The upright tower looking object between the centralized lube center and the black plastics manuals container is the factory bracket ..
There is of course a matching bracket on the other end of the tool bar ..I know the bracket will hold 2 100lb suitcase weight per bracket as it came with 4 each 100lb weights
I have never had a need for the weights ...so far that is .. my machine w/main seed box only show 2280# ..my reading and relegated to memory the adding of the small seed box adds a pinch under an additional 200# and my native seed box adds another 435# ...so I am trucking along with 2915# + 75# for the weight brackets without one grain of seed in the hopper ..I hope I never encounter conditions where I need the suitcase weights on the drill ..
Tractor is a JD5045E w/ FEL (in which I carry the 4 100# suitcase weights in the bucket when hooked up to "DeBeast"
NOTE: the 3P606NT units have the exact down pressure rating of 90# to 180# per unit as does the 3P600
So I have 9 units on my machine X 180# = 1620# of available down force if springs set to max downward pressure ..which leaves me with roughly 1380# (not counting seed #) to distribute the unused weight to the press wheels and drive tire however the coulters are factory "preloaded" to 450# each BUT ..that does not mean that much weight is being supported by the coulters as they are factory set to be just barely below the line that the unit openers sit at ..
A 3P600 has the same down pressure as the 3P606NT of 1620# and weighs 1466# big box only and 1586# with small grain box added but no coulters in place to rob weight from down pressure effort ..so full grain boxes would get you close (600/700#) would come close to maxing the penetration ability of the units on the 600
