This is a 4-cim, 4-minicim drive.
This year, we ran a free speed of around 17fps with 4 cims only and had no problems accelerating at all. 1678's 6-cim drive was geared for around 22fps. This is an even more powerful drive, so I bumped it up to 24fps. The math works out; for anything more than a couple feet it is easy to use high gear (with < 0.05s of lag behind low gear).
The sprocket is the output of the PTO. It is not mounted to the module, but shifts on the shifting shaft.
