Likely, and with both feeder faceplate and MacDon tilted full forward would likely be steep enough to dump rocks off.Our rock dam on our fd70 has reduced the rocks coming into the combine by half. We have way less rocks to empty in the stone trap than without the rocks am on the knife. I know Don you do not like these things but I would not run a Macdon flex draper without it now.
Maybe one could get his rocks off without leaving the seat.
I have those stubby McKay lifters and I thought I had the skidshoes in the middle hole but have them in the highest cutterbar off ground position, think I’ll move to middle position allowing flatter knife angle and perhaps pick fewer rocks?
A couple of other early observations, ended up cutting peas N/S with a direct N wind, side window wiper/washers are a lot handier than you may think.
The rotor and cylinder drives are extremely positive, almost feels like a chain drive, I suspect the driven variable drives being auto greased the reason.
