I have a 6.5 hp commercial grade DR wheeled string trimmer. It is well built. The thing I don't like is that when I trim along edges (planter in middle of lawn, interface of lawn and rock cobble lined streambed), the strings don't reach past the wheel. I have to approach the object perpendicularly, swivel and cut about one foot, back away, move down, turn and approach perpendicularly again. It can tilt off center on the axle, but that still doesn't "cut it" very well. At least this thing is offset. It also fits my philosophy of maintaining as few internal combustion engines as possible.
I wonder if its offset design throws the center of gravity off so much that it's hard to get on/off the 3ph. Do you have any idea on the price? Do you know whether it will pivot to the opposite side?
