I just got a new DR walk behind, and I love it. The power differential makes a huge difference. I have a couple different groves of cedars in our backyard and try to trim under them a couple times a season. It's a chore I've always dreaded, even with a high powered straight shaft trimmer with a good harness. What's always taken me two full days with a regular string trimmer got done in two evenings after dinner. I could get much closer to the tree trunks without scarring the trees than I ever could with a handheld trimmer. When I run a regular string trimmer, I'm covered head to foot in clippings. I barely got any one me at all with the new DR. Like Curban wrote, with the .175 line, it will take down anything that's not woody (and will take some that are). There's an optional Beaver blade that has chainsaw teeth if you want to tackle saplings. I haven't ordered that yet, but after the first few days using this, I think I might. One thing nice about the DR is that you can pivot the frame relative to the axle so that the head sticks out to the left of the left wheel. You can trim under your fence while walking straight down the fence line, with very little back and forth. DR is clearing out last year's models, at the same price that most places have the Husqvarna, which doesn't have the offset feature, has a more complicated cutterhead, has a smaller engine, and doesn't have the option to add the Beaver blade (or any other cutting option beyond line). I thought the big wheels would walk over ruts and rocks better than they do, but that's my only gripe. If the ground is relatively smooth pushing the thing is like pushing an empty two wheeled dolly. It is very well balanced.
