Variable pulley size for driving impeller/augers?

I know that Simplicity had/has a system called Power Boost, which is apparently an automatic (spring-loaded) variable-size pulley for driving the impeller and augers:

Under a light load, the pulley speeds up the impeller/augers, giving you a longer throwing distance, and faster snow processing (less overflow from the bucket at a quick ground speed).

And under a heavy load, the pulley slows down the impeller/augers, providing more torque, and helping you avoid bogging down. This would be nice for heavy EOD use.

At least in theory, this sounds great. I haven't seen much feedback on the system, unfortunately. Has anyone tried it? It sounds like it combines the best of both worlds, more throwing distance when you can afford it, and reduced bogging when you're in really-heavy stuff. We have multiple choices for ground speed, having that for the snow-processing side could be helpful.

Better yet, has anyone retrofitted something like this onto their machine?

I've seen this before on equipment and a similar system on mini-bikes many many years ago, and it worked on those.
