Trying to find drive belt for Kubota Z421 part # K3071-13560

[rick sheltra]

Would anyone know where i could get a drive belt for my Z421 Kubota? They seem to be sold out everywhere. Are the OEM replacement belts ok to use. The prices for genuine items seem to be way off, $125 for a belt. Any advice would be most appreciated.
Thanks Rick

UPDATE 07/21/25

So because of work I still haven't got time to take the deck off and inspect the damage...with any luck it will just be the belt. I added up all the possible parts that could possibly need replacing (the nuts for the spring and tension bar etc) just those few parts were like 40$ So I will just order a belt from Messicks as i know it is broken. So glad I had somewhere to go for advice....
Has anyone ever tried to access that belt by removing the gas tank? probably not a good idea....
So now i just need to locate a diagram for the mower deck as i want to see the belt diagram. I cant find it on that kubota site... sorry to ask so many questions I appreciate the help

It seems to be a 1/2" x 77" vbeltakak A75A or A75K, so any made with Aramid or Kevlar should be fine. One place has them for $10 US$ !!

$125 for a mower belt?

That's insane.

Rick, out of curiosity how long has your oem belt lasted?

My MMM belt is 2 years old and I'm hoping for several more years of use. . .

I think I bought the mower about 6 years ago. Could be wrong Im getting old like the mower. Only issue so far besides hour meter never working.. Also both kill switches for the seat and brake are intermittent since new. My drive belt is original equipment same with the deck belt. The only thing that really failed was the bearings in the blade mandrels. The ones that came with it and failed in less then a year were chinese in this japanese tractor. Had to get new bearings forgot where they were made but it wasnt china. Other then that it has been great.
I think I am going to remove the deck and check the fan blades as well.
