If its it's a light crop you can run faster ,

We don't rake and only run a jd1350 moco (2.5m) so put the highest gear on the pickup. The pick up mainly affects the forward speed so thick swaths then slow it down, light and feed it in as fast as you can provided chop length doesn't suffer.

The bed speed is all to do with forward speed and nothing to do with chop length ( although it will change when the chop length is alerted)
The pick up reel speed MUST be going faster than the forward speed else grass gets trapped under the header
Its only picking the grass up remember.
Too fast and your just wearing the header out for no reason.
I attach the ratios if this helps
hope this helps or confuses
Can explain if you wish .

Pick up tine speeds are to ensure clean pick matched to forward speed. Too slow and you drag tines, and impair crop flow to the auger, to fast and you wear out tine arm bushes and cam rollers.
Auger speed is more complicated.
To travel fast, you need to clear the crop from the feed rollers. The speed relationship between the auger and feed rollers is critical for smooth crop flow.
The cross-flow of an auger is measured in m/sec, if too slow, an intermittent feed happens as the feed-rollers ' snatch ' grass, the result being small batches being delivered to the trailer as opposed to a smooth flow. You may have seen foragers delivering grass to the trailer like a machine gun, as opposed to like water out of a tap.
Because Mengele offer quite a few variations of flywheel speeds and chop lengths (slow for short chop etc) and the pick-up is driven off the bottom feed roller, ensuring the right sprockets are on the pick-up relative to flywheel speed and chop length is important.
Most like a pick-up going like hell
However, the objective should be as slow as possible to reduce wear.
