I cut my horses mane. I hate pulling - and I learnt this great trait by my previous coach, who - trained under George Morris. If it wasn't for her who showed me this trick, I would never of been hired to take care of all the Fox Hunters horses manes, and been hired to braid horses manes for shows and comps.
It takes allot of time, and patience - but when you are done - it looks just as nice, if not better, than a pulled mane. Your horse will be the happier too.
I will cut it horizontally from poll to withers. Make it about a hands width *pinky finger to thumb* Takes a few times to get it all even, while I comb it out before I cut and directly after I cut. Allot of combing.
Then I take little bunches, starting from his Poll, in my fingers - and cut the bottom of his mane vertically. This makes the ends look natural, not all cut bluntly.
Then I take my thinning sheers, part his mane and thin out the under layer of his mane.
Remember, allot of combing - and do not do this with a wet mane. It must lay naturally.
The after shot isn't that great, his mane grew out some after I cut it - but you get an idea.
