Unless you are going to be selling the tractor as soon as you get it running, forget the "sealers". Results, if any, are temporary. So what if they refund the purchase price. Who cares? Your tractor is still broke.

The success of any repair is going to be based on where the crack is and who fixes it. If the crack is in a place that is under a lot of thermal stress, it will have to be welded by a certified welder with plenty of experience in cast iron block repair. If small enough, a good weld might do it. Let the welder tell you.

If the crack is quite large, the block is toast. Sure, you can heat them in an oven, weld them, remachine the entire block, and rebuild the engine but it would likley be cheaper to buy another tractor.

Small cracks in non-stressed areas can and have been fixed by epoxies. I like JB Weld. The crack must be cleaned with brake cleaner, must be perfectly dry, and the instructions on the JB must be followed to the letter.
