Mahindra has a threaded plug, just for the heater purpose, and I wouldn't go knocking out a freeze plug to install a freeze plug heater/

What Galen is trying to say is that your Mahindra has a 3/4" NPT plug that you remove... to install a 3/4" heater in it's place. On my 5035, in the lower radiator hose, Mahindra has provided a big cast iron inline holder for installing the screw in heater. Your 4530 may have a similar setup, or you will find that 3/4" NPT plug somewhere else. If you don't want to buy a screw in heater from the Mahindra dealer, you can find them on Ebay or Amazon... Just make sure you do not buy one that is too deep for the hole it has to be screwed into. You can still go freeze plug if you want, just don't have to... I don't think my 5035 even has 'freeze plugs'... you know, the big holes the engine manufactures put in the side of the block so they can hold the sand form in place, then clean out the sand from the casting process.... press in some steel plugs.... and call them freeze plugs.

I bought a Kat's 11619 3/4" NPT type screw in heater for my 5035. It's a 600W and looks to be about 2 1/4" deep when seated in the 3/4" pipe threads. Comes with the plug in cord. You can get these on Amazon for about $37... again, don't know if they are too long depth wise for your tractor...

Yup, no freeze plugs on my Mahindra. You probably don't have them either. My old John Deere 2240 doesn't have them either. They all have replaceable cylinder sleeves instead of the ' cast in block ' type. Those need the freeze plug holes to hold the sand form in place for the coolant passages around the cylinders... thus end up getting freeze plugs.

Has anyone tried installing the "Kats 11619" or similar into a Mahindra 3016?

I don't think you'll find one necessary.

I was contemplating some sort of an engine/battery heater for my 3016, but have found it starts excellently without either. It's been below 0 degrees F here several times this winter and it starts like a champ. I'm not going to waste my time or money adding anything.

That's why I have not been a big hurry to install my Kat's heater in my 5035. Starts pretty good even with limited use of the grid heater [ I put a swich in line on mine that keeps it from firing up in the summer. ] But I have spent quite a bit of time downstate with family matters this winter, and wish I had put it in since the barn has not been heated up each day. So, in it goes next summer... and fresh antifreeze.

I installed a heater in the radiator hose of my 4035. Not because it makes trouble starting, but if I plug the heater in for a few hours before I start it, the engine starts running smooth a lot quicker. If I don't use the heater, it starts but spits and sputters for a longer time.
