My CK20S has 1100 hrs and is going strong.  I had 2 incidents since buying new.  First was a pesky fuel solenoid that just needed re-seating and second was a bolt sheared off inside the bell housing (loosened off from factory) which required splitting the tractor.  Has been a great machine.  Good oil and regular maintenance are key! Would buy again.
