If this machine lives through all this whacking I will write a testimonial for the company!
Problems with the design of the machine have emerged. The half-sphere below the strings that comes in contact with the ground (sorry can't locate manual to use the proper name for it) keeps coming unscrewed. I wonder if it is threaded in the opposite direction that the trimmer head turns so it unscrews every time it contacts the ground, which is very often. If so, BAD design. Don't know why it would unscrew otherwise except maybe just from vibration.
Fortunately it is a large piece of metal and not too hard to find after it comes off. I used nailpolish to glue it back on last night, as recommended by a mechanic firend. We'll see how long it stays on today.
Ohter problem is that it uses a tiny little set screw to hold the trimmer head at the height you want. It has not held the adjustment and I can just see that in the future I will strip the hex head of the screw or break the hexT trying to get it cranked down to hold the head where I want it. So today I am just going to see if I can live with whacking at the lowest setting, where the trimmer head ends up with no set screw (guess I better take that out and put it somewhere safe). It seems to throw a LOT more debris at that lowest setting, which makes sense, and is unpleasant.
Can't use a mower. Ground is too lumpy, too many rocks and gravel.
