We can only get the separator to slowdown to 400 RPMs. Any ideas on how to make it go slower, at least to 320-350RPMs?

Thanks

Are you sure the 2 speed gear case is in low?

I cautiously reply with a yes. The lever is in the "2" position.

Give'r a shift, see what happens.
I think '2' is high.

From Deere's website...

- high range from 380 - 1000rpm
- low range from 210 - 550 rpm

Methinks you're in high.
