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 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 corn head operating speeds can be changed by the position of row unit drive sprockets.
