I have a 2015 Kubota ZD326 and I feel safe running laterally along steep banks that I used to hand mow because compact tractors (790 with a mid-mount mower) never felt safe. The center of gravity must be lower with the Kubota than with the compact tractor. Running downhill requires some caution as the rear wheels steer and brake but if operated too fast downhill the rear wheels become less effective as the weight shifts forward - especially when trying to brake. Mow slower if running downhill and it's fine.
