Thanks so much, Deb!
Nope, no tractor here. There's no place to keep one unless I fence off part of the pasture, and then I'd need to build it a shed.
The idea of a pull-behind brush hog would probably work very well!
I could probably even rent one twice a year (maybe?) instead of buying it and then having storage issues.
I don't know if she'd eat toxic weeds, but the worry is still there. She's been here 15 years so far, with no issues, but the weeds are more plentiful than the grass this year.
She's fat and sassy, so I wouldn't think she'd be tempted, but the weeds still need to go.
