Block Heater Surprise

It sounds like, to me, that Kubota intended the glow plugs to be on when starting the engine. By being in gear the safety interlock should kick in preventing you from actually engaging the stater but the glow plugs still come on.

:thumbsup:
This seems logical. I suspect trying to start with the PTO on, and not just shuttle shift out of neutral, also enables the "extended glow plug workaround".

This also means glow plugs come on during summer starting too?

Well it does not sound logical to me ! The glow plug cycle occurs automatically before the starter is engaged. If the starter is engaged before the automatic cycle is complete the glow plugs are immediately shut off.

Why would you say Kubota intended the glow plugs to be on during starting ???

I have not tried the glow plug work around with other safety interlocks like the pto lever but agree it may be that they work also. That part is logical.

I have heard that but I have never tried it because it always eventually starts. But you got me thinking and maybe it would be a good thing to do. I do have a heat gun.

I had a grey market Yanmar that had no glow plugs (it was supposed to have some kind of bowl that had diesel in it that ignited and the flames were sucked into the manifold but didn't work) so a hair dryer worked fine just blown into the air filter intake. No need to remove the filter. Anything that produces warm air will make the cold diesel crank.
