I have a new 354LE that appears to be stuck between 4WD and 2WD. I put it up on block stands to see if taking the pressure off all four wheels would help. But it only grinds when I put it in gear. The handle will move about 1 or 2 inches but will never catch and it appear to go in and out of 4WD and 2WD when I put pressure on the handle but if I release it only turns the back wheels and make a grinding sound. I have 14 hours and the tractor and the dealer said he only warrantees the engine for 6 months and anything else is my problem. Any suggestions would be appreciated
