Guessing the Mihindra is going to be quite a bit less than the others you mentioned. I know the TYM603 we recently purchased was quite a bit less. One thing when comparing different tractors is to consider the price of necessary options configured on each. This can make a big difference in end cost of a tractor over the base price.
The best way to find out is to call or stop into local dealers and ask. Have a list of options, such as gear drive, FEL with joystick, # of rear remotes, PTO (540-1000), sway control 3 point, creeper, shuttle shift, etc, etc, If you are not sure about tractor models give then your HP requirements and list of necessary options and go from there. This will also give you a feel for how the dealer will treat you as a client which may make a difference regardless of cost.
Another thing to consider between the different machines will be output of Hydro system in GPM and lifting capacities of FEL and 3 point depending on tasks you will need to accomplish. If you will be using a lot of PTO attachments also consider the PTO HP rating for each machine.
Good luck
