having trouble finding deck belt

[olddude 10]

My son has a 312-8 Wheel Horse he gave me a SN of 2112K805 and from what I think I have found it's a 1988 model year. The deck plate with that number on it is gone so I don't know what deck it has under it.  I measured the belt or what is left of it and it was 139". And it was some sort of a double V belt. Everything I seem to come up with is the decks with this length of belt had just one belt for the drive and the deck. This one has 2 belts one for the drive and one the deck. It has two blades and I'm pretty sure it a 37' cut. Did some of these things have two belts with the double V for the deck and a regular belt for the drive/mule?

There is only one deck with 2 blades which is the 37" for this model of tractor. The 6-sided belt is all it needs. Click on the pictures to read more or download manuals

Thanks....I have already looked at these downloads and a bunch of the others but I'm still in the dark. I don't have the mower here so that I can look see and am just going by what he's telling me. The pic above looks like there is just one belt for both the deck and mule. He's saying that there are two belts on this deck. I'm hoping he will bring it by so I can look see what he really has.

It sounds like someone unfamiliar with these tractors put the two belts on there.

The mule or idler assembly for this deck has two V-idler pulleys and uses one 6-sided belt. All the deck pulleys are the V-style.

All other decks have one V-idler pulley and one flat-idler pulley and require two 4-sided belts.

 

The next version of this deck 05-37SC02 uses flat idlers and a mule with one of each idler to run a single 4-sided belt the same length as the 6-sided belt.

 

Some owners have changed idlers and belt style.

 

It is possible the owner has both styles and has them mixed up if they have other sizes of decks.

 

To require 2 belts the center deck spindle pulley is a double V-pulley.

Nawh he only has one tractor. I've looked at it before but didn't pay much attention to the belt drives. He may have the one you noted in the second line of your last post. I've looked at all three types and from what I see is that those have a shorter belt for the deck. The belt he brought me was at least 139 1/2" long. that's where my hangup is.

 I got to the bottom of this. I drove over to his house.....only 45 miles away, and the second belt he was talking about was the main drive belt for the tractor. The deck only has one belt that drives both the deck and the PTO. Sorry for the trouble.
