hi, I am interested to know why you want a paddy. Whats wrong with the present lemon orchard?
Some details about the land topology, area and its surroundings might help.
Wonder why you want to remove the 8 yr. old lemon trees which might be yielding in full at this age. To my understanding, lemon plantations are a high value crops and fetch maximum lease/rent amount.
Best regards, Ratna Kumar
It would be better to share the reasons to remove the 8 years’ old Lemon trees.
If the reasons are beneficial to you then according to your idea, you should use JCB to pluck out the trees, push them out and then level it using leveler.
Wish you all the best
