I'm helping my dad do some yards, he's 70 but healthy as anything can be at that age. We usually do small yards/ business with push mowers, rarely a riding. This older lady wants us to do her Pasture, we are in Tx btw, She's around Eagle's Landing Avinger, I don't know if anyone here knows of it. Anyway's it's her mower a John Deere 54 inch zero turn, but her pasture is 12 acres, my dad said it's basically in the woods, but there is alot of openess. She also wants her fenceline trimmed. My dad has never had a circumstance like this and doesn't know what to charge. He has never used anyone else's equipment, nor did this much land. He told her maybe 12/hr. In my opinion the trimming alone is worth 20 minimum, what do you guys think? That's a BIG fenceline.
