I have State Farm. The home policy covers a certain amount of equipment used to maintain the property. When my 5105 burned, it was part of that policy. Just talk to your agent with a rough value of what all of your equipment is worth. It doesn't cover anything off of my property though.
For my 5055E, I have a personal articles policy that is pretty reasonable. It also covers it off of the property, which I requested. It won't cover for commercial work, but if I'm brush hogging for my neighbor or helping them move something, it's covered.
