tires having a hard time spinning
 

Ive noticed that when im in deep snow pack or thick mud my tires arent turning unless i give it much throttle. It tows rv on pavement and shifts fine. Its just sluggish in snow pack when i get moving from a stop

When you give it throttle, do they turn ok? Is the engine speed high before they start turning?

Yes. It feels like tires are frozen and takes a good amount of rpm.

Once they break free its just fine. For example if on a logen road during hunting that has bout foot snow and im first tracks and want to turn around. My three point turn is when tires are "stuck". Goose the pedal and they get unstuck and throw mub n snow all over the place.
