I don't know if you may be looking for the bolt on adapter to uses regular barbell weights on your wheels. I keep looking at the device but don't actually have them yet. They are from eZweights http://www.ezweights.com/aboutez.php
Kubota L3560, Toro 52" and 60" ZTRs, Kubota RTV 900
Neil; How much do the weights that you mention weigh? I like the idea of wheel weights better than loaded tires because much of the time that I use the BX, I neither need or want the extra weight. I would be happy to buy the Kubota weights, except they only weigh 50 or so pounds, and there is no way to mount more than one on a tire. My dealer quoted me a price of around $50 for the Kubota weights.

Will....... you can purchase the weights locally from almost any garden tractor dealer that sells a tractor that has a 24x12x12 rear wheel, such as JD, Bolens, Wheel Horse, etc. Look on e bay and other such places. I don't think that you are going to find much more than 50 pounds per weight, but you should try to avoid the shipping at all costs, because that is going to add a lot to your ultimate cost, but not add any value in the end. Do a search on e bay for garden tractor wheel weight and see what comes up. I just did one for Bolens wheel weight and found 4, but none in your area. They are out there, but you will just have to be patient or you will just have to pay more if you are in a rush. The choice is yours.
If you want the e-z weight system, here is an auction for them starting at $39.95 for just the brackets, without weights. to the auction...- Ends Apr-11-04 09:25:45 PDT
