 I haven't actually figured out what a cascade box is yet! And I thought that the PTO speed is governed by whether the Mog has a 2 speed or single speed 540 pto box?

I didn't realise that chippers often run 1000rpm, so thanks for that! Sounds like I'll need the 2 speed box at the very least then.

Back to the beginning, how does a cascade box work?
