Drive belt for belts jumps off and gear shift mec. sloppy

I do love my Yamaha ys624, but this winter some problems started. The gear shift mecanism started to be difficult. Not able to shift from 4 to 3 but beeing wiolent it worked. Getting it into 1 almost impossible. Then, no movment on drive belts at all, no matter first or any gear. Removing the cover in front of engine - the belt pulling the drive belt was off with no damage to belt.
Do I have to dissasembly the hole thing to get the belt back on?
Any tips on why the shift mecanism is so sloppy?
Regards Norway - had tree feet of snow and the snowblower is broken hundred some meters from my garage - upphill-----!

Check the condition of the belts; kevlar belts are avail. thru a good auto machine shop.
You can trial & error (& common sense) play around with the shifting linkages/adjustments (best to be using a manual for reference).  Also check the 'underworkings' of the machine (remove bottom pan)-(easy).  If it sticks in 2nd reverse on my YS-624T it means the cotter pin has gone (at the end of the hex shaped shaft).  This has happened more than once (the 'drive wheel' has travelled too far).  Easy to replace w/standard cotter pin...

Found the entire manual thru this forum. I em wery grateful. Turning the Yamaha over and opening the bottom cower solved the problems quikly. Some adjustments, a little bit of lube (grase) to linkage, v belt back on and it runs like a dream. The snow that used to be in my garden is naw at the other side of the fence:)
