COMPARE

The four-gear six-speed Jeffrey Haulage with a
twelve-gear one-speed continuous cutting Haulage.

With the Jeffrey Machine, the rate of travel
can be varied from ten to ninety yards an
hour without stopping the machine.

The one-speed continuous cutting Haulage can
not be changed without completely dismantling
a complicated train of gearing.

We guarantee to replace any broken clutches
or haulage gears within two years caused by
our friction clutch not slipping.
