Replacment Diesel Engine for Mahindra 2525

i got a mahindra 2525 from a family member, had a bad knock, rand it for about 45 mins and it thru a rod through the bottom of the engine. I can't find parts for this tractor, is there a place that sells a replacement engine? is it worth fixing? I have a bucket, and the rest of the tractor is in good shape.

Or should I just part it out, the hydraulics,the bucket and rest of the tractor are in great shape.

Willing to use an aftermarket if it fits?
