Are counter balance weights for the front ends universal

[Hummer70]

I have a Kubota B7200 HST and there are no counter balance weights on the front end. There was room for three but PO welded on a trailer hitch there.

The finish mower that came with the 7200 that gave some excitement as I drove up on my trailer the front end came up about two feet but the high rails on my trailer stopped it from getting off the ramps and I got it loaded OK. When I got it home I did not raise the finish mower all the way up and when I backed it off the front end did not come as high so I thought I would try to find two counter balance weights.

Are these weights more or less universal or are the restricted to brand of tractor? If so is there a number on the weights I can look for to assure they fit my tractor?

If anyone has a B7200 I would appreciate a drawing of the weight I need and any markings that may be on it? Even better a pic of the weights. Thanks

UPDATE:I just found a pic of a "Suitcase Weight" with a 5011 number cast in that is supposed to be for a Kubota. Is this what I am looking for?

If the hitch is a receiver, make something that will slide in it when extra weight is needed.

No it is just a standard flat bar he cut down. Good idea about receiver hitch though. I can't believe folks want around 100.00 each for the suitcase weights. I will be on the lookout at flea markets etc. I have seen them for sale but never thought I would need them.
