economy power king tractor

It is a small tractor 2 wd with some parts common with a international cub it is powered by a kohler 14 hp gas .It is shaft driven with rear hydros.The neighbor has cultivators on it .For light work it works well.I am leaning on a frozen throw out bearing as the problem.But I have never fooled around with one sooo,I am looking to minimize mistakes by asking first.
