If you are not comfortable with the freeze plug removal, I purchased one of these several years ago and it can be moved from one tractor or (vehicle) to another.
Assuming of course that your tractor has a steel oil pan. My LK3054 does not. Didn't discover that until I'd bought a magnetic heater (think I got mine at TS).

The stickon magnetic heaters may be better then nothing but a 200 watt stickon is going to do a lot less
good then the same inserted as a block heater. And the last time I looked most block heaters where 2-400 watts.
I bought the block heater from Kioti a year ago and never installed the thing. Mine is a 2610 with old style fuel injection pump, yeah the ones that don't like starting cold. Well the other day it was a little below zero and I cycled the plugs just once and the engine fired right off. I think I'll leave the heater on the shelf.
There is about 1/4" of space under the freeze plug before the block cylinder wall. Permatex #51813 anaerobic sealer works great for a sealer.
So I got the anti freeze in today but now the lower radiator hose has a small leak. I don't think it was leaking before and we didn't even touch the hose. It didn't have fluid in it for about 36 hour if that makes a different.
