Stufe35, it would be normal and common courtesy to inform your neighbour that you were going to make use of your access across their land.
He could then arrange his livestock accordingly.
My house has a half mile track across a neighbours land to get to it. Are you really saying I should give him a call every time I leave for work, go to the shops, or the postmans coming, or grannys visiting, or im popping home for lunch ?
I have to disagree with you . What is normal and common (and in fact a requirement of law) is that landowners should keep rights of way clear and available for safe use by the people that have the right to use them. No advance notice required.
This is not a discourteous expectation. Their advance notice that people will be using their land is written in their deeds.
