There are 7 Carts to find in total.

You will need to be F.A.R.T Level 10 (max level with 200/226 stars) to reach the final Cart.

Packmore

World Map - Once you are able to cross the bridge to the right of all the gnomes you’ll see this Cart in plain sight.
Catch Shack - hidden on the boat SW of the map

Snackmore

World Map - this is locked behind FART level 10. You’ll find it on the large candy tongue SE of where you start. (Breezy Boulevard)

Middle Folkmore

World Map - you will need to be F.A.R.T level 8 to be able to drive through the portal that leads to the cart.

The Void

The Floor is Void - Top right of the level you can move the arcade machine and walk through the tree to the outer room of the map. The Cart is in the top left corner.
Trained for This - in each corner of the map you’ll see a small wooden platform and a breaker, apart from the one where you see the cart. Hit the breakers in order to remove the electrics barriers.
World Map - top right behind the final level

I didn’t think to make a note of the cart levels until it was too late - if anyone mentions them in the comments I can add them to the guide
