ND | I purchased about 8 yrs ago a 1980 643 that was made over into a 8r22 with all plastic GVL snounts. 3 yrs ago replaced the JD fluted rolls with Calmers & the job is does is almost like a new Deere chopping corn head-all it needs now is the swinging blades under the head. Rebuilt the gear boxes in half the head with the heavier gear. The stalk comes into the middle of each row now & it leaves a 24" shank standing & everything above this is in, 2" pieces. The cross auger is getting thin now. Also replaced the center deck plate under the auger as it was wearing through. The 40 series heads I was told were good for 14000 ac but not sure if that was/row or the whole head. | |
