NH Hayliner banana bales

Hi all, We're having an issue on a NH 68 Hayliner where the feeder teeth (the steel ones; not the aluminum tines) don't reach far enough into the corner of the "pickup chamber" to grab the hay. This results in jamming of the pickup and, I,think, banana bale formation. I suppose we can live with the banana bales but the jamming is another story. Any tips on adjustment or parts replacement?
thanks,
Paul in VT.
