Farm Kabza law

Person "A" has taken Crop loan and pipeline loan from Society/ bank worth of 5 lakh on his farm land 3.5 Acer. 3 years before when Person "B" purchased that land from Person "A" promised to pay that society/bank loan and paid 5 lakh less to Person "A". Person "A" has sold his farm land to Person "B" by proper registration. 2-3 years Person "B" has taken some crop (Tur Dal / Sugar Cane) in that land. In 2017 I purchased that land from person "B" and agreed to pay bank loan and paid stamp duty on 5 lakh while doing proper registration. Mutation is done, Pahani (7/8) is allotted on my name and in that I can see 5 lakh loan is appearing. Now person "A" wrongfully trying to Kabza my land saying person "B" is supposed to pay him some amount. Person "A" has grown Sugar Cane in my Farm land forcefully. I have logged FIR against person "A" and he has taken bail from court in that case. I reached Police and Tahsildar to give me protection so that I can cut that Sugar Cane from my land but they are asking me to get permission from Court since Person "A" has nurtured Sugar cane in my land forcefully. Please suggest what I need to do here to cut that Sugar Cane and get Kabza back to me.
