Allis Cahlmers 310 belt lengths

I have an AC 310 that was my father's. I just got it going, but the belt that runs off the crank to power the mower deck was stretched and now broke.

I'm trying to find the proper belt length to replace it.

The vari-drive belt and the deck belt are OK, but I can't find info on the web.

TIA,

John

I got an 81" belt but it's too loose- falls off when mower drive is disengaged. My brother found some documentation and I got a 79" belt. It may be a little tight, as the blades never completely stop, but it's much better than always falling off. An 80" might be ideal, but I've already spent $50 on belts, so I'll stick with the 79".

Oh yeah- it doesn't have an electric clutch. I didn't pick up on that until I got into more work it needed.
