The ice cream unit is powered by a 1 HP John Deere hit and miss engine.

648 Marticville Road Pequea, Pennsylvania 17565

I have the belt system spring loaded so that the belt on the six
quart will slip when the ice cream is ready. The power then shifts
to the 10 quart; when that belt slips, the ice cream is ready, and
then all the power shifts to the 20 quart. And it is ready when the
final belt slips. Trial and error gave me the correct tension and
torque on each of the drive belts of each freezer. The trick is to
start the six quart first, and then get the 10 ready, and then
after starting it, get the 20 quart ready. By the time the 20 quart
is starting, the six quart is about done, and the 10 quart takes
more power. By the time the 20 quart is laboring, the 10 quart is
done, and all the power shifts to the 20 quart. Starting all
freezers at the same time would eventually stall the engine before
any of the ice cream is completely hard.

Incidentally, an old White Mountain technical paper suggests
(hand-crank average) of 110 rpm for the 20 quart, 90 rpm for the 10
quart and 80 rpm for the six quart. With 550 rpm coming off the
4′ pulley on the engine, I used different size (diameter) drive
pulleys to achieve the recommended rpm at each freezer.
