That wide belt gives it away, I had a similar drive based on the rpm of 
the engine on a tote-goat back
in the middle '60's.

In that case, centrifugal force squeezed the sheeves together on the 
motor shaft, and the driven sheeve
was spring loaded so it had about the same tension on the belt 
regardless of how wide it was split. There's
a name for such a drive but at 88, the recall of that name fails
.
There wasn't enough pressure to start closing the driver sheeves at 
engine idle, so that was its neutral gear.

I always described it as capable of 15 mph on flat ground, and about 3 
mph climbing a pine tree. The diff was
engine rpm, about 4 grand from an old 3hp briggs on flat ground, to 
around 3 grand digging a ditch with its
huge lugs on the back tire. Above 2 grand you moved or dug a ditch.

Here the stick controls the spacing between the sheeves.

Personally I much prefer a vfd and a 3 phase motor. But I'm your local 
cnc guy when Jon Elson isn't looking. ;o)>
