Are there any owners of SC2400/2450 or EA2400 (Australian owners) that have a 4 in 1 bucket? I'm asking as I am wondering if the weight of the bucket significantly affects the pay load weight that can be carried. Yanmar specs says that the lift capacity 500mm forward of the pivot points at full height is 550lbs. How much less should I expect given the extra weight of a typical 4 in 1 bucket. Mine is around 350lbs which seems a significant reduction. Should I be getting better performance than that?
