I don't recall needing the heater to start a 6-354 provided the engine
was in good condition.
Perkins diesels were a bit sensitive to bad fuel and I recall spending
lots of time repairing fuel components especially when they were fueled
from drums left outside.
The 3 cylinder engines were most likely a 3-152 which were very common
in Massey Ferguson tractors, they were bloody hard to kill, I remember a
trade in that wouldn't start that the workshop foreman eventually got
running with a can of aero start.
When dismantling the engine to find out why it was making such horrible
noises I found the crankshaft was broken in 2 places:-)
