Right on HorsePlay! I've been riding with my horses for years now, won the Onewheel Summer Camp contest back in 2017 with a short vid of me leading my horse around the property. I too learned to ride on my grass and dirt property and was thankful during my many spills and falls. I started by riding around my horses for a while so they got use to the noise and now it doesn't bother them at all. Trick is to not have them pass you on the lead and to be in a place where you can let go of them if need be!
Good luck, be safe and take it slow!
