Hey guys, I bought a NI 309 Picker this summer for my deer corn business. I love this thing. I pull it with an IH 484 and run in 2 low at 1500 rpms. And 3 low sometimes. I'm running in good corn. I would like some input on this. I don't want to feel like I'm wasting time. Also are there any good, bad points of this picker. What year is this. Serial# 208773.

If my memory serves correctly, for a NI picker the ideal ground speed is around 3.5 mph. At this speed, the snapping rolls at a normal pto speed of 540 rpm, should "feed" in the corn in at the same pace you are moving forward. This prevents "grabbing" of the stalk and violently pulling in (moving too slow) or the opposite effect which can result in uprooting the stalk and then "dragging" it thru (moving too slow). Unfortunately the pickers were designed in an age when 200 bu/acre was almost a pipe dream. Consequently one can easily overload the husking bed with todays yield when operating at 3.5 mph. Dad had a NI 325 with a 8 row husking bed, and traveling at 3.5 mph was just not possible after about the first 10 ft. I have a big soft place in my heart for unusual equipment and particularly NI stuff, since I am originally from Ohio. I bought a NI 331 picker and removed the 328 husking bed and installed the 329 sheller. Although I don't do much with it, you can run it at 3.5 mph in 200 bu/corn and the stalks just slide in. With the MM G950 and a 300 bu wagon, I'm transfixed to a kinder gentler age that is now sadly long gone.

Correction If you are up rooting the stalks and dragging thru, should be: you are going too fast
