Have a 1640a fel on my b1550. The bucket needs a new cutting edge badly. the bucket if 4ft wide. I would like to know if there are other Kubota buckets that I can interchange with that would be larger, for snow. The one I have is very small and rather than put money into another cutting edge would like to get a bigger bucket for snow clearing. I would also like to hear if there is anyone who made extended top and sides for their buckets for snow then remove come summer again.
