Well my dad always rented a bull to the neighbor and it used to be $800 a summer over 10 years ago.

Not sure if he still does it or not.  Who pays for a bad leg or a broken pecker?

Is it the "right" kind of bull?  I am sure it ain't no $4000 plus bull for 3 cows.  So do you really want to use it for the cheap?  not being a prick, but I know guys with 3 cows and I would not use those things they have running with there cows.
