I just purchased a John Deere 450E LT and have found many undisclosed problems with the machine but the one that I am most concerned with is that Low range does not engage until I have raised the engine RPM's to about half throttle. (No Tach) High range and reverse engage at an idle but not low range. Once it does engage it seems to stay in and operate fine as long as I keep the RPM's up. Any help would be appreciated.
I'm also looking for a repair manual if anyone knows where I can get one.
