7.23.1 Scrub Speed
The flow control valve for the scrub chain system can be adjusted using the electronic actuator
switch. This valve controls the flow to the inside scrub chain motor.
There is a second hydraulic control valve that controls the flow from the inside scrub chain motor
outlet to the outside scrub chain motor inlet. This valve must be adjusted manually. It is located on
the rear of the harvester. Slowing the outside scrub chain creates a greater difference in speed be-
tween the inside and outside chain. This results in more cleaning action.
NOTE: The larger the difference in the chain speed, the greater the chance of additional damage to
the beets.
7.24 Head Shaft Sprocket Dimensions
The distance between the head shaft sprockets, idler sprockets, and idler rollers is important. The
schematics shown in Figure 7
- 41 are a good starting point for sprocket and roller placement.
IMPORTANT: The dimension indicated by G below is the distance between the face of the sprocket
and the walls of the elevator. This dimension must be equal on both sides of the shaft.
IMPORTANT: Center Idler (H) must be offset from the center belt of the chain. The belted portion of
the chain making contact with the idler will result in chain damage.
