Don't believe these posts- you've got a drive system defect, or Bobcat has a false advertising problem.
What series do you have? Do happen to know the date of manufature or have your serial number handy? Are you very experieced with how a 4 wheel drive vehicle handles.
o7 serial number a0w11660 , i have noticed all 4 wheels are spinning, i'm thinking the tire tread pattern and damp sandy soil combo give the toolcat trouble , it climbs great pushing the 90 inch mowing deck up hill if the soil is dry and not so sandy thank you
