If it has a front hitch, then I assume most aftermarket plows would fit. You might also want to look at the Intimidator snow plow, since they make the Mahindra UTVs. I assume that what fits an Intimidator would fit the Mahindra.
If none of those work, you may need to check with the Mahindra dealer and go with their offering. I briefly looked at the Mahindra when shopping around last year, and one negative was the lack of aftermarket support for accessories and attachments. Now, things may have improved since then, since it's been a year, but back then Mahindra was the only place to find many attachments/accessories and they didn't have a whole lot.
