The R&D department decided that the buckets should be 60". In the past, the CK20, and others, had a range of buckets offered, but they decided on a size in the middle of the range because they felt the larger buckets were oversized for the tractors.
I suppose this came from damages that were repaired under warranty, or just that the engineers revisited the issue and realized they were overstressing the loader arms. Either way, what they sell is what the engineers recommend one use.
