Every mowing I get better at coping with the problem areas, but that doesn't make it enjoyable. I've tried every approach angle and steering combination and it simply won't operate in those areas. There are a couple of slope where the Toro simply won't turn; it runs downhill and jumps into the fence like it is magnetized.
On your recommendations, I'll consider traction tires and/or filling with calcium chloride, but it's a bummer to learn the newer-supposedly-latest-greatest ZT requires major and expensive tire modifications just to operate as well as the olde stone age tractor mower.
On the plus side, the quality of cut is maybe better than the old Cub Cadet and of course, it's much faster. With the engine behind, it's subjectively quieter.
The Toro also starts instantly with no choke required in warm weather. On the CC, no matter the weather and even with a fresh tuneup, the old 13hp Kohler banger was a cold-blooded beast and required at least 15-20 seconds of choking and cranking to git 'er going.
