There is a better pdf version that list lease holders responsibilities and yours. Make sure you follow your guidelines and try to come to an agreement with the lease holder. If they refuse you can contact the land office for the area and they will calm and explain why you get access if that still doesn't work then you do a little paperwork and you should be good to go. Just had a problem with a lease holder myself. Make sure to be respectful they can ask you what you drive how many in your party things like that but access can't really be refused. This time of year cattle should be off the lease.
