When it was quite cold, with my old L185 I would hold the key to the glow plugs for about 20 sec to get it started. Then if it ran raggedly, I'd switch the glow plugs on again for half a minute or so until eventually it would run OK without. I never worried about it.

Same with my B7100.... normal for my tractor.

i need a full thirty seconds when its cold out, and even then it's rough, i'll throw the key back over glow it till it smooths out
