Hi all...I am looking to buy a new tractor to replace my John Deere Sabre 22 hp with 54 inch deck that lasted 20 years. I have three acres to mow with plenty or trees and a moderate hill to climb. I used my Sabre to pull a lawn roller (550 lbs), pull my roll in dock in and out of my lake (500 lbs.), and haul stuff under 400 lbs. with my utility trailer. I'm trying to decide between the John Deere X380 vs the x570. There's about a $2000 difference. Any thoughts/ advice is appreciated. There are no used models out there. Thx!
