9400, 9410, 9500, 9510, 9600 and 9610 Combines With Variable-Belt-Drive Feeder House

The corn head drive speed is varied by changing the speed of the lower feeder house shaft. Lower feeder house shaft speed is changed with the plus (+) or minus (-) switch located on the hydro or multi-function handle.

Push and hold the bottom of switch to increase speed, push and hold top of switch to decrease speed.

Engine and header must be running to adjust speed.

Shaft speed of variable drive equipped feeder house ranges from approximately 520 to 785 RPM.

Use the following table as a guide in matching corn head speed to combine travel speed:

Approximate
Combine Travel Speed		 Approximate
Lower Feeder House
Shaft Speed
 
less than: 4.0 km/h (2.5 mph) 520 rpm minimum
  4.8 km/h (3.0 mph) 625 rpm
  5.6 km/h (3.5 mph) 725 rpm
greater than: 6.4 km/h (4.0 mph) 785 rpm maximum

 

The range of row-crop head operating speeds can be changed by the position of row unit drive sprockets.

Transverse Shaft
Driver Sprocket		 Row Unit
Driven Sprocket		 %
Change
     
25T 30T -15
25T 25T  
30T 30T  
30T 25T +20

 

The higher speed positions of these sprockets are used only when travel speeds consistently exceed 6.4 km/h (4.0 mph) or for more aggressive snapping action.
