I purchased this tractor primarliy to use to haul yard debris.  I use it occasionally to mow with.  When I first used it, I hit a rock and broke the Mandrel Housing on the right side blade.  I called Sears up and they came out in a few days and repaired my mower for just a $20.00 house call.  WONDERFUL!  A few weeks later, I was mowing again and managed to destroy the left side Mandrel Housing this time.  I called Sears again and they came out but  would not repair this one for free (under warranty).  Ok, no problem.  It was my fault after all.  So I call Parts Direct to order the replacement...
