A few rules of thumb for normal clutch operation. Getting unstuck is not normal for these points.
-never ride the clutch (or any vehicles brakes) because you will prematurely wear it out
-when pushing in the clutch pedal do it rather quickly not slowly
-when releasing the clutch pedal you should do it slowly enough so it is not abrupt but fast enough as to not cause extra wear. A clutch job is not cheap.
Here's a few videos to check out on how a clutch works, hopefully these will help you understand the points above. Cars are very similar to tractors.

Someone mentioned not seeing why someone would keep the brakes locked together. I mainly use my tractor for loader work and my yard is very hilly. My brakes are always locked together and the tractor is always in 4 wheel drive. Otherwise I may end up going down a hill sideways. I really have no use for brake steering at this point.
