Dear mihir1974,
1. You can have couple of cows or a few goats on your own which will eat all the grass.
2. You can request your neighbour land owners if they have the above to host them in your land so that you both can get mutually benefited.
I am not sure whether you are having any plants or doing anything in the land. If that is not the case, you do not have to worry about the grass as they will enhance the soil.
