As someone else pointed out, this is not Expand-it type attachments & nowhere in the Amazon link you provided does it say it's Expand-it or attachment capable. I have a 40V Ryobi brushless weed trimmer Model #RY40230 & approx. 6 Expand-it attachments. They are all driven with a 1/4" square drive shaft from the motor down at the battery attachment area, thru the extension tubes that have 1/4" square drive shafts that spin inside said tubes & they spin the Expand-it attachments connected to them on the end. You have a weed trimmer head that only holds the battery. The tubes on your weed trimmer are used to carry the electrical wires & electrical connectors. At the end of the tubes on your weed trimmer you can connect your weed trimmer or your hedge trimmer but they are NOT Expand-it type attachments. Also the motors on your set-up/weed trimmer are at the very end of the attachments on your set-up making them much heavier than the Expand-it attachments because on the Ryobi brushless weed trimmer Model #RY40230 the brushless motor is next to the battery on the handle end & your set-up/weed trimmer has brushed motors on the far end of the attachments that are way more Inefficient depleting the battery much faster also. When you're cutting branches on a ladder or roof using 2 to 3 extensions for longer reach those extra pounds make a huge difference with all that leverage on the end & you don't want to have to get down to get another charged battery either using inefficient brushed motors & also because I have a very bad back. I had a few Expand-it attachments I bought at HD 20yrs ago to use with my then 2-cycle gas Homelite weed trimmer I was using so buying the 40V Ryobi brushless weed trimmer Model #RY40230 was a very good way to save money. I also love not having to go get fresh fuel & messing with 2-stroke oil mixing, cleaning gummed up carbs, cleaning fuel tanks, buying fuel filters & air filters, buying & cleaning spark plugs, buying new fuel lines, pull starting the engine a million times & getting blisters & the damn thing still doesn't start, etc., etc., etc.. Plus I'm helping the environment by switching over to electric lawn & garden equipment. BTW those same Expand-it attachments I bought at Home Depot 20yrs ago were only $49.99 each for every single one of them, now they are at least twice as much or more in most cases...
You need to put some lithium grease or penetrating oil on those blades. I can hear them binding from the friction. Spray them with lithium grease or penetrating oil and run them. I guarantee the blades will be quieter. You will get better and cleaner cuts and the blades wont dull out so fast. Spray them 2 -3 times during use. Dont use WD40 either as it cannot withstand heat and friction.
I don't believe so the 18v are a weaker system. The "Expand-it" line is 40v. Basically anything operating on a stick from pole saw to hedgetrimmer to weedwhacker to snowpusher to rototiller can snap onto the pole with the battery here. He also just informed me there's a 3ft extension for the system.
cool review, but not the expand-it line. expand it has engine/motor on other end - this is a trimmer on a pole type setup - weight distro totally different
