Combines F curtain over walkers

Tim, If you have a chopper definitely leave the curtain in behind the walker otherwise you will beat the crap out of the back of your walkers. The setting of between 5_8"-3_4" for corn depending on moisture,size of cob and yield will determine this. Cyl. speed and air should be close. I normally slide walkers all the way back.

The curtain above middle of walkers won't matter but you MUST have curtain at back above chopper and it should hang to just clear knife swing.Previous owner of my F2 had a short curtain and it beat holes in sidewalls as well as schredding ends of walkers.

does your chopper have a slower pullyIJ my f3 allows me to switch pully on chopper to slow it down.

Only one size pulley on it.
