I’d wait till spring and grass is growing. Buy the X590 with HDAP tires. Without pictures of your slope hard to say, but if the craftsman did it the X590 will laugh at it. The 590 is much wider (more stable on hills) bigger tires and the locker. Personally I have a neighbor that had a hill he couldn’t do with his husky, refused to climb the hill, ran away going downhill, and slide like crazy trying to cut it sideways. So I said I’ll give it a try- with my X590 I could go up the hill, down the hill , across hill didn’t matter. Needless to say he now owns a john Deere. Anyhow I say wait till spring and grass is growing, buy the X590 – 95% chance it works fine, but if it doesn’t use John Deere promise and go with 4WD x7xx series tractor (a lot more money)
Sensible advice. Thank you
