I spend a lot of time in the brush. Never had an issue getting it tangled (stupid blinkers, on the other hand.... ).
I like it. Not sure I'd move mountains to put one on, but glad its there, and I use it a lot. Doesn't matter that it only works at certain settings, because those are the only settings I use it at...
I have the "flat bars" on a bucket too. Nice, but I like the level better.
As an aside, I don't necessarily want level from it, but rather a certain angle relative to the tractor, which is exactly what it provides.
