I think on the other board you said they were like the weights below.
I wonder why Ed Gooding didn't give me credit for that photo. I always give him credit when I use his. Oh well...
These are 3 piece and weigh 75 lbs X 3 = 225 lbs per wheel.
I have had these weights on 4 or 5 different tractors now. I'll sell you my tractor but Not the weights.
They will fit any 28" Ford style rim/center combo.
Generally you can expect to pay about 50¢ a pound for weights. So $250 is right in the zone.
I prefer cast iron to fluid ballast for a couple of reasons.
One is it is easier to transfer them from one tractor to another, two, you can always sell thyem if you choose to. Also, if you get a flat you wont see your cast iron running out onto the ground.
DO NOT buy this style weights unless you get the 12 special mounting wedges that go with them.
A little more info if I haven't bored you already:
When you install them you want to tighten them up good all around. Then tighten them again.
Then use your tractor for a few days and tighten them again. If you hear them creaking they have loosened so listen for that.
Last thing, I have seen rims rotted out from mud, etc getting caught between these weights and the rim. A couple of times a year I blow out any crud in there with a pressure washer.
I really like these weights. From the outside you can hardly tell you have them on. I would not sell mine for $300.
