Insert your spade along the root line and that will speed the ripening up.
Learned that tip from Joy Of Gardening by Dick Raymond

We have about a dozen tomato plants (Cherokee Purple, Better Boy, Super
Marmandes, Brandy Boy). Lots of good-sized tomatoes ... all GREEN.
It's been a wet summer, which I suspect it will continue to be. And,
we're losing sun anyway.

Is there a way to push to ripen faster? In particular, would pruning
help? I heard once that you should cut back new growth that won't have
time to mature. OTOH, my past experiments with pruning have just
produced very low yields. Maybe cut the small fruits and new flowers?

Any thoughts would be appreciated.

Thanks,
