In my 16 months experience pulling a 630 pound Rollover Box Blade behind my Kubota B3300SU/33-hp/1,900 pounds I agree with Travis at ETA.
I have about ten implements which mount on the 3-Pt hitch. It has taken me longer to master the ROBB than any of my other implements. Implement weight is CERTAINLY important but so is adjusting the top link to the optimum length for the blade to perform best for the descreet task you want the box blade to perform; with cutting and smoothing requiring different top link lengths.
Yup, I'm all to aware of the difference shortening the top link can make. I welded up a frame on top of my BB, added two stainless steel 55 gallon drums on their sides and plumbed it all together to make a zamboni for the rink. I forgot to check my angle at the beginning of the year. I wondered why I could feel the zamboni when pulling. Didn't take me long to see the 20' long, 6" deep ruts I was carving into the ice because I was tilted way to far forward and the sides were digging in. A 400 # BB + 1500 # of water will go though anything!
I'm mostly in clay, and while changing the angle of the box blade with the top link helps, it's not always enough. The DK45 weighs about 6500# with loaded tires. That's a lot of weight to be holding back with a 500lbs box blade. EA's is probably the nicest that size I've seen, and I'm sure it will do a great job.
