Agricultural Property against loan dispute. What are my options

My father took a loan on 6acre agriculture land owned by him.he was 80yrs old and give the money to my two brothers without informing me nothing about loan.he died last year without paying loan as he couldn't pay loan. he made a will that this land (6acre) would be divided among his 3 sons(2 acre each). Now my brothers refused to pay loan. And property will be registered to me(2 acre) only after paying the loan. What should I do now to own my share.
