Seeking a used grass mover or grass cutter or tiller to purchase

I am Chandran from Tiruchirappalli and our farm is located some 30 KPS from Tiruchirappalli city .It is an one acre land . We purchased the land with a 450 sq ft house. We have planted some 60 coconut saplings but only 50 have survived . On either side of border of the land grass has grown very thickly. We have removed some but we are planning to go for a used tiller or grass mover. If any member wants to sell the machine we welcome it . Now in an ambitious way we are going to plant casuarina saplings for we welcome suggestions and ideas from farm members and farmers. Thanks.
