Sounds reasonable to me, if they get mad apparently they are just jealous of your tractor.

Now that we have all of our pastures fenced that have county roads cutting through the middle of them there isn't much of an issue.  Just astonishes me how many on here figure because they can't see any damage done then trespassing is A OK.  I wouldn't do any damage barging into your house watching your TV, using your shower and taking a nap in your bed whenever I like but something says most would have an issue with it.

I feel for you with Horse owner problems, they are the absolute worst.  Won't feed them in the winter, won't pay for their hay when they do feed them, won't fix the fence the horse walks down and think they can ride anywhere whenever they want.
