Firstly, if your farm is rented, then you must have a tenant and a written lease with a "strong" Idemnification Clause.
No? Then hire a darn good attorney to implement one that idemnifies you (and all concerned) from everything imaginable and have your tenant sign and incorporate it into the lease. The tenant's cow could fatally step into a hole or his crop could fail or something the Operator did that took on an adverse effect for the tenant ... whatever! It could turn into a liability issue.
P.S. Besides having a "strong" Idemnification Clause in a farm lease, farm liability insurance can be added to the Homeowner's policy. And/or you may want to require the tenant to purchase liability insurance and make you an additional insured under the policy. (I live in Texas.)
Thank you.
