I just bought a new L4600 HST and I only have 0.4 hours , since it arrived a couple of days ago, my only disappointment is that the range selector lever seems difficult to move from one range to the next, What it the trick ?? Is there a strategy, mine just won't go in low at times, I have to select another range and bump it and then try again. What is going on.... I tried this on a couple of other brand tractors and they are all like butter to move the lever not even running ??
