Sounds like something is binding. or belt is slipping. Does it smoke when not in gear. Check and see if everything turns by hand when out of gear and no motor running. Make sure its not binding anyplace. If that is ok Start it up and just idle the engine and try to run the deck and put it in gear. If that stalls it out then you do have a problem.

SOURCE: loud screech noise from deck area

This can be due to a belt slipping or a bad spindle bearing.
And on the difficulty scale,10 being extremely difficult, The belt would be a 1 or 2 and the spindle about 6 or 7 (because the deck usually needs removed for this job)

SOURCE: White smoke from my Craftmans tractor,

Use the lawnmower's oil dipstick to determine whether the oil level is correct. Maintain the correct level of oil. If you've overfilled the oil, open the drain plug, and drain some of the oil into a waste container.

Dispose of any excess oil properly. Burning off excess oil is undesirable. It can foul the mower's spark plug, piston rings, and other engine components and contributes to air pollution.

If your mower's engine has not been overfilled with oil, but still is smoking, it may have stuck or worn piston rings or another maintenance problem.
If it has sat over the winter, and didnt have stabilizer in it - it may be bad gas too. Drain it out, and put in fresh.

SOURCE: what would cause white smoke from the front of my

It could be your valves. My friends mower was blowing a lot of smoke and I think some oil. I replaced the valves and it runs like a dream.
I can't remember the steps to remove and replace, sorry.
If you are mechanically inclined it shouldn't be that hard. The only problem I has was the new valves (keeper or whatever holds them in place) was different than the old one.
You could call a repair shop and get an estimate.
Good luck. Let me know if this any help.

The oil on your pulley could definitely be the culprit. You need friction in order for your belts to work properly.

I have CraftsmanLT1000 lawn tractor, Smokes heavily.

First check the oil, not only the level but the smell
if its overfull and it smells like gasoline then the problem is that your carb is dirty or the float is sticking and flooding the engine with gas. If the oil is at the correct level then the problem is more likely the valve stem seals, as the engine warms they leak. I presume you have checked the airfilter is clean? The choke is comming off completely when you move the throttle cable? The LT 1000 is the entry level rider in the sears line. The engine usually starts wearing out in about 50 hours use. Remember the sweetness of low price is long forgotten with the bitterness of low quality!

Wont go and screeches when letting off clutch/brake

Take off the shift plate between you legs, put it in nuetral, crank up the engine, put speed lever in high gear and slowly let off on the clutch. Everything will work as if in gear, it just won't move. you should be able to see what the problem is. Which belt did you replace and why? Watch the varible speed pulley (the one both belts go around). The bearings may be bad in it and not letting it turn, thus, smoking the front belt.

Hard starting smokes white like gas is getting into cylinders

White smoke in a small engine is oil. Oil in the cylinder will create too much pressure for the engine to achieve compression. Make sure the engine is not getting fuel into the oil and thinning the mixture (literally smell the oil... gasoline and oil smell nothing alike, if it smells like gas, it is). If this is the case, the carb is leaking fuel into the engine, thinning the oil and causing the oil to leak past the rings into the cylinder head, through the valves and, from there, into the exhaust to burn off. Black smoke indicates a direct fuel issue in a small engine, white is oil based.
