Outdoor Power Equipment (Lawn Mowers, Snow Blowers, Chain Saws and more) Discussions

I have a 4 year old Toro 3650 and it has been very good.  However, of late it has started to squeal alot when it is under a strain from a bit of snow when before it used to go right through it.  I presume this to be the drive belt?  Does it need to be adjusted (if possible) or simply replaced?  Is the drive belt replacement pretty easy if that is what you think it might be?

Thanks in advance.
