I purchased a ck2610. After a year of use, my front axle started locking up. I was mowing (in 2wd) one day, pulling off the lawn on to the driveway and all of the sudden, bang, I almost went through the windshield. I tried backing up and then going forward and it broke loose. It has happened to me 5 times over the coarse of the summer. The dealership finally came and took the tractor October 10th, and they have had it ever since. Has anyone else had this happen?
