breaking the motor housing). was very pleased with the string trimmer portion of the new unit, the fact that I don't have to take the string reel apart in order to replace the trimming string is a great improvement. I think the best part of this new trimmer is the speed crank for replacing the trimmer string. Why didn't someone come up with this sooner? Probably the best thing about buying this trimmer is the fact that the attachments (tiller, edger and nlower) will work with the new trimmer. Great bonus.

Rated 5 out of 5 by from Excellent replacement for corded electric unit I previously had a corded electric trimmer with additional Ryobi attachments. The 40V HP Brushless model appeared to have equivalent power and plenty of battery lifetime to use my existing edger and blower attachments. The power available was fine - plenty of power even for the edger and no problem with battery life. The quarter-turn attachment lock works better than the previous multi-turn lock screw. Older attachments have the lock button to the right which is occasionally obscured by the position of the lock screw. Because it's a new product, some of the manual details hadn't been updated: such as that it supports 0.95" line now instead of 0.80.

Rated 5 out of 5 by from I can hear and I don't smell! I recently made a decision to eliminate all the gasoline powered yard devices in my garage that I could. Currently the size of my prohibits the elimination of a yard tractor, but when the right vehicle comes along, it will go. I'm sorry I didn't purchase this sooner. Without question, it cuts better, faster and is easier to handle than my previous gas powered unit. There is simply no comparison. Add the 40v battery power and I been able to edge the entire front and backyards and all the shrubbery 3 times without exhausting the battery. Given the size of my yard, that's amazing. And ... my ears aren't ringing and I don't smell like a gas station. Buy one - you won't be disappointed!

Rated 5 out of 5 by from Good Bye Gas I bought the 18v and if you live in the city great choice. The new 40v takes the place of the gas power weedears. This weed eater is light weight even with the 40v. Would like to see it with just a little less weight Plus.. This weed eater can be used around flower beds own low speed then back to high speed to cut just about anything. You can use string or the orange cutters in thick or tall grass. The string feed works great so far and easy to reload replacement string. Is there a way the shaft can be adjustable for shorter people. If it could slide in and out 4 to 6 inches for better control. The wife enjoys taking care of the yard work.

Rated 5 out of 5 by from Excellent trimmer! Bought this trimmer months ago. It’s works really great! Will never go back to a gas powered trimmer again. My only complaint is the line feed doesn’t automatically extend when pushed to the ground while using. Have been extending the line manually. I’ve found that I haven’t used very much line so far, and that’s a good thing.

Rated 4 out of 5 by from MYSTERY MANUAL Just purchased it. Thank heavens for You-Tube video posts because the manuals were hands down the worst I have encountered. Assembly instructions and cord loading instructions useless. However there are lots and lots and lots of safety warnings.
