Initially, the company used a de Prony Brake
system for torque measurement.
There is no flywheel to allow you to connect to an outside load, although Jim Briden came up with a tumbling rod assembly that allowed the roller to connect to the prony brake
, where it produced 31 bhp (brake horsepower).
They put the engine on the prony brake, they join in the daily parade and they engage onlookers in a variety of ways.
A few years ago, while testing horsepower on the prony brake, Bob Anderson--a longtime Gaar-Scott engineer--tucked a bit of coal in the boiler's back corners.
The engines were fired at the factory and tested on a Prony brake
(a unit similar in theory to today's dynamometer), placing a measurable load on the steam engine being tested.

This "machine" is in fact a prony brake
, which is used to measure the output of an engine such as the tractor.
I enjoyed the history of the Gaspar de Prony brake
and Doug Wise's demonstration machine (Farm Collector, January 2008, page 22).
If you had a Prony brake
, you could find out in no time.
The steamers were shown on the Prony brake
and a separator threshing oats.
Also Saturday evening we'll hook one of the engines up to the Prony Brake
and just play around.
