I think that the proublem may be from the angle of the head not the knives. If the head is running too flat it will cause the knives to heal out and push the stocks and not do as good of a job cutting. I would check the angle of the head, it should be between 25 degrees to 27 degrees. this can be measured on the deck plates with an angle finder. or the operator manual tells how to check by measuring the distance from the center of the miter gearbox to the ground. with the skid plates on the outer end of the row unit just touching the ground, the distance between the center of the miter gearbox and the ground should be about 400 MM or about 15 3/4 inches.If your combine has an adjustable face on the feederhouse it is easy to change the angle of the head. if it doesn't there is an adjustment on the head that can be made tochange the angle. that is also explained in the operator's manual.
I hope this helps if you have any questions post back or send me a e-mail, my address is listed on the site.
Thanks Hoes
Yes, it is well explained in the user manual. All you need to to is read the manual carefully.
