HCC Reels for Combines and Swathers
... HCC Reels are constructed with tines spaced at 6-inch increments and bat tubes assembled to stagger the tines. This innovative layout reduces bat wrapping, reduces reel weight, and creates an effective tine path of 3-inch spacing, reducing working distance between tines by one third. HCC Reels effec ...
