I can’t help with the cross over. I will tell you what I did. I have a MF 1250 aka Iseki TK 532. I took one of the MF filters to Auto Zone and proceed to open up boxes until I found one that fit. It was a Bosch 3400. I was also looking for a longer filter to help clean the oil better and that was it.

Try calling a place that specializes in heavy duty truck parts. Racor filters are hard to find in West Virginia. A local truck parts outfit crossed it to an instock Luberfiner filter and that was a small sized filter.
If anyone is interested, I spent some time with my local parts man at the Bumper to Bumper store today and found the WIX 15460 to be a nice replacement for that Iseki filter. A little skinnier which is good because it was really tight and a little longer to help give more filtering area. Nothing like a really helpful parts man willing ot put in some time on a $10 sale. He knows I'll be back!
