Like someone else mentioned, pull manes after a workout, when she is hot and her pores are open. Also, make sure you really are only pulling a few hairs at once, and that its a quick, sharp motion, instead of a slowww drawn out one, I can imagine that hurting a lot more.
If she only acts this way when you pull her mane, its obviously out of pain, nervousness, etc., which is understandable, although is definitely not a reason for her to be acting that way in my opinion. You could always try a hay net or something, maybe she is just focusing on what your doing too much to relax? I'm not saying to keep her from acting poorly, but rather as a reward for good behavior, if that makes any sense?
BTW my mare HATES clippers at this point, too, but all I can say on that is just taking the time and the patience to desensitize her to them a little every day.
