Just traded the 9500 in on 9550. I have a 925 ridged header. I was told that I needed to make sure the cutter drive was slowed down so I don't have problems. I have gone thru the owners manual and it also tells me I need to slow the drive down. but I cant find anything about the actual process. any help would be deeply appreciated. thanks

You will need a smaller main pulley on the knife drive.
There are options available at your dealer.
You will have to do the math on how the ratio changes.

I have been swamped with haying and havnt really had a chance to look closely at the 9550. I assumed it would have a variable speed feeder house. tonight I went to the shed and did some detective work. this machine is a fixed speed unit. the chain on the right side of feederhouse is on the big sprocket. which is the slow speed. looks to me that I am in good shape regarding platform drive speed. I have the Lankota 50 series driveshaft kit waiting to be installed. I wish everyone a safe harvest.

With fixed speed it should be slow enough the way it is. Our 9650 is fixed and have never had problems with running the knife too fast.

If you mean the front sprocket right side of feeder that only affects feeder chain speed and if on large sprocket that would be the fast speed as that is a drive sprocket.
I don't think you should have any issue with knife drive if you have fixed speed feeder.
