WAYNE - I think KRAIG nailed the ID.
Growing up down south of the Border... the WIS & IL border that is, with the hundreds of IH M's, H's C's, and newer Super series tractors, 300/350/400/450/200/230 I never saw anyone use a set of front wheel weights on a FARMALL. Many other ways of adding frt weight were used but no wheel weights.
SO, I never knew that those frt wheel weights WOULD FIT on the rear wheels of a Cub Cadet. They weight 42# each, and to mount on a CC you use one of the recessed holes and the hole 180 degrees across from it. The bolt circle is the same, the weights just seat inside the very last little lip on the rim or butt up against it, they're larger in diameter so won't recess inside the bead of the rim like the CC weights do. I learned THAT @ PD #1.
SO I'd grab them, they should have an IH logo cast in them somewhere. And they'll fit a CC. Most IH weights now bring A Buck a pound, sometimes less as is the case with the H/M/C one-piece rear wheel weights which weigh 150# and normally cost $60-$80/pair. So any price less than $80-$100 for the pair is good, YMMV, and all the other disclaimers apply.
