4low to pull a bush out of the ground?

Might help to cut it all the way down now, leaving enough to strap to but no greenery. By the time you pull them in a month or two, maybe the roots will be a little weakened. Just totally made that up, so don't quote me. May not help a damn bit, but won't hurt.

 

Leaving a length of trunk gives you a lever

 

True dat

We leave the trunks about 4-6 feet in order to pull them out with any sort of machinery, from trucks to D-9 cats, if you cut them flush they are 100x more difficult to pull out, at that point it's easier if you grind them with a stump grinder if they have any size on them at all.
