With the stock line, it sounds a little rough. The Milwaukee 3006 sounds like it should have more vibration than it does. It does an excellent job in low yet has the runtime to get some serious work done when you need the full extent of its muscle. The big takeaway is that you don’t have to manage your battery usage as carefully as we’ve seen with other battery-powered string trimmers. With the power Milwaukee is putting out, I wouldn’t have bet on a 30+ minute runtime in high, even with two batteries, but you’ve got it. High speed netted an impressive total of 30 minutes and 59 seconds. For both tests, I used Milwaukee’s stock trimmer line at the full 17-inch cutting diameter with two fresh, fully charged 8.0Ah High Output batteries.Īt low speed, the trimmer ran for 54 minutes and 4 seconds. I tested runtime at both high and low speeds. Just like previous models I’ve tested from Milwaukee, this string trimmer is dialed in to accelerate the line up to full speed in less than one second. For the way I trim, that’s 0.095, but I wouldn’t hesitate to switch over to the 0.105 if I know I have overgrowth on the menu. With the performance I experienced, I recommend going with the line size you’re already comfortable using. The trimmer can also step down to 0.080-inch or up to 0.105-inch line. That was using the stock 0.095-inch line. It was only when I got into heavy overgrowth that I really needed the additional power to keep the line speed up to its max 6200 RPM. For regular maintenance trimming, I was able to work in low speed (4900 RPM) while keeping up my normal pace.
