so today i replaced both belts and it ran flawlessly until it this the heavy wet snow check the pins and there fine and the belts again it looks like the gear wheel is locking out that the belt is on but when not on load of snow works fine

Welcome to the forum!

What machine is this? And what is stopping, exactly? The impeller that actually throws the snow out the chute? Or the augers at the front that chew up the snow?

Maybe a photo ?

it is a husquvana st324p the impeller stops and well as the auger blades. and start to burn the belt if i put more presser on the small wheel the engages the impeller

Is the Auger belt idler pulley(clutch) adjustable???

yes it is and put on full tench-en on the belt it wont move at all if there is a load in the front of it the engine wheel still spins in place and eats the belt

Impeller is Jammed or Gearbox is Toast. Can You move the impeller by hand? If Not, Something is jammed in there or gearbox is toast. Put a piece of 2x4 in the chute resting on an impeller blade. Hit 2x4 with Large Hammer until it frees up.

every thing works fine when there is no snow in it tho. i cant move the impeller by hand when its off that what i dont get

Hold down the Auger Engagement Control, and Hold it down with Vicegrips or a clamp. This will release the brake. Then try to move the impeller by hand.... Is it Possible the auger belt is routed incorrectly?

any i able to send a video here. the belt is right route seem like the belt dosent have enough grip or the snow is to heavy for the impeller because the impeller back wheel doesn't move at all when there is snow
