Okay my lawn is mainly vigorous weeds but, has some grass too. First time I was able to find someone to mow it - grass was to the top of the fence. Guy said he'd have to cut it twice, his mower couldn't take so much off at once. Ended up being $ 100.
After that when it was growing back I sprayed it with Round up- it came back anyway but not nearly as tall.
