Section 5 – Operation
Row Unit Gearbox
The main ring gear (C) that drives the stalk rollers in
each row unit gearbox on the Drago GT corn head has
an internal radial pin slip clutch (D). This allows both
of the stalk rollers to slip independent of the rest of the
row unit should a foreign object be encountered. In the
event the stalk rollers slip they will remain timed.
Stalk Chopper
The Single Chop and Twin Chop+ stalk chopping
gearboxes are protected by a radial pin slip clutch (F)
located at the input gear (E) into the gearbox.
Jack Shaft Shear Bolt
The shear bolt (H) is additional protection in the event
of operator error such as ingestion of foreign objects or
incorrect head angle. Its function is to stop any power
spikes to the combine to prevent damage to the
combine (drive shafts, belts, etc.). The shear bolt is
located on the hub (G) on the jackshaft between the
heavy duty gearbox and the intermediate gearbox. The
bolt is an M12 x 60 x 1.75 grade 8.8.
Note: Do not install a larger or higher grade bolt in
place the shear bolt. Doing so may cause additional
component failure.
