Narrow row head unit

摘要

A narrow row head unit may include a back plate secured to a left gearbox and a right gearbox, which gearboxes may be positioned adjacent one another. Each gearbox may provide rotational power to a pair of stalk rolls and a drive sprocket for a gathering chain. A right mounting tab may be secured to the back plate and the right gearbox, and a left mounting tab may be secured to the back plate and left gearbox. A right plate and leg may extend outward from the back plate adjacent the right mounting tab and a left plate and leg may extend outward from the back plate adjacent the left mounting tab. A narrow row head unit positioned left-of-center on a header may have the gathering chain positioned substantially over the right plate, and right-of-center substantially over the left plate.
