Posed this question on lawnsite and awaiting a response.
With years of industrial experience I am very familiar with the difference between 5v and B section belts. And they are pretty much considered NOT interchangeable and even use different pulleys/sheaves
Well, in my semi-retirement I took a part time job working for a friend that owns a local landscape company keeping their equipment serviced. They have a dozen or so mowers.
One thing I am trying to accomplish is inventory and application of the various v-belts for the mowers and such. And I have hit kinda a snag....
They have two toro grandstand mowers with 61" decks. Model # are different, 74583 and 74513. BOTH use the SAME spindle pulleys....toro # 120-6434.....so one would think they use the same belt right.....WRONG.
One uses a toro belt 106-7369, which is a B-section 175.625" belt and crosses to a gates/napa bladerunner 6661br.
The other us toro # 131-1123, which is a 5v section, 175.00" and crosses to 6885br
There are two other mowers. Both toro 6000series 72" decks. One model # 74961 the other 74928. And like the grandstands, they BOTH use the SAME spindle pulleys.....toro 105-7733
Yet....one uses a toro 109-9023 belt which is 5v, 219.25" long, and crosses to a 6851br
The other uses a toro 114-5859 belt which is a B-section, 219.625 and crosses to a 6884br
Can anyone explain a reason behind this?
Or more importantly.....what would be a reason to stock 4 different belts for these 4 mowers instead of narrowing it down to 2.....since for all intents and purposes the belts are the same length?
It would be a lot easier pill to swallow to stock all 4 different belts if the sheaves were different and specific to a 5v or B application. But they are not.
Anyone ran across this before?
Also, just FYI incase anyone else uses bladerunner belts from napa or where ever.....there is ALOT of overlap on sizing and BIG difference on pricing. I actually took the time to spreadsheet out all of the bladerunner belt #'s and sort them by size for this specific reason.
Just as an example....One of the belts on the toro 72" mower crosses to a napa 6884br. b-section 219.625" and price through napa is $113.15
Well a 6947br belt is 219". (5/8" shorter isnt gonna make a hill of beans difference on a 219" belt). Cost is about half at $66 and change. BOTH are aramid/kevlar belts too
Another example is the cross reference for toro 110-5043 belt. B-section, 121.25". Napa crosses to a 7048br which is $91.07 a 6574br is also 121.25" b-section aramid belt and is $68
These are just a couple examples but the same can be found all across the spectrum. That was a little off topic but I am really curious as to why some toro belts are 5v and some are B section with the same pulleys?

the belt that sits perfectly in the pulleys is the correct one!..
