I've joined this forum as I've moved on to a lifestyle property which has some quite steep areas. The property is 40% in lawn so i'm hoping to get some recommendations on managing them without pushing some lame domestic lawn mower.
Members have stated that zero turn mowers don't do well on slopes. I would look for a wide-stance, low profile tractor with 4WD. Assuming "lifestyle property" > 1 acre!
If you want more recommendations, you may want to move this post or start another one in buying/pricing.
