I know pigs are good tillers, but thinking packed gravel might be a bit rough on them. All advice welcome.
They don't work for free - They probably can till up gravel like that, but they won't do it just to do it. If you were to seed it with corn and put some large pigs on there you might have some success.
That depends to some extent on what you mean by 'packed gravel'.
A pig's natural instinct is not to destroy - it's to graze and decompact in spots distributed throughout an area then move on.
I've certainly had them till up paddocks, but they'd rather be doing this...https://www.youtube.com/watch?v=8vbPhMeRXuk&feature=youtu.be
Clearly I don't know the spot, but I'm thinking you might have better success by feeding cows on a round bale in there for a bit, then planting some deep taproot stuff in that, then cycling pigs and
cattle through it alternating. The pigs are going to be a lot more likely to dig up some daikon radish than they are just randomly to dig up the gravel.
