I'm 99+% sure it didn't come standard with a block heater.
The S2800A was used in M4950 tractors, so a Kubota dealer might could help you. It may go in a freeze plug hole.
The S2800B was apparently used in a skid loader. What is your engine powering?

You can also install one in the lower radiator hose, if there's space. Some on here prefer that.

Hi yes there is one installed but don’t feel it’s doing job. Right at the in-line is hot but I have put my hand around to feel for warmth don’t notice any.
Are these inline heater supposed to work by a siphoning action? Don’t feel any mechanical part moving coolant.
I should feel the rad coolant warm if plugged in over nite? But it’s not.
It would be easier maybe to change that inline with one that moves coolant.

I have installed a heater in cab tied into the from motor to rad at the return to rad. Works fine. Butcould that affect the movement of heated coolant?
Thanks

Just a test removed hose’s for cab heater I’ll see if I get warm coolant movement.
It’s about 8 or 9 ft of hose and maybe another 12 inches inches above motor height or maybe abit more 14 or 16 inches
Thanks

Sorry I can't be of more help. I'm in southern US and never had a heater.

Don't run the block heater all the time, 1: it will burn out faster then you would like, and 2: it will really hurt your wallet, they pull a lot of amps.
Plug it in about 2 hours before you want to use it.
