I just purchased the smaller Walco dump box for my BX1850. The size is very proportional for width, however the 36" depth seems to stick out a little more than what I would like. I did fashion some CubCadet wheel weights, 4 25# weights and brackets totaling about 125# for the front. I have been hauling firewood and dumping directly into my coal chute that leads to basement and have to say I love this thing. I don't know that I would load the box completely out to the end but the sides are high enough that I can stack quite a bit towards the tractor and some more pieces in the second row to get the weight correct to dump. Keep in mind, the smaller box does not have a tail gate but rather is angled up much like a wheel barrow. I also have a carry all that I built a box on that is 48" wide by 30" deep that I use for sticks and leaves and other things that aren't quite as heavey but take up more volume. I debated greatly before buying this and now am very happy that I did. I love the dump feature but be careful because there is no stop as to how far it will dump. I was thinking this weekend I may fab up a length of chain or something to regulate how far down the box will swing. I'm sorry I don't have the ability to take a picture but there was a post a while ago with a gentleman on a small Kubota to give you a scale of how big the box is.
