The machine size is pretty limiting, so I don't know if I would get to crazy into bucket sizing. I would defintely get the dirt bucket and the tooth bar would be a nice thing to have laying around when you have to dig out a patio.

As for the light material bucket, I would have to suggest a bigger bucket for the sole reason that a 54" bucket isn't going to increase capacity enough to make it worth while. Remember, if you have two buckets, you have to bring two buckets with you. It becomes a big pain to have to haul around two different buckets from job to job.

The main use of the light material bucket would be for mulch in the summer and snow in the winter. If you do big mulch jobs, it may work out well to have that bigger capacity in the spring when you typically install a lot of mulch. I have a standard 72" bucket on my 864 and find it too small when moving a lot of mulch. If anything, I would be looking at finding a light material bucket in the 70" range, which would perform well for mulch and for snow operations. Just not sure what a 553 can handle.

Also, I would strongly urge not buying a bucket with permanent teeth as your main line bucket. It may be a pain to take on and take off the tooth bar, but if you get a dirt bucket with permanent teeth, you'll hate yourself for it when you need to scrape materials off a drive.
