LP tractors in North America ran Propane. They DID run higher
compression because Propane has a base octane (knock index) rating of
115.
In europe Butane was more common than propane.

Along the Texas Gulf Coast there are still quite a number of tractors
running on Butane since the farmers' houses still use Butane rather than
Propane for their appliances.

While Butane appliances are hard to find, there are still quite a lot of
them around.

As you can imagine, it rarely gets cold enough around here for Butane to
fail to gassify although there _have_ been rare occurences.

Most of the LP-fuelled tractors around here are all the same color: Rust.

And if you find a complete propane fueled popular brand tractor these
days it's worth real money. Many of the popular models lost there heads
to guys who are using them on "stock" pulling tractors.

In the states getting pure Propane is a bad bet. Normally a
mix of hydro-carbons. Propane and Butane and whatnot - a.k.a. LP gas.
The mixture might change depending on the outside air and price.

Butane goes liquid as temperatures drive towards freezing. Propane won't.

Around here it may get near/at/below freezing 1-3 nights/year. <grin>

That's why Butane's popularity was so high in this area.

Butane, now, seems to be used mostly in "lighters" and "pocket torches".
