OT: diesel farm equipment, was Re: [Vwdiesel] winter fronts

[Drew MacPherson]

Yes, the IH design was quite effective for cold weather starting, but the
four cylinder heads had very complex castings that were thin and prone to
cracking, especailly when the machine was shutdown hot.  My father-in-law
has 4 tractors with this setup, one still needing head repair because of
these cracks.

The six cylinders used separate heads and the castings were less prone to
cracking.

His TD5 (made in Hamilton, Ont.), uses a little British 4 cylinder with
glow plugs.  Nice engine, but as usual, the wiring sucks (no offense to
any Brits on the list... :) )
