There are several options for you.
Replacing the seat with a new one from Mahindra = $$$$$
Finding an after market bolt on seat without modification (I tried internet, TSC, Amazon, but no luck)
Upgrade to a suspension seat (yeah!!). Requires a little modification, but not difficult. (I used two 2x6 PT pieces of lumber to accomodate the new bolt pattern, and also increase the height of the seat)
Repair the seat yourself. There are some YT videos on how to repair a vinyl seat.
