What you need, JF Ranch, is an old IHC Scout like ours.
We have a
calf carrier that (I think)
is made out of pipe and is hooked to the
back of the Scout. You attach it to the ball of the vehicle and it goes up
along the tailgate. The calf is in it with his feet hanging down.
You can secure them with a seat belt or whatever. The old cow
likes it that she can see the calf really well and she just comes right along.
Best thing we have ever found!
Our local 'inventor genius' made it for us and one for himself.
Oh, and we just happen to have one for sale.
