I couldn't find any so I assembled some from bits.
Those are Warbases carts loaded with Busch pumpkins, hay and cabbages made from Hobbycraft stuff with Rapier miniatures drivers. I can't remember who the donkeys are from. Possibly Alternative?
They fit with the theme of the army -- which is that the farmland witches create it from the stuff around them when they need it.
Cavalry I was really stuck for and didn't want to do that many conversions so I went with the chariots instead. There's a lot of "Headless Horsemen" but they're all character poses and there's usually only one in a range.
