If the second belt looks cracked or frayed, it will keep you from the aggrivation of doing the job twice if you change both. If it looks good, I wouldn't change it though.

Multiple belt drives run "matched sets" so you must replace both to insure equal loading.

And it needs to be a "matched set", not just two belts with the same number. They are packaged as sets to make sure they are exactly alike, otherwise you risk premature bearing failure and other unpleasantly expensive results.

I ran into this dilemma once with a table saw.
Place I used to work had a big Powermatic table saw.
It had 3 belts on it as a matched set.
If one of the belts broke it was ok, we could still use the saw.
But when the second belt broke we had to replace all 3.
But we saved the 3 belt for later use.
I was told that the belts become stretched over time.
And they all 3 stretch approximately equally so they stay matched.
But for putting new belts on, we had to put 3 new belts on at the same time.
Except:
we saved the old unbroken belts, and when we got 3 of them,
we could put those 3 on the saw and get a little more life out of them.
It just took a few minutes to change belts on the saw.
And this was more cost effective than just trashing them.
You mite want to do the same for your finish mower.

You guys must have gone through a lot belts on that saw for someone to think about that one. Good idea, though.

....Maybe this was true many many years ago, but today if you pull two belts off the shelf with the same number, they will be pretty much the same. Compared to the forces exerted on the blade, the load on the spindle bearings from a properly tensioned belt is slight. I see no need to pay a premium for a "matched set....just buy two belts of the same number from the same manufacturer.

We sawed hard rock maple 8 hours per day.
The pieces were all 22 inchs long and 7/8 inch thick.
Had a power feed on the saw. Fed about 5 inches per second
Just shoved the stock into the feeder and it went thru the saw
and a guy on the other side took it out and stacked it.
Scrap went into the scrap barrel.
Each new piece butted up to the one before it.
It was like sawing one long piece of wood for 8 hours.
Belts were about 14 inchs long.
We went thru about a set per year every year I was there.
What suprised me the most is we didn't go thru more sawblades.
Only went thru about 3 blades per year.

Matched sets only apply if the belts are all running in the same pully's. If the belts go around one common pully and then to different blades, they do not need to be matched. It will not matter if one is stretched longer than the other.
A matched set also has to be purchased as a matched set. Just buying tow belts the same number off the rack will not work. A matched set is matched from the factory.
