TB 110 Hard to shift !!!

[pharmvet]

Shifting gears in my TB110 is very difficult. They are very tight (sometimes very hard to move from High to Low or from foreward to reverse) and its difficult to keep them from grinding during shifting. I have learned some tricks to minimize the difficulty but it seems extreme. My 7710 shifts much easier, as did a 3930 I owned previouisly, and my John Deere 5303. Is this just the NORM for these TB series tractors, or is there something I can do to help matters ??
