Our neighbours are a horse farm on one side and an arable farm on the other, with the road at one end the canal at the other. The horse farm neighbours are friendly, and we have visited them, and they seem pretty positive about what we are doing. They have a small number of industrial units and it was one of their tenants who advised us that we had been fly-tipped.
The farmer on the other side we see rarely, as it is usually an employee who does the ploughing/harrowing/harvesting. He doesn't contact us or help at all, which means we have to cut our own roadside hedge instead of chipping in to have his bloke do ours with his flail. He also cut down a large branch off a TPO protected oak in our wood in order to do some drainage work on his land - he could have phoned us and we could have got permission, now we are liable for the damage he has done, should anybody complain about it. It hasn't damaged the tree, but he still shouldn't have done it. We mainly have contact via his vermin control man who shoots the pigeons and rabbits. We will need to contact him about possibly ring-barking two sycamores on his side of the boundary - goodness knows what he'll be like about it.
