Hello all, I recently purchased a Husqvarna MZ6128 to mow five acres with. I like the 3400 hydros and 61" deck as well as the 23" tires. At 9 hours the B&S engine went , it now has the B&S Cyclone engine out of Husqvarna's commercial mowers. With 17 hours on it the right front fork will not turn. It is under warranty but I am far from the dealer and don't feel like paying them to pick it up again and pay them to deliver it. I took off the bearing cap and there is plenty of grease in there. What would cause the fork to seize at 17 hours, and how might a fix it? Should I try loosening the castle nut? or call my dealer again.... thanks for your help!
