What he said. Grind them flat. It is like scissors that are a 1/16 of and inch apart trying to cut paper.
old iron 5400 new knife issues
My family farm runs a 5400 spfh. The main gearcase went out in it three years ago and I rebuilt it. Put a new clutch in it the old one looked good but didn't feel like taking a chance. I also put new cutter knives in it they are just the old j-knife style is what I call them. I used the special height tool to set them went to set the shear bar or cutting bar and on both ends of the knives I have a large gap but in the middle I can get it to its .005 to .015 range. I took a straight edge and the new knives have a arch to them the old ones where straight across on the cutting edge. Has anybody seen this before and what have you done to fix it?
